Random plant event: Anthurium andraeanum double spadix

Apologies to those five or so readers to whom I owe e-mails. You're on the list, and I'm working on it, but, well, I've mentioned that I'm busy, right?

This particular flower is both a freak and a rescue. I bought it last September from Lowe's, because it looked like it was basically fine except for having been drowned (this being, apparently, the only thing that Lowe's knows to do to a plant). Brought it home, cleaned off the roots as best as I could, repotted it in good new soil, and then watched as about 2/3 of the plant died. But it's come back.

I think it's maybe still a little traumatized, though:


I've seen double spathes before, on Anthurium as well as Spathiphyllum, but I think double spadixes (spadices?) is a first for me.

I give the plant points for at least trying to meet me halfway: it's clearly not quite got it together yet, but hey, it's trying. Maybe the next flower will be normal.

Or maybe it won't. I suppose it would be cool if I had a plant that always produced a double spadix.

Personal-ish: Marriage (Almost)

Front of the Iowa marriage license application. I got to be "Party B!"
I'm not a big fan of change, but if things are going to be changing anyway, then we may as well do all of it at once. (This is otherwise known as "As long as the noose is around my neck, I may as well jump off the horse" logic.)

The husband and I applied for a marriage license yesterday, though we are not going to be going forward with the actual ceremony immediately, because certain house-related things work out more neatly if we don't get married until after I'm done with my job. But this is kind of close enough for now anyway. Our apartment manager, who was also our real estate agent, graciously agreed (on really short notice) to serve as our witness¹ for the application, and consequently is so totally getting a houseplant or a flower arrangement or something.²

Back of the Iowa marriage license application. Note the "Competent and Disinterested Person" bit.)
The date is also significant.

On April 30, 1997, twelve years ago, a few minutes after the end of the much-hyped "Ellen" episode where Ellen officially came out as gay (even though everybody knew for like, months before, and were sick of hearing about it already by the time it aired), I called my parents and told them I am gay. This wasn't because I was especially bonded to Ellen DeGeneres or anything: I like her, and I had watched the show, which was funny enough as sitcoms went, but it wasn't like I felt that if Ellen was coming out then I had to as well. It was more just, it had been increasingly difficult to talk to Mom and Dad about anything that was going on in my life around that time: among other things, I'd just gotten back from an abortive 64-day move to DC, involving an ex who I'd not been entirely willing to think of as "ex" yet,³ and although I talked to Mom on the phone a lot, at least weekly, not being able to acknowledge the nature of our relationship -- or, increasingly, any of my other relationships -- made for some awkwardness.

The new house comes with a very large maple tree in the back. It indicates something or another about the property line, though we're not sure exactly what.
They took it better than anticipated, though it'd be a stretch to say they took it well. I was kind of a wreck before and after also, as far as that goes. Which is another story, for another time. The point being, that was the date. At that time, there was a little bit of talk about gay marriage in Hawaii, possibly, enough to scare people into passing Defense of Marriage Acts all over the place,⁴ but nobody seriously believed that it would be legal anytime soon.

This is what will eventually become the plant room. Originally a three-seasons room, we're going to try to add another season. Seasons, it turns out, are not cheap.
So there's been a lot of change already, I guess is my point. Fairly recently, a CBS poll showed a jump of nine percentage points in one month of respondents who favored full marriage equality, to 42% of the U.S. population, and an ABC poll this week came up with an even higher number, 49%. That would basically have been unthinkable to me twelve years ago: my expectation was that when I did get married, it would have to be a ceremony with no legal significance, and it'd be regarded as weird at best, offensive at worst. Instead, it looks like we're going to get the legal significance without the ceremony, and most people won't really give a crap. Which would be delightful.

By the way: the recorder who helped us with the application said that Monday (the first day same-sex couples could marry in Iowa) was pretty crazy for them, and Tuesday was nearly as bad, Wednesday was pretty slow, and then Thursday would have been slow except that everybody from Monday was coming back to pick up their licenses. We didn't see any other couples when we were there. She also said that they had sixteen or seventeen (I forget which) couples coming up from Missouri on a bus tomorrow to get married. Apparently then they'll go back to Missouri and say they're married and gin up a court case or two when they find some people in Missouri who don't recognize this. It's unfortunate that lawmakers don't seem particularly interested in considering the constitutionality of laws when they're making them, that everything has to go through this process of being challenged and sorted out, but better that than have legislators passing any old law that flits through their heads. That would be terrible.

