What are the horticulural aspects of Euphorbia helioscopia?

Euphorbia helioscopia grow best in well-drained soil and full sun to partial shade conditions. They thrive in zones 3-9 and can tolerate a wide range of temperatures. Watering should be moderate, allowing the soil to dry slightly between waterings.

When planting sun spurge, choose a location with good air circulation to prevent disease. Plant the stems in late spring or early summer, spacing them 12-18 inches apart. Water thoroughly after planting and keep the soil consistently moist until the seeds germinate. Use a balanced fertilizer at planting time.

For optimal harvesting, cut back the stems in late summer to encourage new growth and prevent seed dispersal. Harvest seeds when the capsules are fully ripe and split open, revealing the seed. Cut off the seed capsules, dry them, and remove the seeds for sowing or storage. Sowing should be done in late winter or early spring.
