Euphorbia 'Blackbird' is an evergreen perennial with a compact, bushy growth habit. It grows to about 18-22" tall and 22-24" wide. Its outstanding feature is the exceptionally dark purple velvety foliage which contrasts strikingly with the large clusters of yellow-green flowers that bloom in late winter/early spring.
Plant 'Blackbird' in a spot where it'll get sun for at least half the day. If it's too shady, the leaves will turn dark green rather than deep purple.
Blackbird's tolerant of most soils including clay, both dry and moist, as long as they drain fairly quickly. It doesn't like being in waterlogged soils for prolonged periods.
Blackbird tolerates the heat of California's central valley and will survive winter temperatures down to 0°F.
Once established, Blackbird euphorbia is fairly drought tolerant. On the coast, it'll survive normal summers with no supplemental water, although it does look better with an occasional deep watering about every 2-3 weeks. Inland, we suggest a deep watering every 2-3 weeks. Blackbird will tolerate more frequent watering if necessary. If you have hard water, try not to wet the leaves when you water as it'll leave white stains on the dark foliage.
Euphorbia 'Blackbird' is a hybrid and was discovered as a sport of Euphorbia 'Red Wing.'
Deer and rabbit resistant.

When the flowers are looking messy, cut off the whole stem near the base of the plant. Remember to wear gloves when handling this plant. If you get the sticky white sap on your skin, wash it off straight away. Don't touch your face if you get the sap on your hands. Go the emergency room if you get the sap in your eyes.
