Dark Purple Caralluma
Caralluma Stalagmifera is also commonly known as the ‘Dark Purple Caralluma’. As the plant matures it can reach around 40 cm (16″) tall. The branches from the stem are mostly brownish to reddish but they can become 60 cm (2ft) long and around 2 cm (0.8″) in diameter. The leaves are star shaped and red. The plant flowers produce tiny, star-shaped dark purple flowers that have yellow tips.
Calalluma plants prefer early morning or late afternoon sun. They will require much water and soaking the pots. They will tolerate very hot weather outdoors as long as they are kept in filtered light and this will encourage them to flower in the Autumn. They also enjoy some fertilizer.
As soon as they are flowered be sure to take extra precautions to keep them dry, because damp cool conditions when the plants are resting is an invitation to fungal infections
Since roots are quite shallow, use a cactus mix or add extra perlite or pumice to regular soil potting soil. A gritty, very free-draining compost is suitable, and clay pots help the plants to dry out between watering. Re-pot every 1 year.

For watering cacti, the golden rule is to make sure the soil is completely dry before watering! This will stop the roots from rotting. It is advised to always use a pot with a drainage hole so that excess water can get drained out. If kept in a sunny area, you will need to water it once every week. If it is in a semi shaded or filtered light area, you might need to water it once in 2 weeks.
Cacti like soil that is well aerated and fast draining. You can fertilise the cactus in the summer months when it is in its growing season. During the winters it is best to cut back on any fertiliser and let the plant rest.
