You are correct in that some species don't need tc unless you are
looking for really large numbers.&nbsp; After five years of tc, we have n=ot
seen a single mutant yet.&nbsp; I'm still looking for the white edged for=ms,
but no luck.&nbsp; Those with silver patterns do not show up as patterned
until they mature and have gone through two dormancies.

<pre wrap="">I just want to note that A. consanguineum is a pretty ea=sy 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?

<pre wrap="">Jim,

As Tony already says, tissue culture of Arisaema is becoming a good way o=f propagating Arisaema. A couple of years ago an Indian friend, who runs =a nursery in Kalimpong with a modern lab, and I have selected exciting ne=w forms of well-known Himalayan species which will come on the market sho=rtly. These forms have been put on tissue culture and I have also send Ch=inese species to him which will come on the market in 2-3 years. As Tony =says, tissue culture has 2 advantages: reducing the pressure on wild spec=ies and the possibility of introducing selected forms as cultivar because=a cultivar is only a true cultivar if it has been propagated vegatively.=Unfortunately Arisaema are not really commercially interesting to produc=e in high numbers but it is my intention to let my friend tissue culture =some rare and endangered species too which (hopefully) will be introduced=to the market in small numbers.
