Buxus

Boxwood

Developed at Ontario’s Sheridan Nursery, this handsome open-pollinated cross between Buxus sempervirens and Buxus microphylla var. koreana is a match made in heaven that melds the best traits of both parents: diminutive compact size, superb cold hardiness, dense vigorous growth and rich forest-green winter hues. The tight-knit, naturally broad mounding habit is neatly dressed with small, gleaming opposite leaves. Undaunted by deer, shearing and hot humid weather, aptly named ‘Green Velvet’ makes a low edging shrub, posh container specimen and a classic dark green addition to borders, parterres, knot gardens and massed plantings. Mulch, good drainage, dappled afternoon shade in hot environs plus an annual thinning for improved air circulation promise long-lived evergreen growth.

Size: 3' 0" – 4' 0" high x 3' 0" – 4' 0" wide.

Hardy to zone 5.

Hallmarked by a well groomed verdure, the low growing ‘Green Beauty’ is second-to-none for hedging or edging, accenting the rock garden or making an architectural statement just about anywhere. Polished, small rounded leaves maintain a crisp, dark green look all year long while cloaking the upright, yet compact semidwarf form.

This versatile evergreen can handle hot and cold weather and makes a plucky counterpoint amid Westringia ‘Smokey’ or Teucrium fruticans (Select Form).

Size: 4' 0" – 6' 0" high x 4' 0" wide.

Hardy to zone 6.

Applauded as one of the species’ premier forms, this good-looking chance mutation of Buxus sempervirens ‘Suffruticosa’ was discovered by its namesake in Germany’s Herrenhausen Royal Garden in the late 1980s. Hardier than other sempervirens, the distinctive dwarf habit assumes a rounded, strictly upright and compact shape with densely set small shiny evergreen leaves, sporting unique frosted blue-green hues. A dapper first-class choice for low borders, diminutive hedges, rock work and pots, ‘Blauer Heinz’ favors adequately moist, well-drained soil and requires little pruning or maintenance.

Size: 2-1/2' high x 2-1/2' wide.

Hardy to zone 5.

Introduced in 1949 by the University of Virginia’s Blandy Experimental Farm, this aristocratic evergreen Boxwood struts a suave, strongly upright narrow silhouette. Dense erect branches are clothed from the ground up with small, polished oval leaves that emphasize new springtime, soft green growth and when mature, rich dark emerald tones. A first-class choice for any garden, especially where space is limited, ‘Graham Blandy’s impeccable columnar habit can be employed as a specimen, or as a sentinel to denote a threshold, or it can be staged throughout a stylized meadow.

Size: 6' 0" – 9' 0" high x 18" – 2' 0" wide.

Hardy to zone 5.

This handsome Boxwood is distinguished by a lustrous mass of tiny dark green leathery leaves, maintaining superb winter color then transmuting a pronounced bluish cast in spring, while dressing a hardy, broad spreading habit. ‘Vadar Valley’ thrives with sun or shade, stays fairly short and rounded, grows at a moderate pace, and is the perfect choice for foundation plantings, low hedges or grouped statements, anywhere its emerald hues can shine.

Size: 2-1/2' high x 5' 0" wide.

Hardy to zone 5.

<i>Buxus sinica var. insularis</i> var. <i>insularis</i>

With a tailored demeanor clipped or not, this undemanding Boxwood is second-to-none for hedging, edging, accenting the rockery or sculpting a topiary or bonsai specimen. Young downy branches and lustrous, small elliptical leaves in crisp dark greens define the dwarf rounded form that grows slowly and a little less densely.

A reliably cold tolerant evergreen, it can be planted as a low and refined verdant border, allowing more rambunctious plants to exuberantly spill over.

Size: 2' 0" high x 20" wide.

Hardy to zone 4.

Our Featured Plant: Geranium nodosum ‘Clos du Coudray’

Gorgeous Geraniums, Long-lasting summer flowers, Saturday Strolls!

Gorgeous Geraniums!

True Geraniums are sturdy yet refined, with 5-petaled flowers borne on dainty stems above attractive, palmately divided leaves. Their spectrum of colors, from cool to electric, is rivaled only by their ability to create soft mounds and flowing carpets of lush foliage in ordinary garden soil. We plant an assortment of cultivars to always have some in bloom from spring to fall. Our hardy selections are easily grown and most will re-bloom after flowering if lightly trimmed. Be sure to browse our online selections.

Enjoy these blossoms all summer long….

Our newsletter features a diverse collection of long-blooming perennials and shrubs whose reliable flowers will grace your garden for months. These lovely blooms unfurl at the beginning of summer and continue flowering through August or September. Offering unique hues, they populate airy sprays, tall spires, blowsy flower heads or bold verticillasters. We hope you’ll find these long-bloomers as delightful as we do. 

Happy digging and happy summer from all us Digging Dog Plant Wranglers!
