Greyia sp. or Natal bottlebrush is an attractive evergreen shrub or small tree native to South Africa. Grown in USDA Zones 9 to 11, Greyia sp. can reach heights of 5 to 10 feet, though with adequate support it can attain heights of 10 to 20 feet. Full direct sunlight is necessary for the plant to thrive, as well as regular waterings. Greyia sp. has showy, dense clusters of deep scarlet flowers that bloom in upright racemes. It is highly attractive to butterflies and hummingbirds.
For those who live in colder climates, Greyia sp. can be grown in pots, as long as it is adequately sheltered from the cold and brought indoors to a warm environment during winter. In either case, direct sunlight is necessary and regular watering is essential. If temperatures fall below 40 degrees, it is recommended to bring the pot indoors to avoid damage to the plant.
Greyiasp. is not only an attractive addition to any outdoor space, but has a long history of medicinal properties and is a valuable healing plant. Growing and caring for Greyia sp. is a straightforward task, thus making it the perfect choice for those wishing to add some color and traditional medicinal benefits to their garden. Selected species include Greyia radlkoferi, Greyia flanaganii, and Greyia sutherlandii.
