1″ blooms are borne in October-November on this large arching tree-like shrub or root hardy perennial. The Winter Cassia may freeze to the ground in the northern portions of its range but it is quick to return in spring. A host plant to Sulphur butterflies and nectar source for a variety of pollinators. Sometimes called the Butterfly Bush or Christmas Senna, this durable plant is considered to be somewhat drought tolerant once well-established and is deer resistant.
Growth Habit: Woody Shrub, 8-12ft tall by 8-10ft spread
Native Origin: India, Asia
Hardiness Zone: 8-10
Environment Needs: Full Sun, Part Shade
Growth Rate: moderate
Maintenance: Fertilize yearly in Spring. Cassia makes an easy-care addition to beds, borders and butterfly gardens. Grow cassia in well-drained soil that isn’t prone to standing water. Can be grown in a container.
Warning: Winter Cassia has the potential to reseed and may be considered invasive in certain areas. Deadhead to prevent reseeding.
