Historical Distribution

Uses and Culture

USES

PROPAGATION/CULTIVATION

  • The hard seed capsule of Abutilon menziesii is pale brown, fuzzy, and 3/8 inch long. It contains 18 to 24 small, dark brown seeds. When the capsule opens, the seeds are scattered by the wind shaking the plant. of Abutilon menziesii hybridizes with other species of Abutilon so collect seeds from plants that are distant from other Abutilon species.
  • If seeds do not shake out of the dry capsule, the capsule can be opened with a knife and the seeds removed. Abutilon sp. have a high germination rate (95%). Koob does not recommend soaking the seeds, but most other sources state that soaking shortens the germination time from 3 to 6 months for untreated seed to 2 to 4 weeks for soaked seeds. Soaking recommendations vary from 1 to 24 hours using either room temperature or hot water. Soak the seeds until they sink and disgard any floaters.
  • Sow seeds on the surface or up to 1/4 inch deep in a well-draining medium such as 3 parts #2 perlite to 1 part #4 Sunshine Mix or 1 part peat to 1 part perlite to 1 part soil. Koob suggests potting mix. Keep the medium moist but not wet and put the containers in part shade until the seeds germinate.
  • Seed should be dried before being stored. Storage recommendations vary; silica gel and refrigeration may improve the length of time seeds remain viable. Koob states that seeds in cold storage are viable for several years though they may take longer to germinate than fresh seed does. (Bornhorst 1996; Koob 2000; Stratton 1998; Wagner 1990)
  • Abutilon menziesii can be grown from cuttings, but it is difficult. (Koob 2000)
  • Abutilon menziesii can be grown by air-layering. (Bornhorst 1996) [Data from Herring, E. C., & Criley, R. A. (2003). The Hawaiian Native Plant Propagation Web Site: Developing a Webbased Information Resource. HortTechnology, 13(3), 545-548. https://www.ctahr.hawaii.edu/hawnprop/]

Notes

  • 200-520 m
  • A collection from an abandoned cane-field at 'Ewa, O'ahu, made in 1981 probably represents an escape from cultivation
  • At that time all cultivated plants were descended from the Puako, Hawai'i, popula-tion; this population was later destroyed by cattle during an unusually dry year. More Recently the Lāna'i plants were brought into cultivation. Hillebrand (1888) recognized a Lydgate Collection from Lāna'i varietally (B), but no distinction is made here, although specimens from Lāna'i have densely pubescent calyces, pale corollas, and large mericarps. This species has been federally listed as endangered It is also known as Ko'oloa'ula
