The story

Miracle berry grows in the forests of West Africa, where the berries have long been chewed before eating sour palm wine or kenkey. A protein in the fruit, miraculin, makes sour foods taste sweet for half an hour or so.

Planting

Part shade, acid, well-drained soil (pH 4.5 to 5.8), steady warmth and humidity. Does well in a large pot of acid mix.

Growing

Slow-growing and tidy. Water with rainwater if your tap water is hard; feed lightly.

Harvest and use

Small red berries on and off through the year; let one dissolve on your tongue, then taste a lemon.

What to watch for

Yellow leaves usually mean the soil is not acid enough.