I have an aunt and uncle who will be doing everything in their power (which is not very extensive, but still) to prevent the Missouri people's marriages from being recognized: I wish the various couples luck.

The previous owners' attempt at a garden. Nothing identifiable here. It makes me a little uneasy that they felt they had to fence it in: I'm developing a serious fear of rabbits all of a sudden. ("Bunnies! Bunnies! It must be bunnies!")
The actual official marriage will probably be in June, though I dislike the idea of having a June wedding (just 'cause everybody else does it: November or December are more my months, but that's a long time to wait). That's when my job will be over. It'll probably be really low-key and anticlimactic, but that's okay.

We do have some concerns, still, about moving to a small town (and by small, I mean small: under 1200 people). We'd really rather not be everybody's first married gay couple. I feel enough like a target as it is.⁵

We inherited these from the previous owners. Not really our style, I think.
So that's the last of the bombshells. Getting the marriage license was mostly just surreal. We'll be back to plant-related content tomorrow, though after all this it's going to seem awfully trivial, I'm afraid.

¹ Amusingly, the Iowa marriage application calls this role "Competent and Disinterested Person," rather than the clearer but less precise "witness." I would love to have a competent and disinterested person around at all times.
² Why her? Well, it turns out that there are not actually very many people who know both of us in the area, and even fewer who would conceivably be available on short notice to do something like this, for one thing, and for another thing, she has a gay brother in Vermont, who is I believe civil-unioned there and who will (one assumes) be getting married in September when Vermont starts doing that. So we were guessing that she's basically okay with the general concept. According to her husband, who I spoke to for a little bit this afternoon, she and her brother were sort of bragging on their respective states for being the third state to legalize (Iowa) or the first state to legalize legislatively, rather than judicially (Vermont), so one supposes participation in a gay wedding gives her more points from which to argue, or something. She didn't say, and we didn't really talk about it: she had other things to do.
³ The DC period was a miserable time, though the misery wasn't because of the ex. Culture shock, undiagnosed clinical depression (I'm pretty sure.), graduating college without any kind of plan for what to do next, a week of the flu, and various other things, but not really the ex so much.
⁴ Which I'd never known exactly what the DOMAs actually said until today: they're apparently primarily there to ensure that the states with DOMAs don't have to honor same-sex marriages performed in other states, even if they were legal in those other states. Some states have actually gone further and pre-emptively banned civil union sorts of arrangements as well. At this point, there's a law or constitutional amendment banning gay marriage in every state except New Mexico (hasn't passed anything one way or the other), Iowa/Connecticut/Massachusetts (have full marriage equality), Vermont (will have full marriage equality as of September), New York, DC, and Rhode Island (will honor marriages performed elsewhere), and New Jersey (has civil unions). Every other state prohibits SSM to some degree or another, though several states (WA, OR, CA, CO, HI, MD, NH, ME) have one set of laws approving some form of same-sex partnership and one set banning, simultaneously, which will need to be worked out at some point in the near future.
⁵ Not that people in small towns in Iowa can't also be perfectly accepting and friendly and everything else, or that big city folk are always live-and-let-live about everything: I've met one Iowa City resident who looked like your run of the mill sweet little old lady, but had a personality that could strip the paint off the walls, set the paint chips on fire, and then turn the ashes to poisonous snakes. It's just that small-towns are sort of known for everybody being all up in everybody else's business, and this is kind of a weird thing to walk into deliberately, given the circumstances.

Personal-ish: Job

Petunia (grandiflora?) 'Tidal Wave Silver.'
Second bombshell (of three) for the week, and probably the one my readers will find most surprising: I'm quitting my job. I told the boss on April 23rd. I'm going to be working through at least May 23, and then probably off for a week, and then maybe I'll be back one or two days per week through the middle of June or something. A lot depends on how horrible moving is, and how out-of-control life is feeling by late May.

