Finally it's gotten warm enough that this year's outdoor plants can all stay outside for a few consecutive days, which makes my life a bit easier. (It's also been very rough on me mentally -- it's just too weird to be hoping for the weather to be warmer.)
I'd put the younger Eucharis bulbs (the ones I bought two years ago) outside a while back, but then it got cold for several days, and I put all the plants back in their previous spots while we rode out the cool spell, and then for some reason I had neglected to move the Eucharises back out again when the weather improved. They were only out for a couple days, but apparently that short period of brighter light was all the encouragement one of the plants needed to decide to produce a bud.
The smell is as nice as I remember, though it's been a long wait. I didn't move the plant back outside until the flower was already well underway, but that doesn't seem to have hurt it: it's possible that it's lasting longer than the previous ones did.
I should probably note that the foliage behind the flower is not that of the Eucharis: that's this year's attempt to grow Salvia elegans. The two plants have apparently become friends or something. Which is good, since the Salvia was new and all.
