Encephalartos lehmannii, commonly known as the Karoo cycad, is a species of cycad in the family Zamiaceae. It is native to South Africa, particularly the Eastern Cape Province. This plant is known for its striking blue-green leaves and is often used as an ornamental plant in subtropical gardens. It has a natural dormancy period during the cooler months.

Ensure the plant is kept in a well-ventilated area with moderate humidity. Water sparingly, allowing the soil to dry out almost completely between waterings.
土壤
This plant prefers sandy soil with excellent drainage. A well-draining cactus or succulent mix can be used. Avoid waterlogged conditions as they can lead to root rot. The soil should be slightly acidic to neutral.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10 during the growing season. Fertilize sparingly, as over-fertilization can harm the plant. Apply fertilizer once every two months during the active growth period.
