The Story

Plant Bio

Boxwoods are broadleaf evergreen shrubs highly valued for their small leaves, dense growth habit, and tolerance of heavy shearing, making them the quintessential plant for formal hedges and topiaries. 'Glencoe', sold as Chicagoland Green®, is a hybrid boxwood developed by the Chicago Botanic Garden for its exceptional cold hardiness and its ability to retain its deep green foliage color through harsh winters with minimal bronzing.

EarlyLate

Uses & Benefits:

Chicagoland Green® provides the classic, fine-textured, deep green foliage that makes boxwood a staple of formal garden design. Its naturally rounded, yet spreading habit creates a full, lush appearance, and its ability to stay green in winter provides essential year-round structure and color.

This cultivar's primary practical use is as a low, formal hedge that defines garden spaces, edges walkways, or creates intricate parterre designs. Its exceptional cold hardiness extends the range where reliable, green boxwood hedges can be grown.

The small, inconspicuous spring flowers provide an early source of nectar for bees. The dense evergreen structure offers valuable shelter and protection for small birds from predators and harsh weather, especially during the winter months.

Planting

How to Grow

Select a site with well-drained soil, preferably with afternoon shade.
Amend soil with compost to improve drainage and fertility.
Dig a hole twice as wide as the root ball and just as deep.
Gently tease out circling roots before placing in the hole.
Ensure the top of the root ball is level with or slightly above the soil.
Backfill, water thoroughly, and apply a thin layer of mulch.

Pro Tip

Plant in a location protected from harsh winter winds and afternoon sun to prevent winter burn and ensure best color.
