Bright-green leaves grow along its thick, thorny stems. Lower leaves naturally fall off as the plant ages. If your plant gets too tall and leggy, you can prune it back by half its size in spring. This will cause it to branch out. New stems will grow from below where the pruning cuts were made, making this succulent bushy and full.
Euphorbia includes annuals, perennial herbs, shrubs and trees that have a corrosive and poisonous milky sap. Many are succulent and can either be thorny or unarmed. The deciduous leaves can either be alternate, opposite or in whorls. All spurges produce unisexual flowers.
Its flowers are actually bracts that last for several weeks and are available in bright pink, red, white or yellow.
Planting and care
Take 3 in (7.5 cm) stem cuttings in spring or summer. Dip the cut ends in warm water for a few minutes to stop the flow of sap then allow to dry for 24 hours before inserting into barely moist potting mix. Cuttings will root in about 6 weeks.
Caring for Euphorbia
- Also, avoid placing the plant in an area with direct sunlight before the plant establishes a mature root system.
- It is advisable to wear gloves when taking euphorbia cuttings because the latex can cause skin irritation.
- Prune off growing tips to control plants height.
- Plants that dont bloom arent getting enough light. Move Crown of Thorns to a sunny window where it gets about 4 hours of direct sun every day.
CAUTION: Wear thick gloves when handling this plant — those thorns are sharp! Also, watch out for its toxic, milky sap, which can irritate your skin, eyes and mouth.
