Bird-of-paradise Shrub (Gilliesii)

The Bird-of-paradise Shrub (Gilliesii) is generally described as a perennial tree or shrub or vine. This is not native to the U.S. (United States) and has its most active growth period in the summer . The Bird-of-paradise Shrub (Gilliesii) has dark green foliage and inconspicuous white flowers, with an abuncance of conspicuous black fruits or seeds. The greatest bloom is usually observed in the early spring, with fruit and seed production starting in the summer and continuing until summer. Leaves are retained year to year. The Bird-of-paradise Shrub (Gilliesii) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Bird-of-paradise Shrub (Gilliesii) will reach up to 35 feet high, with a maximum height at 20 years of 20 feet.

The Bird-of-paradise Shrub (Gilliesii) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 27°F. has high tolerance to drought and restricted water conditions.
