Lisa,
If you see anything on Rick Lupp's list, let me know. I may be down there
in the next week or 2, and would gladly pick up whatever you were
interested in and mail them on.
What are gardening friends for?
Rick

Lisa may be mixing up the two sorts of Lewisia species, the evergreen
and the deciduous.

I know in the summer they go dormant. Would I just entirely skip

during this time would be ok?
The commonly grown L. cotyledon and L. tweedyi (which has been under
discussion) are evergreen. Tweedyi goes semi-dormant in winter. Some
species, such as L. brachycalyx, L. nevadensis, and L. oppositifolia,
are summer-dormant. They do not have "tubers." The storage organ is
an enlarged, partly underground stem known as a caudex. In many but
not all species, these caudexes (or caudices) multiply as the plant
ages, and it can be lifted and propagated by division.
I have always grown the deciduous species with my summer-dry bulbs,
under cover, but I planted some L. nevadensis seedlings on the rock
garden a couple of years ago, and they are flowering this spring.
Evergreen species in the Pacific Northwest should be planted where
there is extremely good drainage, such as in a pocket of a dry stone
wall. Some people have good success with L. tweedyi west of the
mountains (it is native east of the Cascades, in a much drier area)
by planting it within the drip line of a large conifer.
