Interior Performance of Temperate Zone Landscape Plants
Cleyera (Ternstroemia gymnanthera), spreading lilyturf (Liriope spicata), Southern magnolia (Magnolia grandiflora), heavenly bamboo (Nandina domestica), mondo grass (Ophiopogon japonicus), climbing fig (Ficus pumila), and variegated waxleaf privet (Ligustrum japonicum ‘Variegatum ’) grown under 3 production light levels and shade-grown golden Japanese euonymus (Euonymus japonica ‘Aureomarginata’), plantain lily (Hosta ventricosa), King's Ransom Oregon grapeholly (Mahonia aquifolium ‘King' Ransom’), dwarf gold-dust plant (Aucuba japonica ‘Variegata Nana’), Wood's Dwarf heavenly bamboo (Nandina domestica ‘Wood's Dwarf’), Japanese anise-tree (Illicium parviflorum), and Pink Lady Indian hawthorn (Raphiolepis indica ‘Pink Lady’) adapted well to interior conditions following productlon. Bugleweed (Ajuga reptans) and variegated wintercreeper euonymus (Euonymus fortunei ‘Varietgata’) grown under 64% light exclusion were of acceptable quality while plants grown in full sun and under 47% light exclusion were of poor quality. Quality of Wintergreen Korean boxwood (Buxus microphylla koreana ‘Wintergreen’) grown under all production light levels was unacceptable after 15 weeks in the interior environment.
