Senna obtusifolia

Java-bean (Senna obtusifolia) is a medium-sized evergreen shrub featuring yellow or orange pea-like flowers. This shrub is native to tropical regions of the world, such as Australia, Brazil, China, India, and Southeast Asia. Because of its dense branches, it is often used as an ornamental hedge or for screening purposes. The leaves are dark green, thick and waxy, with several pairs of leaflets making them look like feathers. In the winter months tiny seed pods form when the flowers dry up, giving the shrub a multi-dimensional look. Java-bean prefers loamy, well-drained soil and can tolerate drought and frost. This evergreen is an excellent choice for a low-maintenance landscape.

watering

Java-bean plants should be watered regularly, with deep soakings about once a week. Water less often in winter and more often in spring and summer when the plant is actively growing. Avoid over-watering, which can cause root rot and other problems. Be sure to never allow your plant to sit in soggy, water-logged soil. Water your java-bean early in the day so that the leaves have time to dry before nightfall.

sunlight

Java-bean (Senna obtusifolia) is a plant species native to the Caribbean and South America that prefers full sun to partial shade. The plant requires a minimum of 4 to 5 hours of direct sunlight every day and does best when the temperature is between 65–80°F. It is best to avoid midday sun in the hotter months as the intense heat might burn the leaves. During the colder months, the plant can tolerate more sun and should be moved outdoors if it is in a container indoors.

pruning

Java-bean (Senna obtusifolia) should be pruned annually in late winter or early spring, when temperatures are mild and the threat of frost has passed. Pruning should be done conservatively, removing no more than 1-third of the plant's overall growth. Before pruning starts, remove all dead or damaged branches and plants from the area. Pruning should create an open structure, allowing for sunlight and airflow to reach all parts of the shrub. When cutting branches, cut just above a node; this creates a stronger callous and encourages proper healing. Pruning can also help keep the plant from becoming too top heavy and leaves the unique shape of the Java-bean plant intact.
