Paeonia seed germination, was Paeonia californica

Jane,

That's really true that it takes two yeas to see leaves. I tried to grow
this peony many times, but unfortunately they did not make it. Again I
received seeds of P. cambessedessii and other Mediterranean peony seeds
from the Mediterranean Garden Society (seeds exchange program from Southern
France) and PBS two years before. This early winterI many seedlings popped
up from unexpected pots.

To answer Dylan's question about Paeonia cambessedesii: I grow a lot of
this species, as well as other ones. I never scarify the seed, even the
massive seeds of P. lutea, which self-sows in this area. Generally no leaf
appears the first year after sowing, but a radicle is produced (known as
hypogeal germination). The leaves appear the second spring. This seems to
be a consistent pattern. Other species peonies also self-sow in gardens
here, particularly P. daurica.

Most of my P. camb. seeds come from two plants I keep in the bulb house
(planted directly in the bed, not in pots), but some seed obtained under
that name from the NARGS seedex germinated this spring and contained mixed
species or hybrids; only one appeared to be true(ish). P. camb. is easily
identified by its almost metallic blue-green leaves, very beautiful in
early growth. It was not quite winter-hardy in my former garden (up in the
hills), but I think I'll try some outdoors now that I'm at a lower
elevation. It will certainly be a wonderful plant for California gardens,
ornamental both in flower and in foliage. It goes dormant in late summer.
In the bulb frames and bulb house it has survived about 20 degrees F when
covered from rain.

When I worked at Rancho Santa Ana Botanic Garden we had a crop of P.
californica. I remember the seeds germinated like kidney beans without any
treatment, but getting them through their leafless summer dormancy in pots
was challenging. Watering lightly about every two weeks helped during this
period; seedlings kept totally dry perished. The mix was well-drained with
plenty of sand and pumice and a low % of organic matter. Still, after a
few
years we ended up with only one plant in a 1x1x1 foot wooden box.

Recently I planted fresh seeds of P. cambessedesii with zero germination
over winter. The seeds appear to have a harder coat that the CA native
species. Maybe they need scarification as someone else mentioned?
