Overview
Green Gem Boxwood is a compact evergreen hybrid with fine glossy foliage and a naturally rounded outline. It gives formal beds and small entries year-round structure while staying lower and tighter than many traditional boxwoods.
Mature Size and Habit
Expect a dense mound about 2 to 3 feet tall and wide. Growth is slow, and old plants may become slightly broader when left untrimmed.
Best Landscape Uses
Use it for low hedges, geometric borders, foundation accents, knot-garden structure, or large containers. Repetition works well along entries and walkways when plants receive good air circulation.
Sunlight
Morning sun with afternoon shade is the safest exposure in Tampa. Full sun is suitable with steady moisture, while deep shade leads to thinner growth.
Soil, Drainage, and Irrigation
Plant slightly high in well-drained soil. Water deeply through establishment, then allow the upper soil to begin drying before the next irrigation. Avoid low wet areas, buried crowns, and irrigation that keeps foliage wet overnight.
Best Planting Season for Tampa and Central Florida
Install from October through early spring so roots establish during cooler weather. Summer planting demands closer moisture and heat management.
Pruning and Maintenance
Clip lightly after new growth hardens, or thin selected branches to keep light inside the shrub. Sanitize tools between plants. Watch for boxwood mites, leafminer, scale, Volutella, and root rot in poorly drained beds.
Wildlife Value
Small spring flowers offer limited pollinator value, and dense branches provide modest shelter for small wildlife.
Cold and Heat Sensitivity
Green Gem tolerates ordinary Central Florida cold, but intense afternoon heat and reflected sun may bronze or scorch foliage. Warm wet soil creates the greatest long-term risk.
Safety, Roots, and Placement Warnings
Boxwood is toxic if eaten and presents a pet concern. Roots are shallow and competitive but not usually destructive. Keep plants away from edible beds and provide clearance from hot pavement.
Invasive Concerns
This hybrid is not native to Florida and is not generally treated as invasive. Remove volunteer seedlings if they develop beyond the intended planting.
