Grewia robusta (Raisin Bush) is a large shrub or small tree native to South Africa. It typically reaches heights of 5-10 ft tall and grows in full to semi-shade. This plant is drought tolerant but will perform best with regular watering. The blooms are a stunning pink color, making it a great choice for attracting hummingbirds and butterflies to your garden.
Plants are mature and cold hardy at least to the mid-20sF for a short time and can be grown in USDA zones 8-10. If you live in a colder region, you can still take advantage of this plant by growing it in a pot and taking it indoors when the temperature drops. Pot grown Grewia robusta will require a loamy soil with good drainage and protection from severe cold weather. It is also important to monitor the soil's moisture, ensuring that it is kept at adequate levels throughout the cold months. Additionally, you may need to consider adding an extra layer of mulch to protect the roots from the cold.
Overall, Grewia robusta is an easy to care for plant with stunning pink flowers and edible fruit. This makes it a great choice for gardeners looking to add an exotic touch while still requiring minimal care.
