List: Houseplants That Have Red Flowers

The usual disclaimers apply, but let's run through them again just to make sure we're all on the same page:

1) This is not an exhaustive list of red-flowering houseplants; I'm not sure it's even possible to come up with an exhaustive list of red-flowering houseplants. And if it were possible, it probably wouldn't be desirable. This is plenty long as it is.

2) Also, many of the plants on the list are available in multiple cultivars, not all of which necessarily bloom red.

3) I'm approaching these lists from an interior-decorating standpoint, not a botanical one. If the plant has showy red bracts with tiny yellow true flowers, I'm counting it as a red-bloomer, because that's how most people would think of it.

4) As there are no sharp dividing lines between "red," "orange," "pink," and "purple," you may disagree with me about the redness of some of the flowers mentioned here. Which if it's all the same to you, I'm going to see that as more your problem than it is mine.

5) In some cases, I'm going wholly or partly by the results from Google image search for the plants in question. Since people sometimes post misidentified pictures, there is a small chance that some of the plants listed, especially more obscure plants, may be included in error.

Aeschynanthus lobbianus.

Clerodendrum x speciosum. (C. splendens x C. thomsoniae)

Cyclamen persicum NOID.

Episcia 'Silver Skies.'

Hatiora (formerly Rhipsalidopsis) NOID.

Hibiscus rosa-sinensis.

Kalanchoe blossfeldiana NOID.

Neoregelia 'Maria.'

Parodia microsperma. Some other Parodias have red flowers as well, though yellow is more typical.

Tillandsia ionantha. Some other Tillandsias have either red flowers (T. funckiana, T. latifolia) or red bracts (T. juncea, T. abdita, T. vinalesensis, T. boliviensis, T. tenuifolia, T. brachycaulos, T. queroensis, T. leonamiana).
This is a tough list to do recommends / anti-recommends for: for all of these, I either have 1) no experience, 2) exclusively bad experiences, or 3) very mixed experiences. If forced to come up with something, though, I would reluctantly recommend Aeschynanthus, Episcia, and Neoregelia.

My personal experience with Aeschynanthus lobbianus was mostly negative, but I don't think it was the plant's fault: I should have kept up better with the watering. Other Aeschynanthus species have done well for me, enough so that I'd feel comfortable recommending them to other people. The main obstacles to cultivation are light (they need at least bright indirect light, and I'd highly recommend at least some direct sun) and temperature (always above 60F/16C).

I enjoy Episcias, but varieties either tend to do really well for me ('Coco,' 'Suomi,' several NOIDs, 'Faded Jade,' 'Raspberry Parade') or really poorly ('Pink Acajou,' 'Kempenfest,' 'Burning Embers'), without much of a middle ground. 'Silver Skies' is one of the good ones, though it's a bit slower than the others, and stays smaller. Main obstacles to cultivation: temperature (always at least 60F/16C), water (don't let them dry out to the point of wilting) and humidity (higher is better).

I was a huge fan of Neoregelia at one point a few years back; I've cooled off on them somewhat since then, for various reasons, but they're perfectly fine plants if you have the space for them and don't mind getting caught on their sharp marginal spines occasionally. Biggest obstacle: light (at least bright indirect, with some direct sun strongly recommended).

For the anti-recommend, I guess I'll go with Hibiscus, though Cyclamen and Kalanchoe were really close. They all can be grown indoors successfully, but none are particularly well-suited to it. Cyclamen goes in and out of dormancy at erratic intervals and is easily overwatered as a result; Kalanchoe virtually always goes downhill once purchased, because it needs extremely bright light.

Hibiscus has both problems: it defoliates in the winter, to a greater or lesser degree depending on how it's treated, and it's very difficult to rebloom in the house if you don't have a lot of light. (Though it's easier than Kalanchoe.) Hibiscus has one problem that the other two don't, though, which is that they're incredibly appealing to pests. At work, we were always wrestling with spider mites, whitefly, and aphids; I've also had spider mites on plants at home. Hibiscus are gorgeous, obviously, but it's just not worth the hassle to bring them inside for the winter. People with huge windows or small plant collections might find Hibiscus more rewarding than I do.

