Hi out there! I just bought a Lewisia cotyledon, for WAY too much money, but it was GORGEOUS! And I'd never seen or heard of it before. I see it belongs to the purslane family, but am finding conflicting info online. Can anyone tell me if I can grow this indoors, and should I use a soil mix for succulents! I don't have rock garden, but hope to develop an indoor succulent garden. We have a humid-ish climate here on PEI, and I don't have southern or western light in the house. Any hints would be greatly appreciated!
