Outstanding Qualities

This handsome perennial is among a palette of Mediterranean plants well-adapted to the coastal Pacific Northwest climate, which receives much rain in winter and has extended dry spells in summer and fall. Euphorbia characias subsp. wulfenii 'John Tomlinson' is a dramatic plant that grows into a large robust plant. In late winter to early spring great club-like inflorescences emerge from the crown. Bright chartreuse flower-like bracts glow in the garden 'John Tomlinson' was selected for particularly large flowers with an intense color. The overall effect is eye-catching and lasts well into June. At about the same time, new shoots emerge holding narrow, grey-green leaves. The whole plant reaches three feet tall and wide, so it makes a perfect focal point for a bed with well-drained soil and full sun. It combines well with perennials like blue oat grass, giant needle grass, maiden grass, bear's breeches, stinking hellebore and digger's speedwell. Plant it with such shrubs as smoke bush, purpleleaf barberry, Ceanothus 'Victoria', Rosa glauca and bay laurel. This statuesque plant is a striking addition to any garden.

Culture Notes
This euphorbia grows best in well drained soil in full sun. It is drought tolerant once established. Shoots emerge one year, bloom the next, and then die. The trick to keeping this plant going is to remove the flower shoots at the base once they are no longer attractive without damaging the new shoots that have begun to grow. Be careful and wear gloves when removing stems because the white sap in the stem can cause skin irritation. Seedlings are freely produced, but they can be pulled easily when young.