Some of the closer ones: Burrageara Nelly Isler (link; pinkish), Miltassia Charles M. Fitch x Odontocidium Black Beauty link; very dark red), Vuylstekeara Aloha Sparks 'Ruby Eyes' (link; washed-out and orange-red), Wilsonara Lisa Devos (link; brick red and pink), Oncidium Sharry Baby (link; dark red), Miltonidium Bartley Schwartz 'Highlander' (link; dark pink-red)

• Pachira aquatica is not likely to bloom indoors, but the flower has yellow reflexed petals with lots of long, white, red-tipped stamens. You wouldn't look at it and say "now there's a red flower," but there's definitely quite a bit of red involved.
• At least one Pachyphytum sp. or cv. has flowers with dark red interiors, though I don't know which one and it doesn't appear to be typical for the genus.
• Pachypodium baronii has solid-colored, true red flowers; P. namaquanum has yellow flowers with petals that don't open very wide and are red-brown at the tips. All other Pachypodium spp., including the most commonly-grown ones, have white, yellow, or pink flowers.
• A few Pachyveria hybrids have flowers that look reddish in pictures, though pink, yellow, and green are more common.
• Phragmipedium orchids get close to true red once in a while. Closest two I've personally run into were Phragmipedium Sargent Eric 'Timberlane' (pretty true red; a bit orangey) and Phragmipedium Fox Valley 'Fireball' (pretty close to true red, a little pinkish).
• Pedilanthus tithymaloides. (unlikely to bloom indoors)
• Some Pelargonium x hortorum cvv. are true red or dark red.
• Pereskia bleo are either orange-red or red, according to photos; Pereskia flowers are more typically pink/lavender. I don't know P. bleo's suitability for indoor culture, though at least one Pereskia (P. aculeata) does well indoors.
• A few Phalaenopsis orchids tend toward something like red, though I have yet to see any true red phals.
• A handful of Philodendrons produce inflorescences with solid red spathes; the most commonly sold is P. 'Moonlight,' but the species P. eichleri also does. The spathes of P. martianum (aka P. cannifolium) are white with a dark red base.
• A few Pinguicula spp. have true-red flowers, most prominently P. laueana. Maybe also P. caryophyllacea?
• Some Rhododendron cvv. are brilliant true red, though I would argue that they're not houseplants.
• Some Saintpaulia cvv. are dark red or pink-red; I have yet to see true red.
• Salvia elegans.
• Schefflera actinophylla. (dark red, very unlikely indoors)
• Several Schlumbergera cvv. are vivdly red.
• Sedum burrito. (rare; variously pink, coral, or pink-red)
• Sedum morganianum. (rare; photographs show true red, red-orange, dull red, dark red)
• Sempervivum cvv./spp. flowers are typically (but not always) dull red or pink-red.
• Some Sinningia cvv./spp.
• Most Stapelia flowers involve dark red or dark purple-red somewhere, though it's never a particularly vibrant red, and not very many of the flowers give an overall impression of red. Most notable exceptions: Stapelia cedrimontana is black-red with red and yellow stripes near the center; Stapelia hirsuta has very dark red stripes on a peach background, giving the overall impression of dark red; Stapelia leendertziae -- which I also covet -- is solid dark red or dark purple.
• Stenorrhynchos speciosum.
• Stenosarcos Vanguard 'Fireball.' (pink-red)
• Some Streptocarpus cvv. (pink-red)
• Stromanthe sanguinea cvv. (red or pink-red; unlikely to happen indoors)
• Synadenium grantii. (dull dark red, small, unlikely indoors)
• Many Vriesea hybrids, and some of the species (notably V. splendens) produce inflorescences with red bracts.

As usual, I am totally open to it if readers want to make additional suggestions in the comments.

Random plant event: Hatiora (?) NOID

This is a good news / bad news random plant event. The good news is that there was a bloom --


-- and the bad news is that I think it's probably the only one I'll ever see.

And it's already finished.

I got the plant in question from a reader last May. It was very large and full then, and got larger and fuller for several months, which was great. And then in early October, it began to shatter, dropping a few segments here and there. Which was disturbing. Then it did it again in mid-October. Finally, at some point in early November, it blew itself completely the fuck up. (I think the largest remaining piece had about six segments to it. Just, segments everywhere. Oh the humanity.) Also, it got a sort of dusty look to it, like maybe there were spider mites, though I didn't see spider mites on any of the plants that were nearby. And we have a lot of dust here, so it's sometimes hard to be sure.

