Syringa reticulata, or Japanese lilac tree, is non-native to Ontario originating in Eastern Asia. It prefers well-drained, fertile soil, with a slightly acidic to neutral pH, with full sun to partial shade. The common cultivar ivory silk is now overplanted in Ontario, and planting is recommended only for particular sites requiring a low-profile salt/compaction tolerant tree. It should be pruned after flowering and benefits from good air circulation. Full sun is necessary for prolific flower production, and the tree attracts hummingbirds, insect pollinators, and butterflies, providing shelter and habitat for wildlife. It is considered one of the most trouble-free lilacs but should not be planted near natural areas and is currently closely monitored for emerging invasiveness. Syringa reticulata drops small seed pods and a moderate number of leaves, with the heaviest shedding in the fall. Some suitable alternatives are the Amelanchier and the Halesia carolina.
