I grow some terrestrial Utricularia indoors. I use the standard peat/ sand for the soil and keep the plants in a tray of rainwater. The water is usually very high, almost at soil level. The plants seem okay with that setup.

I am growing utricularia calycifida indoors to the side of my grow lights. The plants are in pure sphagnum and standing in a tray that is 1-2 cm tall. I have three flower stalks right now and the plants are growing well.

Mostly same as both of the above. However, for most non-South American terrestrials, especially semi-aquatics or U. gibba, I either add or solely use some of the peat sludge that sinks to the bottom when rinsing peat, since I expect that's closer to their natural soil. Don't know that it makes much difference, but U. cornuta has done fantastic in it. Calycifida and its relative longifolia aren't technically epiphytics or Orchioides members, but they're similar enough I use either pure lfs or live sphagnum or a peat/perlite/lfs mix. For me, Calycifida seems to prefer the former while longifolia likes the latter. For water level, I maintain 1/4 to 1/2 up the pot for Calycifida/Longifolia/epiphytics and just above empty to 1/3 up for more typical terrestrials like sandersonii, unless they're a semi aquatic like cornuta in which case I keep them undrained and flood every few days.

Utricularia in general seem to be really flexible, so as long as you keep them sufficiently wet and use a peaty mix (for most terrestrials) you should be fine.

I get pretty frequent flowers from my U. bisquamata. I think the annuals flower more because they have a need to seed as their lifespans are shorter.

U. calcydifa and sandersonii are both easy to find and flower prolifically. U sandersonii seems happy and has flowered just about everywhere that I’ve put it. I haven’t succeeded in making longifolia happy enough to flower yet but hopefully I’ll get it figured out.

I had a colony of subulata once that would only flower when it received abundant direct sun, and the temps were 85+ for an extended period with warm nights. Might have been a humidity issue in there too but heat and humidity go hand in hand around here so who can say. By the way, dang those things are weeds.

I have a pot of Utricularia that refuses to fully open, it's probably also subulata. It's also been outside in the scorching AZ sun during monsoon season. Still won't bloom, it sort of makes these buds that seem like they'll bloom but then they fall off and seeds from.

May I ask where in AZ you're located?

Should say in my profile.

Gary wrote: ↑Mon Aug 01, 2022 5:27 am Aha! Yep, you are definitely getting some hot weather.

It's hot enough that the flytraps are burning and the capes needed to come in. Now, the question is, where in AZ are YOU?
