Euphorbia Acrurensis.

Cowboy Cactus.

Native to South West Africa.

Full sun to part shade, or indoors well lit. Can tolerate a harsh, windy environment.

Rarely. Around once a month in the spring and summer and may only need a drink every two to three months in the autumn and winter. Use the soak-and-dry method. Use your fingers to ensure the soil is completely dry before watering. After watering profusely, make sure the soil drains completely before watering again. Too much water, or water that is not fully drained, can cause the Cowboy to rot.
