I have successfully grown T. polyphyllum from seed. For the 
life of me, though, I can't tell what if anything the magic 
touch was. IIRC they were subjected to my usual regimen for 
hardy things: sown and the pot parked in a coldframe over 
the winter.

It may be significant that the seed was fresh, off an 
established plant in my garden; they were probably sown 
not too long after they were ripe, but sowing may have been 
delayed until winter.

These seedlings have been grown on in very large pots and I 
will get flowers this year for the first time, so maybe 
there will be yet more seed.

I have had reasonable success with *germination* of seed
from the exchanges in the past, but I didn't know how to
grow them on. I always soak my seed for up to two weeks
before sowing.

So: it can be done.
