Senna surattensis seed
Golden Cassia or Glaucous Cassia is a shrub or a smallwith clusters of bright yellow flowers. Cassia surattensis typically reaches a height of 15 feet and develops a rounded dense crown and silver gray bark. Leaves are green, even pinnate, 4-10 x 1 1/2-3 inches, with 6-10 pairs of leaflets, but without a terminal one. Leaflets are oblong-elliptical, 3/4-1 3/4 x 3/8-5/8 inches. Flowers are borne in upright clusters at branch ends and nearly cover the canopy with faintly fragrant yellow blooms about 1-1 1/2 inches wide. Bees and butterflies visit the flowers. Fruits are pods, flat, brownish when mature, 3-6 inches long, splitting open to release 4-15 flat seeds. These are used for propagation. This tree can be grown in a range of well-drained soils; it requires vigorous pruning and is short-lived and easily toppled by wind and needs staking for 2-3 years after planting. In landscaping, this flowering tree can be a specimen or accent tree in gardens, along roads and in parking lots, and in a butterfly garden.
