Without much of any sign of what it's going to become, these are Echeveria colorata seedlings. They've been getting some nice growth this summer; our mild summers are actually helpful for the Echeverias. The cold and wet which will be here soon enough...that's another thing. We'll face that when it arrives.
In the meantime, we're enjoying another week or more of nice summer weather, with daytime highs in the upper 80s F (31-32 C).
