Growth—

Mesembryanthemum crystallinum is not very hardy in the temperate zone and will be killed even by a light frost[1]. It is, therefore, usually grown as a half-hardy annual, being sown in a greenhouse in the spring and used for summer bedding[2]. Easily grown in an ordinary well-drained garden soil[3, 2]. Succeeds in any well-drained low-fertility soil, including saline soils, so long as it is in a sunny position[4, 5]. A very ornamental plant, it is occasionally also cultivated for its edible leaves[3, 1, 6]. This species uses the 'Crassulacean Acid Metabolism' (CAM) pathway to photosynthesis, a mechanism which aids in conserving moisture. The plant keeps its stomata closed during the day, opening them during the night when it takes in carbon dioxide and stores it in compounds such as malic acid. It then utilizes this carbon dioxide when photosynthesizing during the day. This type of mechanism is used by a range of mainly succulent plants, including cacti and Euphorbia species. In climates with mild winters, the plant can flower all year round[6]. Plants have few problems with pests or diseases though the young plants are prone to root rot and damping off unless given plenty of ventilation and dry growing conditions[4].

Propagation

Seed - sow spring in a greenhouse, only just covering the seed. When they are large enough to handle, prick the seedlings out into individual pots and plant them out after the last expected frosts. Seedlings are prone to damp off so should not be over watered and should be kept in a very sunny well-ventilated position[4].
