There's still not much going on with Lithops, only one flower is visible. But at least some other succulents are flowering. My Haworthia limifolia has grown another flower stalk and there's a seed capsule even though there's no partner plant around. The Neohenricia sibbetii is flowering since almost three months non-stop! I've counted around 40 flowers so far. Still I think it weakens the plant itself a bit.
