Japanese Boxwood is a popular hedge plant in Phoenix, and in the Southwestern USA. This popularity is justified by its resistance to heat, and to alkaline soils. When used in edge or topiary, it adapts easily to many shapes.

Cultural Practices:
Sensitives to mite and scales

Blooming Habits:
Barely noticeable flowers, in mid spring.

Fruiting Habits:

Growing the boxwood from seed is very slow. The usual way to propagate it is hardwood cuttings in winter or spring (in Phoenix, that's December-February). Cuttings under mist can be used any time.
