Blue Haze is a hybrid herbaceous Euphorbia with bright chartreuse-yellow flowers in late spring. Its bright blue, evergreen foliage is equally ornamental. This sterile selection thrives in poor soils and hot, sunny growing conditions.
6-8" tall x 12-15" wide. This dazzling spring bloomer's electric, chartreuse-yellow flowers will light up any hot, sunny flower bed. When the flowers are done, the equally outstanding powder-blue, evergreen foliage will hold your interest year-round. 'Blue Haze' has a semi-spreading habit and is ideally planted in patio containers or in the front of the perennial border. A sterile hybrid, this is an excellent substitute for Euphorbia mysinites, an invasive species in the Western US. Plant 'Blue Haze' in your poorest, fastest draining soil, where it will always look good! (Cutting grown.)

Tips For Growing Euphorbia (Spurge)
Euphorbia (Spurge) is a huge genus of annual, perennial and succulent species that can be found worldwide. All Spurge have milky sap that can be very irritating to eyes, nose and mouth tissue. Some species have poisonous sap. Handle with care. Rabbit and deer proof. Preferred growing conditions:
Plant in a fast draining, infertile soil with full sun. Avoid clay soils. Mulch with gravel or not at all.
Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
Deadheading recommended to prevent re-seeding, as some species can spread aggressively. Use gloves to protect hands from irritating sap.
Fertilize lightly in the fall with Yum Yum Mix.
Succulent species have evergreen stems. Prune to shape in the spring if needed.
Cut back herbaceous species in late fall.
