Topic of the Week--Arisaema
J.E. Shields (Tue, 19 Aug 2003 05:58:50 PDT)

Hi all,

I'm becoming quite fond of Arisaema. It started when I was a kid, growing
up in Indiana. A highlight of any spring wildflower trek into the woods
was to find Jack in the Pulpit, our native Arisaema triphyllum. Jack's
pulpit is usually green, striped with white or light green, but
occasionally you find one that is purple-brown striped with light green or
white.

I've found that the following are quite hardy here in central Indiana (USDA
cold zone 5):

Arisaema triphyllum (native here)
A. dracontium (another native)
A. ringens
A. fargesii
A. serratum
A. candidissimum
A. consanguineum
A. sikokianum

Surviving but not blooming:

Arisaema sazensoo
A. kishidae

Doubtful:

Arisaema thunbergii thunbergii
and A. thunbergii urashima

Arisaema sikokianum is the spectacular plant with the dark brown "pulpit"
and the snow white, club-shaped "jack". It is one of the early
bloomers. Many. like our native A. triphyllum, come up and bloom in
spring. There are a few that come up much later and bloom in summer: A.
consanguineum and A. fargesii, for example. The late growth habit probably
makes them much less susceptible to damage from spring freezes here.

I am looking forward to trying such species as A. heterophyllum, also
supposed to be quite hardy here. I am also starting some from seed,
obtained from the AEG (Arisaema Enthusiasts Group) seed exchange. AEG is
an electronic plant society, like Alpine-L, and resides on the same
listserver -- Surfnet.NL Go to
http://listserv.surfnet.nl/archives/… for more information.

I have a modest page for Arisaema in my own web site, and there are links
there to better pages: http://shieldsgardens.com/amaryllids/…

I grow all the species that I have in the ground, in my woodland
garden. Most of these are from China. There are tender species from other
parts of Asia that most of us cannot grow outdoors, so they are grown in
pots. I saw a couple really odd looking, unidentified Arisaema in the
greenhouses of the University of Basel Botanic Garden a year or two ago in
Switzerland. I think they were from Thailand or Burma.

The species I am aware of all grow in the summer and rest in the
winter. Winter wet may cause them to rot. I will be interested to learn
what species grow in the Mediterranean climate of the West Coast and how
the manage to survive.

Dear All,

I'm not sure what happened to the introduction for the topic of the week
this week. Perhaps it will come later in the week. I grow no Arisaemas but
know a lot of you do and that they have been mentioned a lot. And there
are many interesting pictures of them on the wiki.

So until the introduction arrives perhaps some of you can tell us which
are your favorites and why and others ask questions about them.

Thanks.

Mary Sue