So I sprayed with neem oil and dishwashing liquid. And was rewarded with another shattering. I pulled all the pieces out, cleaned off any rotten bits, and replanted all of them into new pots and new soil, carefully balancing them against one another so they would stay more or less upright. Then a couple weeks later the husband decided to wipe off the table they were sitting on, and moved the pots of rooting segments, which then all fell out and had to be replanted again, with the careful balancing and etc. But did I say anything mean to him about this? I did not. Because I am a saint.

In the midst of all this chaos, though, a flower bud formed on one of the segments, and against all odds, it developed fully, was open for about 3-4 days, and then dropped off. And then it was over.


The segments have now been sitting for maybe three weeks, undisturbed, and I don't think they're rooting terribly well. Even if they are rooting, they probably aren't going to root upright, like the plant was when it arrived, and I'm not optimistic about the long-term prospects of the plant, but both hope and the plants are still alive.

From the Schlumbergera profile, I see I wrote

Easter cacti aren't particularly popular because they're harder to grow: if they're in a draft, too wet, or too dry, they shatter, dropping all the stem segments, which is obviously kind of a jerky, passive-aggressive thing to do. Also they're less consistent bloomers. Which is also passive-aggressive. Basically Easter cacti are pricks, is what I'm saying. Care is basically the same as Schlumbergera, but the margin for error is much narrower.

The most likely cause, according to that, would be draft, followed by too wet: they're in the plant room, and the door we use most to get in and out of the house is in there too.

There's a pretty good chance, based on the flower color and flower timing, that it wasn't an Easter cactus (Hatiora) after all, but was instead a true-Christmas Christmas cactus (one of the older Schlumbergera hybrids). I have no way to tell at the moment.¹

I don't have any immediate plans to write a plant profile on Easter cacti, but if I did, I'm thinking I'd have to choose Suicide Bomber, or possibly Patsy Cline,² as the "person."

Probably Patsy. Very few suicide bombers blow themselves up more than once. Though an argument could be made for suicide bombers being more passive-aggressive than Patsy Cline.

Hmm.

My other Hatiora NOID, which was sold to me as a wildly-overpriced Rhipsalidopsis, has orange flowers, has doubled or tripled in size since I got it (also last May), and has yet to shatter at all. They've been right next to one another, getting the same care, same temperature, same humidity, so the fragility is soil-related, cultivar-related, or both. For whatever that's worth.

-

¹ Easter cacti were previously known as Rhipsalidopsis, and are often sold under that name, though at the moment our botano-taxonomic overlords are preferring Hatiora to Rhipsalidopsis. These Hatioras also strongly resemble Schlumbergeras, especially the older Christmas-blooming Schlumbergeras, so misidentification is common.
Hatioras are a lot more prone to shattering, as a rule, but both genera can shatter. (My Schlumbergera x buckleyi, also a reader trade, has done a tiny bit of this in early December.) I'm continuing to assume that the plant I'm talking about in this post is a Hatiora, because: that's how it's written down on the spreadsheets and elsewhere in the blog, that's what the original owner thought it was, it allegedly blooms in spring, and the shape and texture of the segments is subtly different from the plants I have that I'm pretty sure are Schlumbergera x buckleyi.
On the other hand, I have no way of ruling out that it's a Schlumbergera either, since both plants could produce actinomorphic magenta flowers in early December. Either time will tell, or the plant will die and make the question moot.

Newish plants

This last month or so is apparently the dawning of the Age of Gesneriads, as far as my personal collection goes. I've gotten a lot of them in trades recently, including my first Columneas, Nautilocalyxes, Codonanthes, Kohlerias, and Chirita. Mostly Episcias, though, because I feel safest with Episcias.

This isn't going to be an exhaustive list of everything I've gotten, because 1) there are too many of them to do that, and 2) some of them literally died before I could get a picture taken.¹ These are just the ones I find most interesting.

First up, since I teased you about the gesneriads, let's begin with the gesneriad I'm most excited about. This is Columnea orientandina:

Columnea orientandina.
Why am I so excited about it? I don't know. It just seems cool. All the leaves have that red spot on the tip of the underside, the flowers are smallish but a nice clear yellow --


-- and it just seems, you know, likeable. Possibly the main reason I'm interested in it is because I'd never heard of anything like it before.

Dyckia 'La Rioja.'
This is one of the ones that died, which was tragic and not-tragic simultaneously. The tragic part is that it was a weird color, plus a bromeliad genus that's new to me, and I think Dyckias have a really cool shape to them. It's not tragic in that the hooks on the leaf margins are wicked sharp, and it would have been all but impossible to handle this plant without hurting myself. A lot.

