A cute little euphorbia with tons of offshoots. The new growth has red spikes. These are not pokey, but they will secrete a sticky white sap if they are damaged.
Your plant will be similar to the one in the photos.
Part sun, protect from hot afternoon sun
Let dry between watering, water deeply
Not as picky about soil, store bought succulent mix is good, especially if you add some sand or perlite/pumice to make it drain a little better
Ships in a plastic pot with soil.
