Hi all,

Most species of the section Arisaema (the big three leaved Arisaemas) are easy to grow in the garden.
They seem to prefer cool and rather moist conditions.

1) A. asperatum
2) A. griffithii dark form emerging
3) A. griffithii dark form (a few days later)
4) A. propinquum
5) A. utile
6) A. dilatatum

Robin,

That dark form of griffithii is unbelievable (but in a good way!  ;)).  So dark!!  Wow!  :o

An amazing plant. It looks so sinister.

In Belgium perhaps. Most species die in the winter in my place    :'( and I am sure it is due to cold.
I nearly gave up on all but amurense but for those who like me live in a cold climate I can report that
serratum and maximowiczii survived this winter too.  :)
It is still far from flowering time but they are up and healthy-looking.

Göte,

Have you ever tried to protect the tubers from heavy frost by a thick layer of pine needles or leafs. I always do that but temperatures go seldom below -10° C in our garden.

This dark clone hasn't set seed so far. I hope it does this year.

Robin
I am afraid that I have never been able to protect anything this way. I have stopped trying to protect because I A: it did not work B: I would have too much work doing it.
I follow Tony Avent: I"I regard all plants as hardy until i have killed them three times"  ;D

Hi all,

A. erubescens often confused with A. consanguineum. A. erubescens has a pinkish flower emerging before the leaf unfolds and a smaller number of narrow leaflets without the typical long threads of consanguineum.

A. dahaiense is probably the largest Arisaema in my garden up to 1.50 m tall and 1.50 m wide. Easy from seed. Has a spadix appendage more than 1 m long.


1)A. erubescens
2)A. erubescens
3)A. speciosum
4)A. dahaiense (motherplant flowers)
5)A. dahaiense (seedlings 2004 leafs )
6)A. dahaiense (seedling 2004 flower)
7)A. dahaiense (motherplant leaf)

Beautiful stuff, Robin,

I had an unknown Arisaema start to open today and now I believe it is A. speciosum.  I bought it as A. candidissimum, but the tuber was all wrong (cylindrical and annulated).  I'll send a photo when it is fully open for confirmation.

Wow Robin!  Never seen the dahaiense before.  Very nice flower and leaf by the look of it.  Thanks for sharing.
Cheers.
