Euphorbia tirucalli Family: Euphorbiaceae Common Name(s): sticks on fire Grown by: David Feix, Berkeley Shown in a container with other succulents, this plant has pencil-like stems that can be yellow to pink to bright orange. It can get fairly large, 5 or 6 feet, as a house plant, but is borderline hardy outdoors, unlike the normal green species which can survive as a large shrub outdoors in a protected frost-free site. The small leaves fall off very quickly and photosynthesis occurs in the pencil-like stems. Very drought tolerant. Photo by Steve Morse
