chiming in here re: Erythronium...

I've had excellent germination with *Erythronium revolutum* + *Erythronium
oregonum* by collecting seed after pods open (typically mid-June at sea
level Vancouver, BC); I keep inside for the rest of summer; within paper
seed envelopes, inside an airtight glass container, packed with dry short
grain rice, located a cool but non-air conditioned basement (avg. 21c). I
sew into damp by v. well drained medium within an airy-greenhouse typically
in late september or early october, and with this method seem to have very
good success. this method generally follows the macro-phenomena of their
seasonal cycle, ie. keeping them close to evolved temperature conditions in
their habitats, but keeping them guarded from being eaten up or rotted
away. the lack of diurnal fluctuation within the basement doesn't seem to
have any negative effects on germination...

hope that helps 🐇

That's really interesting, Diane. I wonder if that is why my
Alstroemeria seeds germinate best after being kept at room temperature
until fall sowing?

Erythronium, along with other spring blooming flowers, sheds seeds
with undeveloped embryos. They need months of warm weather for the
embryos to develop within the seeds. Putting them in the fridge will
halt that development.

Off hand the only old bulb seed I’d be leery of offering is
eryththronium. In my experience they don’t seem to like storage but
maybe I’m not storing them correctly. If anyone has further
information on the subject of erythronium seed storage I’d like to
hear it.

Jane,

I find that Alstroemeria germinates well with 6 weeks at 70 F (20 C)
dark, and then transfer the ones not sprouted to the refrigerator at 40
F (4 C) till they sprout.
