Hello Tony and all, Is the solid silver coloring found in some Arisaema
taiwanense (Silver Heron) and Arisaema consanguineum (cultivars that
Seneca Hills sells), actual a "blister" variegation (air trapped under
the epidermis causing light to reflect a silver color) like found in
silver mottled and colored Cyclamen hederifolium, Begonia sp.,
Pulmonaria, and others?
Or do these just fall under the blanket of natural variegations with
the white centered Arisaema sikokiana and others?

So if these are "blister" variegations, then cultivars like Arisaema
consanguineum 'Poseidon' have "blister" variegations with an overlaying
natural variegation causing the whitish central area, which both are
"true-to-type" in every cell of the plant.

I have found true chimeral variegation in Arisaema ciliatum and
Amorphallus konjac, but they are usually sectorial and do not repeat
the next year.
I am looking also for that perfect periclinal variegation in Arisaema,
it would be so great.

I am working on a variegation paper currently and trying to get this
all straighten out.

Thanks, Jake

We haven't got any variegated arisaema yet...just hoping to do so from
the tc process. If the variegation is a stable chimera, then tc usually
has no problems producing true to type offspring. If the variegation is
sectored, then reproduction through tissue culture is difficult. The
silver patterns are not really a true variegation and therefore
reproduce fine via tc.

I understand that with some variegated plants, tissue culture will not
capture the variegation.

If the starting tissue is the green part of the leaf you will get a
green plant, if the sample is in the silver part, you get a silver
plant.

Do the variegated arisaema follow this rule?

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