Care of the shrub Indigofera jucunda or River indigo |
The genus Indigofera, family Fabaceae, comprises 700 species of herbaceous plants and shrubs native to tropical and subtropical regions around the world. Some species are: Indigofera jucunda, Indigofera tinctoria, Indigofera incarnata, Indigofera decora, Indigofera gerardiana, Indigofera potaninii, Indigofera amblyantha. Common names: River indigo, Pale indigo bush, Showy indigo. This species is native to South Africa. They are shrubs that reach 5 meters (16.4 feet) in height. The leaves are pinnate (composed of leaflets inserted on either side of the petiole, like the wattles of a feather), alternate and oval. They bloom in summer with clusters of pink or white flowers. River indigo is used to form hedges, to cover walls, as isolated specimens and in bushy groups. Indigofera jucunda needs semi-shade exposure in hot climates and full sun in cooler summer regions. The soil must be well drained and contain abundant organic matter. Water moderately, waiting for the substrate to dry. In regions with hot climates, irrigation must be increased. Prune lightly in early winter to keep it compact. Fertilize in autumn with compost or manure and with mineral fertilizer in summer. Indigofera jucunda is sensitive to attack by caterpillars and mites. Pale indigo bush propagates by cuttings after pruning or by seeds sown in spring. |