I have mixed feelings about this, though overall I think it's more good than bad. If nothing else, I'm not sure my poor body would be able to handle another summer of this. I mean, we know the heat is an issue, and that time of year is getting closer. There are a lot of other reasons why this seems like the thing to do now. Some of the reasons sound better (or at least normaler) than others.

Rudbeckia hirta.
I've been kicking around various plant-related ideas for What To Do Next: I couldn't really become a wholesaler (startup costs are prohibitive), but in theory there's nothing stopping me from propagating plants on my own and selling them. The town to which we're moving is rumored to be starting up a Farmers' Market this summer, and many of the towns in the area have Farmers' Markets of their own, so that could be a source of income, in theory. Failing that, maybe EBay or something. I don't know. I've also been told a few times that I should look into writing, either for magazines or getting a book proposal together, which just as soon as I find out how and what one proposes to a book I will totally do that. Writing, at least, seems like a pretty duh kind of avenue to pursue, since I was doing that anyway.

The husband should be able to cover us financially, BTW, especially since the house payment is going to be about half of what we were paying in rent. I mean, we'd be giving some stuff up by not having the extra income, but since one of the things we'd be giving up are heat exhaustion and back-breaking labor, it seems worth it to me.

Catharanthus roseus 'Peppermint Cooler.'
This, like with the move, is also going to have repercussions for the blog, because (in theory) there will eventually be vastly more time available for writing and researching and photographing. I've been feeling guilty for quite a while now about not keeping up better with everybody else's blogs, so this might give me the chance to comment on other people's posts and link to other people's blogs and so forth.

The down side is that I'll have a much smaller pool of plants available for pictures. I mean, obviously I'll go back to my current employer from time to time, 'cause it's still the best source around for plants I might want to buy (though -- will it still have a selection perfectly tailored to my whims and needs if I'm not the one putting together the orders anymore? Probably not.), but I'm not going to be able to go back and spend hours looking around for photographable stuff. At least not daily. (Not that I do that now, but I do spend hours around the plants, and sometimes photographable stuff appears.) And also I'll have less inside information to share about what working in a garden center is like, or possibly I'll still have the information but it won't be as immediate to me, so I won't find it as interesting, or whatever. But that's maybe okay, right?

Verbena 'Aztec Red Velvet.'
I feel very weird announcing this, in a number of ways but mostly because this is something of a risk, and I'm not ordinarily someone who likes to take risks. (Though staying at the job was not without its risks, either.) Doing it anyway, but it feels weird.

Personal-ish: House

Yesterday the husband closed on a house in another town (not Iowa City, though relatively nearby), which we will be moving into at some point. I've never owned a house before,¹ which was, I thought, a pretty good reason not to be into outdoor plants, so now we're going to find out if I really think tropical plants are superior, or if I was only saying that because I couldn't have any temperate-zone plants.

Obviously the blog is going to suffer a little bit in the short term; although the husband has already rented a storage unit in said town, and has been moving stuff into it for about a month now (he's a glass-half-full kind of person; he's thought the deal was going to go through for a lot longer than I have), there's an awful lot to move, and of course I've been busy enough with work and the plants and the blog and whatever else it is I do, so my stuff is a lot less, er, dealt with than his.

Sempervivum 'Red Beauty.'
Exactly how much the blog is going to suffer is yet to be determined; I'll let you know.

As for the gardening: as best as I can tell (I've only actually seen the place once, and that was at night), the yard is mostly sun. It's basically a long thin strip that extends west from the house. There's a tree at the far end, and there will be a fence on the north and south sides of the property, but there's not really anything else for shade.

