Basella alba - Malabar Spinach - Basellaceae

Basella alba, or Malabar Spinach, is a very fast growing vine native to Tropical Africa to Asia. Vines will reach 30 feet (9.1 m) long in one growing season. Dark green, fleshy leaves are broadly ovate to 5 inches (12.7 cm) long. Malabar Spinach is planted in the tropics as a potherb or substitute for spinach. It has an agreeable flavor and can be eaten raw or cooked. I like to use the leaves on sandwiches. They are interesting plants to grow, are of easy culture, and make a great tropical looking vine in the landscape. Plants are hardy in USDA zones 10-11.

Blooming: Plants in the greenhouse bloom almost non-stop. The inflorescence is a simple spike in the axils of leaves. The small pinkish white flowers are followed by hard black seeds.

Culture: Basella alba will grow in full sun to partial shade and prefer a rich moist soil mix. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 2 parts loam to 1 part sand or perlite. We add 1 cup of 14-14-14 Osmocote to the soil mix for every 0.01 cu yards of mix. The soil should be slightly acid with a pH of 6.5-6.1. The plants are well watered and allowed to dry slightly before watering again. We fertilize the plants monthly with a balanced fertilizer diluted to ½ the strength recommended on the label. In containers, the plants can get out of hand fairly fast; we cut the vines back twice a year. During the winter months, fertilizer is withheld and watering is reduced but not to the point of causing leaf dieback.

Propagation: Basella alba is propagated by cutting and from seed. The hard black seeds germinate best if soaked in water overnight and sown. Seed germinate quickly in 7-14 days after sowing.

Basella alba was featured as Plant of the Week February 1-6, 2008.
