Posted by Pat: I'm having difficulty germinating
jack-in-the-pulpit seeds. I filed the seed coat before I
soaked them, but they haven't come up.

Char: Jack-in-the-pulpit is easy enough to propagate. The
female plant produces a cluster of green berries, which turn
to red in autumn. You can plant the berries, or just scatter
them in a rich soil (in partial shade) with lots of leaf
litter for new plants next year.

Bruce: The seeds should have been damp and never allowed to
dry out, and have been refrigerated for at least three
months prior to planting inside. If these conditions were
not met, then the seeds have gone into a deep dormancy and
it may be several years before they germinate. If they
received the proper treatment, they could take up to month
to germinate (mine took about three weeks, but they all came
up).

nancy brown: I gathered the red seed head and left it on a
cold porch for the winter. In the spring, I scattered the
seeds around a fairly damp and shady area, so I assume quite
a bit of moisture is required for germination.

Louise z5 MI: I've planted them immediately in the fall with
excellent success. They haven't flowered yet though; in two
years. Maybe this year.
