Thuja standishii × plicata 'Steeplechase' Arborvitae
‘Steeplechase’ arborvitae is a narrower form of the bigger ‘Green Giant’ hybrid arborvitae. It has a far more dense, fuller habit, with foliage more feathery and finely cut. It is dense to the tip, unlike its ‘Green Giant’ parent. It is both more narrow and shorter growing than ‘Green Giant’. This is great screening coniferous evergreen for limited spaces.
Best grown in moist, fertile, well-drained soils in full sun to part shade. Tolerates somewhat wide range of soils and some dry conditions. Best in full sun, but generally appreciates some light afternoon shade in hot summer climates. For screens, plant trees 5-6′ apart. Plant trees further apart for other uses.