Portulaca 'Tequila Mix.' It's only just getting started now; it'll be more awe-inspiring later.
I've already bought some plants for the yard (The glass is occasionally half-full for me, too -- particularly when optimism means I can buy plants): so far we have a whole flat of Portulaca grandiflora 'Tequila Mix' (moss rose), because it's the best annual ever,² a Lantana camara 'Rose Glow Improved,' because I have positive associations with it now, a smallish pot of strawberries (Fragaria 'Fort Laramie'),³ a Sempervivum 'Red Beauty,'⁴ Lysimachia 'Goldilocks,' and I have some 'Quarterback' coleus⁵ from last spring that I kept as a houseplant, as well as brand-new-this-year 'Kingswood Torch,' 'Glennis,' 'Peter Wonder,' 'Splish Splash,' and possibly others I'm failing to remember. I like coleus. The coleus won't necessarily end up outside. In fact, I have no idea what I'm going to be doing with most of this stuff. To begin with, I'm just buying the plants I like, and we'll see how that goes, and we'll worry about having some kind of coherent plan next year. This year, we're just trying out the outdoor gardening thing to see if it's any fun. I've been told it is, but I remain skeptical.

There are perennials I like too (Lysimachia is supposed to be a perennial here.), but I don't know any of them terribly well, and most of the ones I do know somewhat and like okay are shade-lovers that I don't think will work that well for this situation. Shrubs I know basically not at all, and trees are not a good idea, I think, because we may want to put up a greenhouse in the back someday, and planting trees and shading the whole back yard could make a greenhouse kinda useless. Also it's not that big of a yard anyway.

Lysimachia 'Goldilocks,' in extra-dramatic lighting.
I'd also really like to find something for the lawn besides grass. I mean, the grass that's there already is fine and all, but mowing, weeding, spraying, watering, etc. all seem like really dumb ways to spend one's time. I hear there are other things that can be used instead, but I've seen very little about what, specifically, or how one goes about replacing grass. Anybody know any good references?

Pictures of house and lawn to follow . . . when I get around to it. The husband reports that there are Hostas.

¹ Technically, I still don't, since the whole deal has gone through under the husband's name, but I think he's going to let me live there anyway.
² So long as the rabbits don't eat it, which Kim tells me they like to do. I believe her exact words were "rabbit candy." Worrisome, but I'm still going to try.
³ (We had NOID strawberries in the back yard when I was a kid. I went ahead and bought the 'Fort Laramies' already because it looked like we were in danger of selling out of strawberries before the house thing went through. Strawberries are all but flying out the door this year.)
⁴ My good grandmother had Sempervivums outside her front door. (Like some people, I had a good grandmother and an evil grandmother, both of whom were into plants. Evil grandma went for ornamentals, irises and clematis and snapdragons and tulips and so forth, with only a few vegetables. Good grandma had less time on her hands, so she went more for vegetables, with only a few ornamentals. Both of them had houseplants: evil grandma probably deserves most of the credit -- or blame -- for my interest in them. By most measures, I take more after evil grandma than after good grandma.)
⁵ (Solenostemon scutellarioides)

Random plant event: Calathea zebrina concinna flowering

A bit of a palate cleanser to follow the plant toxicity series. (Yes, I know I did something different yesterday: my palate still doesn't feel cleansed, okay?) In the next week or so, there should be some personal announcements from me that are going to necessitate some changing around of . . . you know, things, and so I don't feel like getting into another major post right away. Also I just finished a major post, which also makes me not feel like getting into another major post right away.

Anyway.

We've had Calatheas bloom at work before, though they've been different kinds of flowers in the past (stiff, orangish, on thicker stalks), and they don't happen very often.


I tried to get a close-up picture, but none of them turned out particularly well.

[Exceptionally] Pretty pictures: transmitted light -- Part IX

It's transmitted-light photo time again! This particular batch rocks much harder than usual.

(The previous transmitted light posts can be found here.)

Cyclamen persicum NOID. Not especially interesting, but what were you expecting? The leaves are way too thick for any interesting venation to show.

Eucharis grandiflora. Better. I can't remember now whether or not the color might have been tweaked just a little on this photo. Maybe it was, maybe it wasn't. They are very green.

Saxifraga stolonifera. This is the kind of discovery I make these transmitted light pictures for: I don't think I'd have ever noticed the spots on the underside of the leaves otherwise.

