Growing senna multiglandulosa from seed

Senna is a prolific producer of seed and is quite easy to grow.

To prepare the small, hard brown seeds for sowing place them in a cup and pour near boiling water over them and allow to stand over night. The seeds should swell and soften and will now germinate quite quickly.

Plant the soaked seeds into containers or trays with a well draining mixture. As a weedy pioneer plant, senna does not require a highly fertile soil and young plants will sprout and grow in a sandy soil.

The plants, especially when young, are sensitive to frost. Once established the trees can withstand light frosts.

Details  Senna multiglandulosa is a species of flowering plant in the legume family known by several common names, including glandular senna, downy senna, and buttercup bush.

It is native to Mexico, Guatemala, and western parts of South America, but it is widely cultivated as an ornamental plant and in some areas of the world has become naturalized in the wild. In some places it is considered a weed, for example, in New Zealand and New South Wales.

This is a hairy or woolly shrub which can grow to six meters in height, becoming treelike. The leaves are each made up of several pairs of thick, hairy, oval-shaped leaflets each measuring up to about 4 centimeters long. The leaves are studded with visible resin glands between the leaflets. The inflorescence is a raceme of several flowers, each with five golden yellow petals measuring 1 to 2 centimeters long. The flower has seven fertile stamens with large anthers and three sterile staminodes. The fruit is a legume pod, flattened or inflated and coated in hairs, reaching up to 12 centimeters long and filled with beanlike seeds.
