Spurge –

0102 ‘Blue Haze’ combines icy blue foliage with lemon yellow flowers for a real eye-popping display. Developed in England by plant breeder Robin White, this patented hybrid is the result of a cross between the species Euphorbia nicaeennsis and Euphorbia seguieriana subsp. niciciana, which are native to portions of Europe and the Middle East.

The thick, succulent, red-tinted stems of this compact, bushy perennial are encircled with linear, powder blue foliage. The leaves are evergreen to semi-evergreen depending upon climate, and may take on pink tones with the cold temperatures of winter. In spring the plants become covered with brilliant yellow to chartreuse flower heads that extend well into summer, and contrast beautifully with the sapphire foliage.

For best performance, provide ‘Blue Haze’ with full sun and very well-drained soil of average to modest fertility. Wet, poorly-drained conditions should be avoided. If desired, stems may be cut to the ground after flowering to rejuvenate the foliage. This beautiful perennial is terrific for dry slopes, rock gardens and well-drained mixed borders.

Site Selection
Plant your Euphorbia in full sun to part shade in average to rich, well-drained soil, and Euphorbia polychroma will tolerant dappled shade. Add compost or peat humus to enrich and loosen the soil if needed, but they are very adaptable to almost any soil conditions provided they are never wet. Remember to keep the soil light and airy for perennials, so cover them with loose soil and don’t pack it in after planting.

Planting Instructions
Amend your garden with compost or peat humus to enrich or loosen the soil, if needed, however Euphorbia are very adaptable to any good, loose, well-draining soil. Mix a couple teaspoons of garden food or bone meal into the planting hole if desired. Plant the roots as listed above, then water in once. They prefer a slightly dry start when they are dormant in spring and have no foliage. Once they are actively growing it is alright to give them supplemental water once a week, if needed.

Euphorbia do not require much moisture, even after they are actively growing. Early season plantings (April and May) and plants that have no foliage should be started on the dry side. During that time we like to water once and then we don’t water again until the foliage has started to emerge, then we water only rarely if the soil is very dry. They are quite drought tolerant once established.

Companion Plants
Phlox – Hot-pink creeping phlox with chartreuse cushion spurge makes an electrifying combination. After they finish blooming, both carry attractive foliage through the rest of the season.
Penstemon – Penstemon bears spikes of tubular bell-shape blooms in purple, pink, blue, or red, all of which combine beautifully with spurges in sunny borders.
New Zealand flax – The spiky foliage of New Zealand flax creates a wonderful contrast to the mounded form of spurge.
