About Christmas senna
Senna bicapsularis, commonly known as Christmasbush or Sencillo, is an evergreen shrub or small tree native to tropical America. It is characterized by its abundant, bright yellow flowers that appear in clusters during autumn and winter, creating a vibrant display. It is ideal for tropical or subtropical gardens, informal hedges, or as a specimen plant, adding a splash of seasonal color.
Native range
Tropical America, from southern Florida and Mexico to the Antilles and northern South America.
Care tips
It prefers full sun exposure for optimal flowering, although it tolerates some partial shade. It requires regular watering during its growth and flowering period, reducing it in winter; it is tolerant of short dry spells once established. It thrives in well-drained, fertile, and slightly acidic to neutral soils. A common mistake is planting it in areas with severe frosts, as it is not tolerant of them.
