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 species have a poisonous milky sap and softly colored bracts that surround subtly defined flowers. Autumn watches their narrow green leaves turn shades of red, orange and yellow.

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.

Stellar blue flowers that deer forego, water-thrifty and other deer-proof plants!

These deer-proof perennials...

offer a variety of blue flowers that lend eye-catching intrigue to the landscape or a bouquet. 

More deer-proof plants plus favored water-shy selections...

Many of our customers frequently ask us to suggest plants that are undaunted by either deer or dry conditions. In this newsletter, we’ve featured a diverse group of plants, including not only perennials, but a handful of grasses and shrubs as well. Many selections boast steadfast temperaments, while others offer blooms that are long-lasting, late-blooming, pollinator-friendly or tailor-made for arrangements. And all are brimming with good looks, which goes without saying!

Please note: A plant’s deer-tolerance depends on the locale, the particular herd, the time of year, plus the recent weather conditions, especially rainfall. The ability of a plant to endure dry conditions varies with sun exposure, humidity and soil type.

Happy Digging!
