Guessed name for Taratahi Lilac' based on the following:
I received this tuber in trade. It produce lovely, full blooms in September, a decent size, about the same as Camano Sitka, with a similar incurved cactus form. It is also similar to 'Orchid Lace.' Listing in my notes as 'Taratahi Lilac' for now, but linking only to the generic Dahlia database listing.
