New and Under-Utilized Asian Trees for North American Gardens

Abstract

The growth characteristics and horticultural merit of eight Asian trees that are generally unknown in North American horticulture are discussed. Seven deciduous trees (Sorbus hupehensis 'Pink Pagoda', Sorbus pallescens, Acer tschonoskii var. rubripes, Acer carpinifolium, Dipteronia sinensis, Heptacodium miconioides, Rehderodendron macrocarpum), and one conifer, Taiwania cryptomerioides, have been observed for several years at the University of British Columbia (UBC) Botanical Garden in Vancouver, to determine their suitability for more widespread cultivation as street, park or garden trees.
