Ivory Silk Lilac Tree

Ivory Silk is a compact Japanese tree lilac with a rounded crown and showy early-summer flowers. Its creamy-white panicles are fragrant, and its dark green leaves and reddish-brown bark provide structure beyond the bloom period. ## Flowers and form The [Ivory Silk profile](https://www.gardenia.net/plant/syringa-reticulata-ivory-silk) describes clusters 6–12 inches long, a rounded crown, and flowering that begins while the tree is young. It gives a mature range of 20–25 feet tall and 15–20 feet wide. The [Morton Arboretum’s lilac guide](https://mortonarb.org/plant-and-protect/trees-and-plants/japanese-tree-lilac/) also identifies Ivory Silk as a more compact Japanese tree lilac. ## Siting Plant in full sun for the strongest flowering; light shade is tolerated. Average moisture and well-drained soil suit it, and the profile lists clay, loam, sand, and chalk among suitable soil types. Use it as a specimen or near a foundation where its mature size has room. ## Maintenance Prune as needed immediately after flowering. Keep good air circulation around the crown, and water during prolonged dry weather while the tree establishes.
