Arisaema seedlings grow slowly.
I have 3 species grown from seeds (A.
consanguineum, A. serratum and A. concinum).
They are 3 years old and they are
about 10 cm tall and the same diameter.
I cultivate them in my garden, they
put leaves up in the late spring and go dormant in autumn.
Here are links to two of
In some species the first leaf is
entire, in other it is already 3- or more sect, there's no rule.
Also there's no rule how old they
must be to be adult.
A. flavum usually blooms in the third
year, but most species need more time.

Subject: [Aroid-l] Question on Arisaema
seedling growth and care
these Arisaema seeds that I am trying to grow. I potted them in a
peat, soil mix and placed them under some lights (I dont have a yard or
anything). The lights are a bit stronger than the light you see in
So far this season I have gotten two seedlings to
germinate since sowing in August. One looks normal to me, while
the other has the triphylum morphology already.
So my question
is, why does this seedling look like a second year growth? Could
it be that this is one of my, what I thought to be, failed seedlings
from last year that went dormant over the summer?
Or could an
Arisaema first year seedling have this morphology?
I was told last year that I was supposed
to give these seedlings a cold rest period when dormant. Is 50 F
good enough? Should I wait until this years growth dies on its
own? Or should I expose them to the cold temps forcibly? If
so, these leaves just came out, how long should I let the plantlets
