Euphorbia ‘Copton Ash’

Euphorbia

Milkwort

Named after Euphorbus, physician to the king of Mauritania, this robust, sun-loving genus in­cludes the familiar Poinsettia and is over 1600 species strong. Most Euphorbia have a poisonous milky sap and soft-colored bracts that surround subtly defined flowers. Autumn watches many of their narrow green leaves turn shades of red, orange and yellow.

<i>Euphorbia</i> ‘Copton Ash’

Honoring plantsman Kent Copton, who developed both a garden and a nursery in Faversham, England, this well-groomed shrubby Euphorbia produces finely hewn cool bluish green foliage and billowing masses of lime-green flowers in an endless summer procession. Compared to E. ‘Dean’s Hybrid’ or E. ‘Blue Haze’, its needle-like linear leaves are longer, while its larger semievergreen mound surpasses E. ‘Limewall’s. For a lovely floral pairing, ‘Copton Ash’ can be planted with Geranium sanguineum var. lancastriense along a pathway, amidst rock work or in a planter.

Blooms May–October

Size: 2' 0" high x 2' 0" wide.
