Green Giant Western Arborvitae - 5 Gallon
- Fast, uniform privacy—naturally pyramidal evergreen built for tall screens and windbreaks.
- Quick to size up: ~25–30 ft. tall × 8–10 ft. wide in about 10 years; 50–60 ft. with time.
- Low‑maintenance and adaptable; thrives in full sun and a wide range of well‑drained soils.
- Heat‑ and humidity‑tough, with strong roots and excellent pest/disease resistance.
Green Giant Western Arborvitae (Thuja (standishii × plicata) ‘Green Giant’) is a go‑to living wall for modern landscapes: fast growing, uniform, and unfussy. Plant it in full sun where you need a dense, evergreen barrier or windbreak; it quickly forms a handsome, conical screen, yet needs little pruning (but responds well to shearing when you want crisp lines). Once established, it tolerates short dry spells and keeps its deep green color through the seasons, delivering reliable, year‑round privacy with minimal input.
Plant Description
Tall, upright conifer with a strong, pyramidal outline and dense, fan‑sprayed foliage. Naturally tidy architecture makes it a high‑impact screen that rarely needs corrective pruning.
Foliage & Habit
Flat sprays of rich green, scale‑like leaves on slightly ascending branchlets. Holds color well year‑round for a consistent, formal look in hedges and perimeter plantings.
Sun Requirements
Full sun is best (6+ hours daily) for fastest growth, densest branching, and the most uniform silhouette.
Watering Needs
Water deeply and regularly the first few seasons to establish deep roots; once established, water when the top 2 inches of soil begin to dry. Avoid chronically wet sites.
Soil Requirements
Adapts to a wide range of soil types provided drainage is good. Work in organic matter at planting and mulch broadly (keep mulch off the trunk) to conserve moisture.
Growth & Size
Rapid grower; typically reaches about 25–30 ft. tall and 8–10 ft. wide in ~10 years, ultimately maturing around 50–60 ft. tall with time when untrimmed.
Hardiness
USDA Zones 5–8; a dependable performer in regions with hot, humid summers as well as colder winters within this range.
Special Features
Easy care, strong‑rooted, and noted for improved pest and disease resistance. Uniform habit seldom needs pruning, yet accepts shearing for formal hedges.
Landscape Uses
Ideal for tall privacy screens, windbreaks, and property‑line buffers. Also effective as a stately, single‑specimen accent in large lawns or at drive entries.
Spacing & Planting
For a fast, closed screen, plant on 5–6 ft centers; for informal rows or specimen use, increase spacing to match the mature spread you want. Set the root flare at or slightly above grade.
Care Instructions
Water weekly during the first growing season; reduce frequency as roots establish. Feed in early spring. Shear lightly in late spring or midsummer if a tight, formal face is desired.
Background & Origin
A U.S. National Arboretum introduction—a selected hybrid between Japanese arborvitae and western redcedar—valued for vigor, heat/humidity tolerance, and landscape reliability.
