Just a warning---a few years ago I bought 100+ seeds for this plant, and got ZERO germination. Hopefully you'll do better, but be prepared.

Do you have fungus gnats flying around? Could be the larvae from the fungus gnats? I've had the same problem with a couple of my seeds that were kept too wet and the seeds rotted. My solution is to make the soil medium drain better and not hold as much moisture - by adding things like perlite, turface, bark, etc...

I've had my T. mysorensis bloom in a 15 gallon container and with only 8 foot of growth, so they don't necessarily need to be big or old to bloom, especially if they are grown from cuttings off a mature plant, as mine was. On the other hand, here in northern California, it is not exactly ideal climate for them, and they only bloom in mid summer to mid fall. On the other hand, I also have a Beaumontia grandiflora planted out in nearby Alameda on a 3 story tall east facing wall, and it must be about 40 feet across and 25 feet tall, and it hasn't bloomed yet after 5 years of being in the ground. I assumed it may not be getting enough heat or prefers full sun, but I see a much smaller specimen at San Francisco's Botanic Garden bloom every year, but it does get full all day sun. I wish I knew what if anything I could do to get my Beaumontia to bloom!

i've learned alot from planting seeds, LOL too damp of soil with jiffy pots, and gnats. makes bad for these seeds. so if your willing to share or trade with me i'm sooo willing ot trade 3 or 4 to this one. yes i want this pretty darned bad!!! LOL :'))
