Outstanding Qualities

Wheel tree was once found only found in collectors' gardens, but it is gradually becoming more widely available. It is a lovely tree that produces a single main trunk from which are carried a whorl of horizontal branches, somewhat like the spokes of a wheel. Its evergreen leaves are long and tapered, and their bright green color contrast well with rhododendrons and the trunks of our native conifers. Planted as single specimen, it is eye catching due to its distinctive growth habit. It grows well in open woodland settings with Daphne odora 'Aureomarginata', Elaeagnus pungens 'Maculata', Fatsia japonica and Sarcococca hookeriana var. humilis. Consider underplating it with groundcovers like hellebores, Pulmonaria 'Benediction', Pulmonaria longifolia ssp. cevennensis and cyclamen.
