Buxus x 'Green Gem'

Green Gem Boxwood

'Green Gem’ is a cold-hardy hybrid boxwood with a spherical habit. It is often referred to as being in the “Green Series” of boxwood (see ‘Green Velvet’ for more information). It is very similar in shape to ‘Green Mound’ but slightly smaller. To minimize bronzing, avoid planting in areas of direct winter sun. Deer resistant.

Comments: It was developed in Canada at Sheridan Nurseries. This boxwood has been planted extensively over the past 20-30 years. Its hardiness and non-domineering size have been popular with many landscapers.     

Uses: Small specimen, low hedge, foundation plant, edging, parterre or knot garden, containers.

Substitutes: ‘Little Missy’, ‘Justin Brouwers’, ‘Green Velvet’, ‘Green Mound’, Chicagoland Green

Green Gem Boxwood Growing and Maintenance Tips:

‘Green Gem’ should be lightly pruned in late winter or early spring to maintain desired shape. Use hand pruners or shears. Thinning is not necessary but, as with any boxwood, will help increase airflow and sunlight penetration into the interior of the plant which reduces the chance of disease.

‘Green Gem’ is very susceptible to boxwood leafminer and shows variable results in tolerance and susceptibility to boxwood blight. ‘Green Gem’ has few other pest or disease issues when planted and cared for properly.
