Propagation
Sow fresh seed during spring and maintain a temperature of 19º to 24º C. (66º to 77º F).

Take stem cuttings of non-flowering shoots during the growing period.

Botanic information
Leaf: The brown areoles contain reddish-brown or black spines that are arranged with up to 7 radials and 2 thicker centrals. They appear on the edge of the stem ribs.

Flower: The large whitish funnelform flowers appear during the night on the old growth of the plant and normally towards the top during summer.

Fruit: The yellowish naked berry is tinged in red and is very viable. The seeds are viable but the plant may be reproduced vegetatively.

General cultivation
Outdoor Cultivation
In warm regions with low humidity, cold and frosty night’s cacti and succulents grow well outdoors. The more humid atmosphere will limit the number of successful species. All of these plants require a very well drained soil and ample sunlight to succeed. Once established these plants require minimal maintenance.

Indoor Cultivation 
Cacti and succulents grow well in glasshouses or near a sunny window with some ventilation tolerating a marked difference in day and night temperatures.
Cacti have a rest period during mid winter when they can be stored in a cooler area with reduced watering, once every two months. Protect the plants from freezing temperatures or extreme direct hot sunlight behind glass. All plants prefer a period outdoors during summer.

Watering
These plants normally have wet and dry periods. Watering should take place during the growing period of the plant. When new growth appears water well once a week and never water if the soil is already wet or place the pot in a saucer of water. Free drainage is essential for a healthy plant and succulents rot easily in moist humid conditions.

Problems related to watering.
Overwatering succulents results in leaves that wilt and discolour or stems that rot.
Under-watering results in a sudden loss of leaves or brown and dry spots on the leaves. Leaves also fall if the water is too cold.

Pots
Both clay and plastic pots are suitable. The pot should fit the plant comfortably and not be too big as it may remain moist, rotting the plant. Water only when the soil has dried.
Re-pot only when necessary in to a slightly larger pot for older plants. If the plants are very large replenish the surface soil and thoroughly water.

Desert cactus that are woolly or spiny use a potting mix of equal parts of sterilised loam, shredded sphagnum peat and gritty washed sand with the addition of one part limestone gravel all chips to assist in strong spine formation. (Never use powdered lime or chalk)
