The Japanese tree lilac is a stunning ornamental tree prized for its elegant appearance and fragrant blossoms. Its deciduous foliage consists of ovate to elliptic leaves that emerge in spring with a fresh green hue, transforming to vibrant shades of yellow in the fall, creating a striking contrast against its smooth, grayish-brown bark. In early summer, the tree bursts into bloom, boasting large, creamy-white panicles of flowers that exude a sweet, delicate fragrance, attracting pollinators and admirers alike. This tree typically grows in a broad, rounded form, making it an excellent focal point in gardens or landscapes.
