Family Crassulaceae
Subfamily Crassuloideae
Genus Crassula
Species rupestris
Common name(s) Tom Thumb
Crassula rupestris is an easy "plant and forget" succulent, thriving as an indoor or outdoor plant. Once established, it is hardy to long periods without water as an indoor plant (though a bit happier with regular watering, if it's getting wrinkly it needs a drink!). The pads can take on a reddish stress coloration.
This crassula variety is fairly brittle, with stems easily snapping during handling and repotting. Half the reason this one is available for sale is because I periodically knock a few parts off the parent plant and pop them in a new pot. The plant usually already has fine air roots poking out from between pads—just poke broken stems back into the pot and they will root themselves. I find this crassula to be relatively slow to grow and branch anyway, so this method will give you a fuller-looking plant.
Options: The "parent" plant you will receive a cutting from is pictured. Options are a rooted or "unrooted" cutting (unrooted will usually have air-roots).
