Senna alexandrina (Alexandrian senna, in Arabic عشرج or عشرق or سينامكي) is an ornamental plant in the genus Senna. It is used in herbalism. It grows natively in lower Egypt, especially in the Nubian region, and near Khartoum (Sudan), where it is cultivated commercially.
Grow Alexandrian Senna in well-drained soil that isn't prone to standing water. Senna tolerates and grows well in most moderate-quality garden soil. Provide cassia with a full six hours or more of daily sunlight. Water garden cassia approximately once a week with 1 to 2 inches of water. Do this for the first year after planting. Established plants only require irrigation during dry periods when the soil begins to dry out completely. Water potted cassia when the top 1 inch of soil feels dry. Cover the soil in the garden bed with a 2-inch layer of mulch and replenish it each fall. Mulch retains soil moisture and protects plant roots in winter. Leave a space between the cassia stem and the mulch so they aren't touching.
