    Well-armed, durable succulent Euphorbia. Tends to branch low down instead of growing a tall main stem. This behavior is especially apparent in seedlings. Seasonal growth pattern, almost all in spring and summer, but very fast when given space and water. Nice yellow flowers. Plant may be self fertile.
