Crosses

[Bonaventure Magrys]

Last year out of about a dozen attempts, the few seadheads I'd gotten
aborted during hot weather. Probably didn't have fertile seed. 2 others, on
triphyllum, produced 6 and 8 seeds respectively. The first by nepenthoides
had 3 sprout and 1 plantlet survive to its third year with leaves a lot
like the pollen parent, before rotting. Taiwanense on triphyllum have about
4 tuberlets, very slow to resprout this year, left in the garden. (Some
Arisaemas are so damn hard to grow from seed and keep alive, rather the
seed or little seedling, first year tuber, or second year sprout seem to
die off very easily). Candidissimum on which sikokianum was placed has 1
survivor, its early years carefully nurtured by a friend. The leaf looks
suspiciously like its mother, but it may be blooming size this spring
coming.
The triphyllum for taiwanense was bloomed indoors and had no stamens
(carefully checked), likewise for the candidissimum, which was forced into
early bloom.
So far my new seedhead is holding, not fully developed yet, even through a
light frost. When I have a female triphyllum bloom in January (mid-winter
here in the northern hemisphere), or in September as in this case, there is
not much chance of being a pollinating male triphyllum bloom around.

Hello everyone

On the subject of crossing unrelated Arisaema species, I have tried to
impregnate A. sikokianum with pollen from A. erubesence without any success
last year. The fruits did not develop at all.
May be there are some compatibility problems between distant related
species.
I'd be interested to know if there is any success with these kind of
crosses.
