Spontaneous or accidental Euphorbia hybrids that appear as ‘weeds’ on our benches. Variable in size, shape and character, but are all nice. Most have Euphorbia milii as one parent and have spiny, branching stems, narrow to rounded leaves and red to orange or green flowers. Many form thick, gnarled trunks desirable for bonsai culture, and there have been some caudiciforms among them. No two alike.
