Euphorbia is grown for its blooms, which open in summer. It's hardy across USDA zones 4 through 8, shrugs off deer and shrugs off dry spells. Its summer flowers are a moderate draw for honeybees and native bees.

Start the season right
Plant euphorbia in full sun.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match euphorbia's needs before planting.
Water steadily
Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut euphorbia blooms in the cool of the morning, just as they open, for the longest display.
Good to know
One caution for pet owners — euphorbia is toxic to dogs and cats (mild severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
Euphorbia offers moderate value to bees and other pollinators.
