Caesalpinia decapetala seed

LATIN NAME: CAESALPINIA DECAPETALA

COMMON NAME: Mysore Thorn

The Mysore thorn sparks the large, scrambling, thorny shrub with the twice-divided leaves of the many small, green leaflets and the dense, upright clusters of the many small, bright-yellow flowers that open through the warm season, the clusters sparking along the prickly, arching stems, the flat, brown pods following. The plant scrambles quickly through the open ground, and it stands the heat and the dry spells well. It likes the sun, and the well-drained soil.

Scientific Research & Plant Biotechnology

The bright-yellow bloom of the Mysore thorn gives it a recognised place in the research on the warm-climate nitrogen-fixing scramblers of the Caesalpinia group, and the decapetala species appears in the studies of the traditional dye plants and the pod and wood chemistry. The work looks at the way the prickly stems build the impenetrable cover, the soil-holding habit, and the seed biology. The pharmacognosists note the traditional bark and pod uses, and the growers of the warm-climate flowering hedges keep the species in their catalogues.

Ecological & Economic Value & Wide Applications

In the warm, sunny boundary, the Mysore thorn sparks the warm garden with the yellow clusters. The blooms feed the bees, the prickly growth makes the fine, impenetrable hedge, and the roots enrich the soil. It grows well in the well-drained, sunny ground. Yellow-sparked, thorny and soil-feeding.

To grow the Mysore Thorn from seed, soak the seeds in the warm, deep bowl of water for the night, then sow them into the sandy drills of the tray, keep the tray in the warm, bright spot and water lightly.

Soak the seeds in the warm, deep bowl of water for the night, and pot the seedlings on as they grow. The spark blooms come within the season. , and the seedlings thread up within a few weeks. The spark blooms will yellow through the warm season.

Mysore Thorn is a large climber or shrub with sprawling branches, forming large impenetrable thickets, with curved thorns on young branches. The leaf spines also have thorns. Leaves are double-compound, with 3-15 pairs of pinnae, and each pinna having 5-12 pairs of oblong-elliptic, rounded leaflets, 1-2.2 cm long, 0.4-1.1 cm wide. Flowers are perfect, 2.5-3 cm in diameter, in racemes in leaf axils and at the end of branches. Petals are yellow, upper one veined or blotched with red, 1.2-1.5 cm long. Pods are, slightly swollen, 6.5-11 cm long, 2-3 cm wide, and burst open on their own. Seeds are 4-9 black, ellipsoid, laterally flattened, 8-12 mm long, 6-8 mm wide. Flowering: May-April.
