Plant details

Euphorbia characias subsp. wulfenii is an architectural perennial, perfect for adding a touch of drama to the border. Bluish-green foliage looks fresh all year round, and in early summer it's joined by large, dome-shaped, lime-yellow flowers that tower above it. It's ideal for growing in a sunny border or gravel garden, and is a good planting partner for kniphofias, which bear orange and yellow flowers. 

For best results grow Euphorbia characias subsp. wulfenii in moist but well-drained soil, in full sun. Cut down the flower stems to ground level as the blooms fade. Be careful when handling the plant as the thick, white sap can irriate the eyes and skin.

This is a really hassle free plant that gives fantastic drama and a zing of citrus colour to your border. I planted a small one a year ago in a hot sunny border with poor,dry soil. Despite being fried in the sun and covered in snow it has survived, thrived and tripled in size! It looks great with grasses and red / orange roses or other flowers.
