Lisa may be mixing up the two sorts of Lewisia species, the evergreen and the deciduous. At 05:09 AM 4/13/2013, you wrote: >I know in the summer they go dormant.

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.
