What Is This Plant With Blueish-Green Leaves?

Ask the Expert: Please can you help me identify this plant?

Euphorbia characias wulfenii

Hi, I walk past this garden every morning on the way to work and have watched this plant since mid-summer grow quite vigorously. I really like its look and would like to plant some in my own garden. But having searched through my RHS encyclopaedias and the Internet, I have failed to identify it. Do you have any idea what it it? The highest stems stand around a foot high and it is a slightly blueish-green in colour with a white strip running down the centre. Any help will be very much appreciated. Many thanks, John

I had a good idea that the plant was some kind Euphorbia, but I need a little help to make a positive identification.  Lucky for me the great guys at the Memphis Botanic Garden came to my rescue.  The plant is mostly likely a Euphorbia characias wulfenii other wise known as Mediterranean Spurge. In full sun, this clump forming perennial produces chartreuse flowers.

Now that you know the name of the plant, you should be able to find it at a local garden center.

Flower Shop Network tips it’s hat to Rick Pudwell at the Memphis Botanic Garden for the help in identifying this plants.  Thanks Rick!
