Euphorbia Ingens

Light: Full sun to light shade; afternoon shade is beneficial in Phoenix, especially for young plants. Acclimate gradually to intense desert sun.

Water: Low water once established; water deeply, then let soil dry thoroughly. Reduce watering sharply in winter and avoid watering before freezes.

Soil: Very well-drained, sandy or gravelly soil. Use raised planting areas where drainage is poor and a gritty cactus mix in containers.

Mature size: Typically 20–30 feet tall and 10–15 feet wide in favorable frost-free landscapes; potentially taller. Usually smaller in containers or Phoenix’s frost-prone locations.

Bloom: Mature plants may bloom in fall to winter; flowering is uncommon on young or container-grown specimens.

Evergreen / deciduous: Evergreen succulent stems; tiny, short-lived leaves are usually absent.

Growth rate: Moderate; faster with warmth and appropriate summer watering, slower in containers or cool weather.
