It’s called self-seeding, which is how these rather spectacular Euphorbia characias Wulfenii appeared in my garden a couple of years ago, from a nearby plant on the bank behind.
I probably wouldn’t have chosen it for this spot as it’s such a large plant, but after all it’s hard work germinating itself in a crack in the paving, I decided to let it grow. Given how good it looks, I’ll probably use it like this in a future planting plan next to a terrace, if the opportunity comes along.
Euphorbias are perennials from a huge group, this one originates from Greece, which gives a clue about its preferred growing conditions. It has a bold architectural shape with blue-green leaves present all year round.
Like all plants, given the conditions it needs, generally it’s origins will inform about these, it will flourish ….. simple really.
Plant it in a light, sunny spot in well drained soil and it will reward you with these beautiful lime green flower-heads in early summer. The unseasonably hot weather at the moment has fooled it into thinking it’s summer already.
Cut the flower-heads back to ground level as they fade, but take great care as the milky sap is an irritant to eyes and skin.
Height 1m x spread 1m.
Have you got the right conditions to grow this in your garden?
