Phonetic Spelling:STYE-racks juh-PON-ih-kus

Genus:Styrax

Species:japonicus

Family:Styracaceae

This deciduous flowering tree exhibits a relatively compact growth habit, often taking on a vase shape in its youth, but developing a broader, rounded crown with age and featuring low, horizontal branches. It thrives in moist, acidic, well-drained soil and prefers full sun to partial shade, casting a gentle light shade. The tree shows moderate tolerance to salt. It produces blooms in late spring, with fruit maturing by late summer. The foliage is primarily located on the upper branches, allowing the pendulous flowers to remain visible. The bark is characterized by irregular, interlacing orange-brown fissures, adding visual interest to winter landscapes. This tree is ideal for planting on hillsides or slopes, though it requires consistent moisture. It can be positioned near patios, in lawns, along borders, or in small clusters. For optimal growth, consider planting it on the northern side of a building to shield it from strong winds while providing delightful dappled shade for other plants beneath it. However, it does not cope well with heat or drought conditions.
