Sort:  

Yes it is silly. The form with the pubescent leaves is low-growing, a little like Adromischus umbraticola

Ooh, umbraticola is high on my want list!
I think I'll put this Crassula in my garden, they make great-looking clumps over time

They are almost like a miniature form of Cotyledon orbiculata although of course Cotyledon flowers are very different and designed for sunbirds

Swaziensis flowers are nothing like the Jade-type flowers: they are born in little bunches on stalks

They will look very good in a rockery
