Lisa, that's another chilean species (the one with the largest growth and blooms), but I have not tried it. Some 13/14 years ago I found a place where they grow wild. Although the vines and flowers had all dried back I knew they were T.s. because of the size of the dry plants (climbed up and then down large trees - looked like a curtain) but I was delighted to collect some seeds. I shared part of the seeds here (or was it DG at that time?) and sold some on internet and ..... forgot to keep a few for myself.
I have longed to go back to that place to see them in bloom and take pictures, but ........ each way is app a 2 1/2 hours drive and my osteo-arthritis does not cooperate with such long drives.
I do have some seeds of my pot grown T. azureum if you and the other T. lovers want to give them a chance.
It´s funny, but my double as large T. tricolor pot and older/larger plants, placed on the same balcony (I'm back in the big city) did not produce any seeds(picky pollinators?).
Last year I sowed some really old seeds of a gorgeous pink hybrid produced in Japan, but although 1/2 of the really old seeds germinated, they were sown(sowed?') too late in the season to bloom. I hope they bloom this year.
