COMING VERY SOON!!
Senna ligustrina is a Florida native flowering shrub valued for its bright yellow flowers and importance to butterflies and other pollinators. It develops into a fairly upright, open shrub and works especially well in native, pollinator, and Florida-Friendly landscapes. It is also a good native alternative to some of the non-native Senna species commonly grown in Florida.
SIZE
Typically 4–8 feet tall and approximately 3–6 feet wide. It can be maintained somewhat smaller with occasional pruning.
FLOWERS
Produces showy bright yellow flowers, primarily from fall through spring, although some flowering may occur during summer. Blooming is often strongest during Florida's drier months.
WILDLIFE VALUE
An excellent butterfly and pollinator plant. Privet Senna is a larval host for several sulphur butterflies, including:
• Cloudless Sulphur
• Sleepy Orange
• Orange-barred Sulphur
The flowers are also visited by native bees and other pollinators.
Cultural Requirements
SUNLIGHT: Full sun. Best flowering and overall form are generally achieved with plenty of sunlight.
WATER: Moderate while becoming established. Once established, it is tolerant of extended dry periods and is well suited to lower-maintenance Florida landscapes.
COLD HARDINESS: Best suited to USDA Zones 9A–11. Hard freezes can damage foliage or stems, particularly toward the northern end of its range.
SOIL: Prefers well-drained soils and performs well in sandy Florida soils. It is adaptable to a range of soil pH levels and, as a legume, can perform in relatively poor soils, although additional organic matter can improve growth.
SALT TOLERANCE: Moderate salt-spray tolerance, but it is not tolerant of prolonged flooding with salt or brackish water.
GROWTH HABIT: Evergreen shrub in warmer areas of Florida with an upright to somewhat open branching habit.
Landscape Uses
Privet Senna works well as a:
• Butterfly or pollinator garden plant
• Florida native landscape shrub
• Specimen flowering shrub
• Informal border or mixed shrub planting
• Naturalized or wildlife garden plant
It naturally occurs along hammock edges and disturbed areas, making it well adapted to relatively sunny, well-drained Florida landscapes.
FLORIDA NATIVE
Yes. Senna ligustrina is native to Florida and is specifically recommended by UF/IFAS as a native alternative to invasive Christmas Senna (Senna pendula).
