How to grow Popcorn Cassia (Senna)

Cassia grows best in full sun and moist, well-drained soil. Plants flourish in the heat and humidity of summer. Water regularly and use a balanced, water-soluble fertilizer (such as 20-20-20), mixed and applied as directed, to promote lush growth and flowering.

Cassia is generally pest free and deer resistant.
