Lewisia
They germinate well either started indoors under lights or wintersowed. If wintersowing-add gravel to the bottom of the jug.
Once you pot them up put them in a pot that has gravel on the bottom. They don't like to be wet but can somewhat tolerate it.
Do not plant out the year they germinate! Leave them in a pot for one year. If under lights they may bloom indoors. You can also overwinter in a pot in a greenhouse or cold frame/alpine house.
When planting make sure you add lots of rocks/grit to the planting hole. Likes alpine conditions (sharp drainage) best although they are more tolerant than some. Add a layer of rocks around the neck of the plant to keep the leaves dry.
Warning*-squirrels ate half of a plant I had planted in my backyard. Not sure why (looking for a corm?). The plant hung on for a bit but eventually died. Do what you can to discourage them!
