Natal Plum Jam (Num Num Jam)

About Natal Plums

Carissa macrocarpa – Natal plums (also referred to as Num Nums) are a wild plant that thrives in warmer weather. These are native to Natal, South Africa (hence the name), but also grow wild in warm US states, like California, Texas, Hawaii and Florida.

Their bright red fruit has a sweet and tart taste that is similar to cranberries. It has wicked thorns on it (foraging is quite the task), making it a good barrier for predators. It’s also used for fire landscaping.

Our plants are ready for harvest in October and November. They seriously make the best jam, which is also great as Christmas gifts!
