Euphorbia polygona is a spiny suŃculent with simple or basally clumping, gray-green stems with beautiful "heads" of dark purple flowers. The stems are up to 5 feet (1.5 m) tall and up to 4 inches (10 st) in diameter. The fruits are globose with gray hairs and up to 0.2 inches (0.5 cm) in dianeter.
When spring arrives, the plantâs only demand is moist soil. Water the plants deeply and thoroughly when rainfall is less than 2 inches per week. Keep up the watering schedule as long as the plant is growing.
This low-growing plant tolerates partial shade to full sun and a variety of soil types, and it requires almost no maintenance.
It is toxic to animals and humans, but where this is not a concern, it offers the benefit of being virtually immune to feeding by deer and other wildlife.
