Plant Type
Evergreen perennial
This plant is a perennial evergreen shrub from the Euphorbia family, known for its architectural form and drought tolerance. Like other euphorbias, it exudes a milky sap when cut, so care should be taken when pruning. It provides long-lasting structure and year-round interest in ornamental gardens.
Mature Height
90–120 cm tall (about 3–4 feet)
Euphorbia × pasteurii ‘John Phillips’ typically reaches 90–120 cm tall (about 3–4 feet) with a similar spread. Its rounded growth habit and dense foliage make it excellent for adding texture and structure to planting schemes, particularly when paired with ornamental grasses or low-maintenance perennials.
Light Requirements
Partial shade – Full sun
This euphorbia thrives in full sun to partial shade. It performs best in bright, open conditions where it can develop strong stems and compact growth. In hotter climates, partial afternoon shade helps prevent leaf scorch, while sufficient sunlight encourages healthy flowering and vibrant, evergreen foliage.
Water Requirements
Moderate
Euphorbia × pasteurii ‘John Phillips’ prefers well-drained soil and moderate watering. Once established, it’s drought-tolerant and dislikes prolonged wetness. Water sparingly in winter and more frequently during extended dry spells. Overwatering can cause root rot, so ensure the soil drains freely, especially in containers or raised beds.
Cold Hardiness
-10°C (14°F)
This cultivar is hardy to around -10°C (14°F), corresponding to USDA Zones 8–10. It tolerates mild frosts and prefers sheltered positions in cooler regions. In colder climates, protect roots with mulch or grow in containers that can be moved indoors during severe winter conditions.
