Family: Rutaceae
Agathosma betulina, commonly known as Buchu, is a flowering plant native to South Africa. It belongs to the Rutaceae family and is known for its aromatic leaves, which have been used for centuries in traditional medicine and herbal remedies. The Buchu plant is a small evergreen shrub that grows up to 2 meters in height. It has small, leathery leaves that are rich in volatile oils, giving them a strong fragrance reminiscent of blackcurrant. These leaves are the main part of the plant used for medicinal purposes. This species has a limited distribution in its native range and is not known to be naturalized or invasive anywhere in the world. Although it could spread locally through its dehiscent seeds, and resprouts after fire, it is unlikely to have detrimental impacts in the Hawaiian Islands.
High Risk Traits:
- Reproduces by ballistically dispersed seeds.
- May reach maturity in 2+ years
- Seeds dispersed by ballistic dehiscence, by ants, and through intentional cultivation.
- Resprouts after fire.
Low Risk Traits:
- No reports of naturalization or invasiveness, but limited evidence of introduction outside native range.
- Unarmed (no spines, thorns, or burrs).
- Non-toxic
- Grows best in high light environments (dense shade may inhibit spread)
