A. tortuosum self-fertilizing (?)

[Martin Ashworth]

Hi Mary
I have 2 tortuosum, both 'flowered' both bisexual, one has set seed one has
not. I cannot say, re note from Guy, if it has self fertilized or if it has
crossed with some other male. I have several 'males only' appearing at the
same time. Will keep Group posted on outcome.

AEG posted and tell us if they germinate. But how to be sure that no cross
has been made between the bisexual tortuosum and another arisaema in the
garden?
