George,

I get seeds this year from A.Flavum grown from the same clone ( I
started them from seeds of a single plant 3 years ago );

A. Concinnum do not set seeds easily here in my garden, even if I
planted in different flowerbeds, more than 30 tubers bought in
different years.

The same for A.Costatum ( more than 70 tubers planted two years ago,
most flowered, high plants, beautyful leaves, some children this
year, no fruit.

I got 6 small seeds from a young plant  from a medium tuber of
Amurense ( ssp. angustatum ?  gift from an AEG member  ) grown  in a
pot  kept very  far from other Arisaema plants .

Giorgio
Italy zone 7 .  very dry and hot this last week.
