Very vigorous yet well behaved climbing vine. i bought three seedlings online last year 2011, and my biggest one one, on the north side of my house, is now 7', growing next to clematis 'Walenburg'. I love the texture of the flower...it feels just the way it looks...like dense styrofoam...and it floats! i'll take a pic soon....i just love this funky species...it took me forever to find it, however, which is why i purchased 3 when i found it...in case i killed one or two. None have died...all are thriving. I have the other two growing separately...one through a redbud, and the other through a Don Juan Rose.

A little more detail on germination from the 2nd edition of Norman C. Deno's book, Seed Germination Theory and Practice -

If you obtain the seed too late for fall sowing, sow in the dark at 70*F; germination may take about 3 months.

I rescued this plant(actually I got 3) from a construction site in North Georgia where it grows naturally, although sparsely. Grown in full sun it can be treated just like a Jackmanii. Trim old growth in late winter as flowers appear on new growth. Once established, this vine produces flowers for about two months, Late April-June in Zone 7. Quite an agressive grower/climber it can take over a small arbor or trellis in one season.
