The deciduous lewisias, especially rediviva, do very well here in full sun with some protection from excess summer moisture under the garage eaves. I've got a bunch of L. cotyledon seedlings from Ron Ratko seed and would appreciate advice on siting them here in SE PA - particularly with respect to amount of sun they will take and how much moisture they would like in the summer. Always on the scrounge - I'd also love seed of Lewisia tweedyi if anyone has any spare. I have one plant outside that seems to be doing well but the others rotted off. I think I have a better feel for what they need now. Thanks, J.
