I bought some neat seeds and now I'm not too sure how to start them. I've got
Thunbergia fragrens
T. gardiflora alba
T. coccinea
I searched the web and found little about germination. Anyone out there try any of these?
While I'm at it... some others I could use some help with are Brunnefelsia, Crossandra, and Tropaeolum peltophorum.
Thunbergias...
OK,where'd ya git'um.......
I got them from Chiltern's. If I can get em to germinate I'll have babies to share ;)
OK, here is what I found
Sow seed at 61-64 in the spring. Best taken by cuttings in the summer, however, I have cuttings going now and they aren't dead yet! Now, I have T. mysorensis, T. coccinea that I am trying to root. The T. coccinea is actually doing quite well. CC your mysorensis has not taken off but it ain't dead. The best way to root these cuttings have been with a plastic bag over the pot. You would be welcome to them if I am successful.
The only one I found reference to was t. fragrens--70-75 degrees, 10-15 days (Treasury of Gardening)
crossandra-do not cover, need light to germinate, 75-80 degree temp in the medium during germination which takes 25-30 days. (Park's Success with Seeds)
tropaeolum peltophorum--I only found majus, is that close? What is the common name? Is it still a nastursium?
For t. peltophorum--resents transplanting, either use peat pots or sow outdoors after frost. Germinates well in neutral soil at 68-70 degrees (Plants a Plenty). Figure this next bit out: Germinates 7-12 days, do not cover, needs light to germinate, 65 degrees (Treasury of Gardening). Now get this: Same as above except--Seeds must be completely covered as they need darkness to germinate (Park's Success with Seeds).
If the "experts can't even agree on that part, I guess we just have to experiment ourselves.
Which brunfelsia? Yesterday, today and tomorrow? Couldn't find anything about the seeds.
Hope some of this helps, but some of it confuses.

Thanks for all the info. I guess I'll just plant the thunbergias and hope for the best. I've read some different info about the tropaeolums... some require cold but I think a period of warm first won't hurt.
Got my fingers crossed.
I'm so excited.... I have two thunbergia coccinea seedlings popping up. http://www.kwekerijgommer.com/fotos/Kuipplanten/Thunbergia%20Coccinea.HTM Nothin on the T.grandiflora alba or T.fragrans yet. But.... there's hope =]
I start thunbergia mysorensis in water..they root in a reasonable time and good.I have two types of mysorensis type..one gets really wild and covers things like kudzu!!LOLPretty flowers though.
Any tips on germination from seeds of the different thunbergias? Seeds from grandiflora were saucer shaped. I planted some in soil but I saved a couple to do in paper towels. The T.fragrans were round. I did a few of those in soil and a few of them I nicked and soaked before I planted. Still nuthin from any of them....
