Amorphophallus X Arisaema???????? What is this word coming
too...........siiiighhhhhh.
One short party-pooper: it is well-known in the plant world, that alien
pollen sometimes excites ovaries (watchit ladies, this is getting
XXX-rated........) to develop "clonal" seeds, so they are then in fact ex=act
copies of the motherplant. My guess is this is what happened in that insa=ne
cross between Arisaema cordatum X Typhonium (what Typhonium??). I think t=he
Arisaema world would have better benefit from a pure cross of Arisaema
cordatum so we can share more plants of this species from outer space,
Petra! Have you tried that one too?
Cheerio,
Lord Ariphonium........yukkkkk.
