Dodecatheon seed
Steve Marak via pbs (Tue, 08 Feb 2022 20:03:07 PST)

I can speak only for the local Dodecatheon meadia, which I think has
been moved to Primula, but it's viable for at least several years with
room temperature dry storage. Here (NW Arkansas) it's a plant of the
prairie remnants and occasional spring damp hillsides, bluffs, and
glades - nothing in deep shade, and usually very dry and hot in summer.

The prairie form here is exclusively white flowered, and very attractive
in the spring with the flower heads floating over the emerging grasses.

According to J. L. Hudson, Dodecatheon seed has a 10-year half-life.
Jelitto seems to have pretty reliable & timely restocking though (I've
emailed them to ask about some of their short-lived/hydrophilic seed) so
you're probably good either way!

Dear All,

The pictures of Dodecatheon wet my appetite (Thank you very much,
Robert) and I found out that they would be perfectly happy in my
climate and on my lime free soil. Somehow the shooting stars never
crossed my mind as garden plants. I checked with Jelitto and they offer
some species which are summer dormant. If I would order now and sow in
autumn, is that advisable? Is the seed long lived enough to still
germinate in autumn? Or better take the chance and hope that fresh seed
will be on offer later? I have no experience at all with this genus and
do appreciate your advice and experience.

Thank you very much

Uli
