Utility friendly tree.
Hop bush or a'ali'i is a commonly grown shrub or small tree throughout the world with a large native range. It is indigenous to the Hawaiian Islands. Variety 'Atropurpurea' is the most colorful, with its reddish-purple foliage. It does best in full sun, in any soil, including poor and dry soils, with adequate moisture. It is also smog resistant. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'. Dodonaea viscosa has no HPWRA (Hawai'i Pacific Weed Risk Assessment).
