Stush, It is called Royal Red Euphorbia trigona.and I kept it in the sun which really kicked the red up. I purchased it at Lowes as a 2" baby. I put it in this little boot not knowing it would get that big. I could not get it out of the shoe without breaking the plant. When I broke it an put it in a new pot it never really recovered that winter. Added that I did not water it at all it just shriveled up.