Aglaonema 'Golden Bay.' I wish I had room for one of these at home. I mean, not that I don't already have plenty of Aglaonemas, but this variety is particularly nice. There's just no spot for one to go, anywhere.

Spathiphyllum 'Domino.' Though this picture shows the variegation, it doesn't show the weird leaf texture so well. At first, I didn't notice the texture, and then I noticed it but didn't really think about it much, and now I notice it and think it's kind of bizarre and wonder what is going on with this plant.

Peperomia caperata NOID. The colors are weird: I can't decide if I like them or not. Focus is somewhat improved by opening the picture in its own window.

Laurus nobilis. I find it interesting that some plants, in transmitted light, look like light-colored leaves with darker veins running through, and others, like this one, look like dark-colored leaves with lighter veins. I haven't made a careful study of the matter to see whether the light-vein plants are all related or something; so far, I've just noticed.

Codiaeum variegatum 'Mrs. Iceton.' Sometimes I think crotons maybe just have too many colors. Makes 'em look all . . . busy.

Plasticum artificialis marantoides. Yeah, okay, this one shouldn't be here, technically, as it's not a real plant. I told myself it was for the sake of comparison.

Codiaeum variegatum, possibly 'Petra.' This was my header photo for a while.

Rumor

According to Foreward Magazine's review of the new (as yet unreleased) Amy Stewart book, Wicked Plants, the book will contain the sentence,

"Some of the most popular houseplants are surprisingly toxic."

So perhaps there will be houseplant content after all. If true, this would please me.

Houseplant Toxicity Week Appendix 2: Index

If you have landed on this page because you are concerned about a child or pet who has eaten a plant, seek emergency medical help.
In the U.S., you can call Poison Control at 1-800-222-1222 (for children), the ASPCA at 1-888-426-4435 (for pets; $60 consultation fee applies), or the Pet Poison Helpline at 1-800-213-6680 (pets; $35 fee applies).

Second appendix to the seven-part-and-two-appendix houseplant toxicity series. (Part 1) (Part 2) (Part 3) (Part 4) (Part 5) (Part 6) (Part 7) (Appendix 1)
This is the index for the Houseplant Toxicity Series of posts. If you have reached this page first in a Google search or whatever, I recommend that you find the plant on this list and then follow the link to get more specific information about that plant. If the plant's botanical name is highlighted, that means that it was the subject of a plant profile here at PATSP, in which case you can also click the plant's name and find out care information, trivia, and so forth.
Toxicity ratings are more or less decided as follows:
Crazy super dangerous: is highly toxic, and has either resulted in repeated human or pet fatalities, or is for whatever reason thought to be very likely to do so.
Dangerous : Fatalities are rare or nonexistent, but the plant is still capable of causing serious and possibly permanent injury requiring hospitalization, extreme pain, temporary disability, or something along those lines. Dangerous plants may make you want to die, but you probably won't actually die. Though the possibility is theoretically there.
Potentially dangerous: This designation is for plants which are probably capable of causing harm and maybe even death, but you'd have to eat your body weight in the plant for that to happen, or it's impossible to find any actual case reports, or etc. Potentially dangerous plants will probably be more risky for pets than people.
Unpleasant : The plant is not likely to kill you, or even to result in serious injury, but it may be capable of causing vomiting, bad skin or eye irritation, diarrhea, burning, itching, or other bad things, and you don't want to eat it on purpose. This is also the designation for plants which are otherwise safe but bear thorns or spines that could puncture the mouth or digestive tract.
Safe : Should be safe in most quantities and for most people/animals, though exceptions may exist.
Unknown : I couldn't find enough good information to decide one way or the other, or I found the information but it conflicted with other information. I did make a guess as to the level of risk on the page for unknown-toxicity plants, but this is only a (semi-educated) guess and I am almost certainly really wrong on one or more of the plants therein.
I know the formatting on this page needs some work (EDIT: Some of the problem is that Google changed how Blogger pages are formatted in the spring of 2012.), and that it's hard to read as it stands. I did the best I could. Putting together a draft of this index took me a good three hours to begin with; I didn't really have the patience to spend time fiddling with the formatting too.
