Euphorbia consists of a large variety of plants which can be annuals, perennials, shrubs or succulents. They ll have milky sap which can be irritating to skin, and small unusual flowers held within colourful bracts.
The plants are hardy enough for all areas of the UK, and can be grown in any soil except clay as long as it is well-drained. Siting can be made in any site including deep shade as well as sheltered or exposed places.
Propagation can be done in spring as the plant spreads by rhizomes, however it should be kept in check as it can become somewhat invasive in good growing conditions.
If pruning, the plants can be cut back to ground level in late summer or autumn.
