Carissa bispinosa, commonly known as Forest Num-Num or Y-Thorned Carissa, is an evergreen shrub or small tree native to a variety of habitats including coastal forests, bushveld, and riverine thickets from Uganda to South Africa. It typically grows up to 16 feet (5 meters) in height and features a dense, rounded to spreading form. The plant is adorned with fragrant white flowers that bloom sporadically throughout the year, with a peak in spring and summer. These blossoms are followed by attractive, round, red fruits that are edible when ripe and have a sweet taste.

Forest Num-Num is valued for its ornamental qualities, including its glossy, dark green leaves and the contrast between its fragrant white flowers and red fruit. It is often used in cultivation for hedges, screens, and as a security plant due to its thorny branches. It thrives in full sun to partial shade and prefers well-drained soils, tolerating a range of soil types. While it is drought-tolerant once established, moderate watering is recommended for optimal growth. Carissa bispinosa is also known for its low maintenance requirements and resilience to pests and diseases. However, it is potentially invasive in some regions outside its native range and should be planted with caution.CC BY-SA 4.0
