Boxwood and summer snowflakes in New Orleans
The Beuregard-Keyes House in the New Orleans' French Quarter boasts immaculately tended hedges and a stunning ornamental garden.
For centuries, boxwood (Buxus spp.) has been a key element of many parterres — flat, symmetrical designs that look two-dimensional when seen from above. Parterre design can be as fancy or as simple as you like.Skip to next paragraph

Tight, low boxwood hedges enclose planting beds packed in early February with summer snowflakes (Leucojum aestivum) on one side and red brick paths on the other. The garden’s focal point, located in a brick circle at the center of the parterre, is a cast-iron fountain from which the surrounding beds radiate.
I love how colors play off each other in the BK winter garden. Red brick walls and paths unify the vertical and horizontal planes, making the complementary green boxwood edging stand out. Multiple shades of green create winter color patterns. The blue-green foliage of leucojum contrasts with the boxwood’s bright yellow-green new growth, a pairing echoed in the dark green shutters and yellow walls of the house.
In the Zone 9 climate of New Orleans, leucojum blooms in winter, but elsewhere it blooms in early spring. It multiplies freely and tolerates both summer drought and swampy clay soils.
Leucojum, an old-fashioned bulb of the sort you’d see in your grandma’s garden, produces white bells with pea-green dots near the tips of the petals (tepals, actually). The cultivar ‘Gravetye Giant’ is sturdier than the species, with bigger flowers, and grows 24 inches high.
If you let common boxwood, B. sempervirens, grow naturally, it becomes a small, twisty tree with multiple trunks. At the BK house, sheared boxwood forms tight hedges. Common boxwood is hardy in Zones 6-8, with cultivars such as ‘Vardar Valley’ and ‘Variegata’ hardy to Zone 5.
Littleleaf boxwood, B. microphylla, is by nature a dense rounded three- to four-foot shrub that's hardy in Zones 5 to 9, with cultivars such as ‘Green Mountain’ and ‘Green Velvet’ hardy in Zone 4.
No matter which boxwood you grow, it will need regular shearing to maintain a tight, formal look. Easily sculpted, it adapts beautifully to topiary and hedging, either straight or with baroque loops and interlaces.
