oleander and periwinkle. It is not related to true Plums, which are members of the Rose
Shrub or small tree.
1-3' high and 3-6' wide, depending on cultivar. In its native region, some varieties grow
White, five narrow, thick waxy petals, 2" diameter, with a fragrance similar to jasmine and
Spring and summer. In some regions, plants will bloom and display fruit most of the year.
Yes. It may need hand pollination.
Years before fruiting:
Red, plum-shaped, 1-3" diameter, with 6-16 small seeds. The entire fruit is edible when ripe,
tasting like sweet cranberries, strawberries or raspberries, depending on the degree of
ripeness. There is a latex overtone to the flavor because these plants have not been bred to
lose latex from their ripe fruit.
Months for fruit to ripen:
3. The fruit is ripe when it is pink or red, not green, and is slightly soft to the touch.
These fruits ripen individually and not all at once. They persist on the plant after ripening.
Storage after harvest:
One day at room temperature, no more than one week refrigerated. The fruit do not ripen
further once picked.
Glossy dark green, thick, oval, smooth margins, often overlapping.
Thornless or Y-shaped double spines, milky latex sap if broken or cut.
Fibrous, extensive, non-invasive.
The flowers attract pollinating insects. The fruit attracts birds and mammals in its native
Toxic / Danger:
All parts, except ripe fruit, are mildly toxic. Spines are present on most cultivars.
The Natal region of South Africa.
Cultivation and Uses
USDA hardiness zones:
9b-11. Young plants need protection below 30°F. Established plants survive 25°F.
If its roots are well mulched, and this plant dies to the ground in a freeze, it will come
back from its roots mid spring.
Full sun to part shade. Most cultivars sold in nurseries today do best in part shade.
Locate this plant in full sun in well draining soil. It can be grown in a container.
Well drained, tolerant otherwise. This plant does better in pH 6.1-7.5 (slightly acidic
to neutral) soil, and is tolerant of salinity.
In soil with a low organic content, apply organic fertilizer mid to late winter before new
Water after becoming established:
weekly to monthly depending on the size
of the fruit crop and temperature. Deep water monthly in winter. The soil must dry out between
waterings. This plant is subject to root rot in wet soil.
Apply organic mulch to shade the root area from summer heat and winter freezes.
First Year Care:
Water every day or two to establish an extensive root system. Do not overwater.
It is often pruned into a narrow hedge to make its fruit more accessible, or to serve
as a barrier. After the last frost, remove any dead or damaged branches. Flowers appear
on new growth.
Cuttings, layering, seed. Seeds are variable in germination times and may not breed true.
Ornamental, edible fruit, barrier hedge. The fruit can be used raw in salads or cooked into
jams and pies. Cooking removes latex from the fruit, but do not cook in aluminum cookware
because the latex particles will adhere to the sides of the pan.
Prostrate varieties are useful as erosion control on mild slopes.
A former scientific name is Carissa grandiflora.
The most common cultivars sold in nurseries are low shrubs and groundcover
plants, both with small thorns.
Another closely related shrub is Carissa carandas: Carandas Plum.
