Hi all
To continue with the self fertile / hybrid issue. If my tortuosum has
produced viable seed and this appears next year with a trifoliate seed leaf,
will the seed be viable if stored (what is the best conditions) for Seedex
2007? It is a particularly nice specimen, snakeskin pattern cataphyll and
stem + plant is over one metre tall.
With the exception of 2 natural hybrids, the Book, triphyllum and
dracontium, tortuosum and consanguineum, all other natural hybrids mentioned
are Japanese and all from the same section, pedatisecta. Are plants from the
same section more likely to produce viable seed and plants, than possible
hybrids of plants from different sections?
I also have a costatum setting seed, obviously a female but male is ????.
