We love mix and match plants…those versatile subjects that work in a variety of garden compositions. We think Euphorbia x ‘Blue Haze’ qualifies as such. In fact, I’m trying to think of plant colors that wouldn?t coordinate with this plant, and I can?t. The powder blue foliage subdues the tone of the lime green bracts just enough to work well with pastels, yet still allows the vibrant chartreuse “flowers” to shine and support stronger color complements as well.
Grow Euphorbia x ‘Blue Haze’ for summer bloom as well for its nearly evergreen (for us) glaucous foliage. A Plant Haven introduction, it?s a cross between E. nicaeensis and E. sequieriana subsp. niciciana and presents a tidy accent for the front of the border or even as a container subject. The loose 15″ mounds spread to about 2′, and the somewhat decumbent stems bear limey bracts from June through September. It loves dry sites, and enjoys full sun or partial shade. Deer won’t touch it because of its caustic sap (be careful if you have sensitive skin). Reports on hardiness vary. We can attest we’ve had successful experience overwintering ‘Blue Haze’ in zone 6a, but a number of nurseries list its hardiness to zone 5 (-20F). As is true of so many plants, good drainage is the key. Report to us if you’re a cold climate gardener who’s had success with this plant.
