Have you noticed the small trees currently blooming with beautiful billowy white flowers? They’re Japanese tree lilacs. These small-scale trees bloom later than the more-familiar shrub-type lavender lilacs, usually flowering from about mid-June until early July.
The eventual height of Japanese tree lilac is about 20 or 25 feet tall, which classifies it as a small tree. Use in the landscape for a feature in small spaces such as courtyards, narrow side yards and close to decks and patios. Because the leafy canopy stays fairly low, they make a great screening tree between neighboring yards, or to add privacy to backyard patios and decks.
Japanese tree lilacs require little extra care. They aren’t attacked by insects or diseases. Occasionally extra shoots sprout from the lower trunk region, which should be pruned flush with the trunk.
Japanese tree lilac is readily available at garden centers. Several named varieties are common in the nursery trade including ‘Ivory Silk.’
