I just want to note that A. consanguineum is a pretty easy species to
"bulk up" without TC, given the large number of offsets it produces from =a
very young age. When we grow out seedlings for selection, we isolate each
tuber starting in the third year and keep all its progeny with it - that
way, by the time we make final selections, we have a bunch of younger one=s
ready to grow on and multiply.  The named selections we offer are all
vegetatively produced from an original clone.

I'd be interested to hear whether TC arisaemas mutate and/or vary the way=,
say, TC hostas do?  I would think roguing out arisaemas before they're
fully mature would be a little tricky.  Tony?

A couple of years ago an Indian friend, who run=s a nursery in Kalimpong with a modern lab, and I have selected exciting =new forms of well-known Himalayan species which will come on the market s=hortly. These forms have been put on tissue culture and I have also send =Chinese species to him which will come on the market in 2-3 years.

Unfortunately Arisaema are not really commercially interesting to prod=uce in high numbers but it is my intention to let my friend tissue cultur=e some rare and endangered species too which (hopefully) will be introduc=ed to the market in small numbers.