Hatiora NOID.
The Hatiora (better known as Easter cactus, or Rhipsalidopsis²) is one I actually bought. I've wanted an Easter cactus for some time now, but I've never seen one for sale around here until a few weeks ago. They only had two, and both were more or less bloomed-out, but this was such a nice color (the photo doesn't do it justice; it's sort of peach/orange/coral), and I get so few opportunities to buy them, that I went for it anyway. Paid $10 or $11 at Earl May, which is excessive for a plant this small, especially one that's already mostly bloomed-out, but at least now I have it. So far, contrary to the rumors about Easter cacti, it's held together and not disintegrated into a pile of unconnected segments.

Hatiora NOID.
This, on the other hand, is an Easter cactus I got via trade, so essentially for free, from a reader. You'll notice that it's way bigger and nicer. It will have magenta flowers, assuming that I can get it to flower next spring.

Kohleria 'Peridots Kitlope.' Or maybe 'Peridot's Kitlope.' Not sure about the apostrophe.
I forget what it was (possibly a post at Andrew's?), but at some point not that long ago, I decided that I needed to have a Kohleria, so I started trying to get one. I now have three, of which this is the largest. The person who sent it to me was not enthusiastic about the genus, for reasons which were either forgotten or unspecified, but I think I have pretty nearly ideal conditions for it in the basement, so we will see what I think of it after a decent interval of time has elapsed.

Close-up of Kohleria 'Peridot[']s Kitlope' flower.

Nautilocalyx forgetii.
I know next to nothing about Nautilocalyx. So far, one unrooted cutting of N. pemphidius died almost immediately, and this unrooted cutting of N. forgetii seems to be doing okay. Even if it does well for me, it's not likely to be fascinating -- the flowers are smallish and white -- but it's novel. And maybe it'll do well for me. That always makes me like plants better.

Chirita 'Deco.'
Since this picture was taken, the plant seems to be preparing a flower bud, which I'll have to get a picture of so I can show you, I guess.

Billbergia 'Foster's Striate.'
Easily one of the biggest plants I've ever received by trade (that's a 6-inch / 15 cm pot it's in), and if I can ever get flowers, that should be pretty awesome. It might be awesome even without flowers, actually. There are some concerns that I might not have a bright enough spot for it, but so far it seems to be hanging in there.

Episcia 'Pink Acajou.'
One of the more interesting Episcias.

Episcia 'Silver Skies.'
And another.

Episcia 'Faded Jade.'
There were seriously a ton of Episcias.

Episcia 'Kempenfest.'
The USPS basically backed a truck up to the house and I went in the back of the truck with a shovel and just shoveled Episcias out for an hour or two.

Finally, for the pièce de résistance --

Pereskia godseffiana.
I knew of Pereskias before this, from pictures, but had never been that interested. So it's a cactus with leaves,³ big deal. The reality in person is much stranger. First of all, I was not prepared for the color. Pereskias are usually green, but this is hot pink and brownish yellow. It looked more like a badly-wilted pink poinsettia than a cactus. Second, even though there are leaves, there are also thorns/spines/whatever, which are seriously sharp, and hide at the base of the leaves, which wouldn't be that big of a problem except that I had to try to bend the leaves upward in order to keep from planting them along with the stem, and they don't really want to bend, so I was stabbing myself repeatedly while trying to pot the cutting up.

I'm a little worried about it: they're supposed to be incredibly easy to root, but nothing seems to have happened so far, and the leaves are a little floppier now than they were, which is possibly a bad sign. Granted, it's only been here a week, and I should give it time.

If it does work out like it's supposed to, then I will have a fast-growing, hot pink and brownish yellow plant on my hands that longs to be a thirty-foot vine that bristles with thorns.

¹ Not really my fault or the sender's fault. First of all, they weren't a trade so much as a gift, and there were time constraints on it such that they had to be shipped during a cold spell in late April. They're still in the process of sorting themselves out, as far as who's going to live and who's going to die, but at the moment about 2/3 of that group are still technically alive. How many of them will stay that way, on the other hand, I have no idea.
² But Plant List will back me up on Rhipsalidopsis being a botanically obsolete name.
³ If memory serves, Pereskias are thought to be the living group of cacti most similar to the ancestral cactus from which all the others descended. Hence, they still have actual leaves, and need a fair amount of water, and so on.
