  Re: [aroid-l] juvenile vs. adult

Dear fellow (I coudn't find your name in the message),

Here follows my contributions to your question. Probably you will get
much more then this.

1) Does this happen only to vining aroids?

Nope. Noticeable changes in leaf form also occurs in terrestrial tuberous
plants. Leaves in Taccarum warmingii are triangular hastate when young, then
it has pinatelly compound leaves. Spathantheum usually have a cordate leaf
when young, that are usually deeply incised in mature plants. Sometimes,
adult plants can even keep cordate leaves. However, I think that most of the
incredible changes occurs in vining aroids, like shingle plants (Monstera).

2) Besides lots of light, does this also require lots of heat and numidity?

I can see no direct relationship, but if you have more heat and
humidity, you plant will grow faster! In my experience, if you give a good
support for the growing plants (i.e., a totem or a nice tree), it will
change from a juvenile plant to an adult plant, whatever the time it takes.
I really think that the presence of a stem attached to the substrate is more
important than the light. Climbing plants growing with full sun, but no
totem, usually will not yield adult stems.

3) So can this be done indoors under home conditions without a greenhouse?

Yes, if you have enough light and a proper totem to climb. Room enough
as well!
