Senna coronolloides is a sprawling shrub that can grow to 2m in the wild.
Flowers are held in axillary racemes on long stalks (peduncles 3-12cm long) with 3 to 5 golden-yellow flowers per peduncle.
APS members found it at Bolivia Hill and propagated it. The plants are usually found in woodland environments under trees - in mottled shade. Its range is usually to the west on slopes and tablelands of NSW, but this population has been verified growing here.
Plants can often be purchased from the
Mole Station Native Plant Nursery and the Armidale Tree Group nursery.

Se_coronolloides plant

Senna coronolloides has grown to about 50cm high in our garden - in full sun. The seed pods (legumes) form quickly.

flower heads

Leaves are compound, parapinnate, green and the pinnae are elliptical with an obtuse or mucronate tip. They make a great texture in the garden.

Flowers are held in racemes and have bright golden-yellow petals.
A raceme is a simple arrangement where each flower has a stalk and the end bud is the youngest flower.


Legumes are green ageing to brown. The black seeds need hot water treatment for germination to occur. This treatment is common for all legume plants.
Also, all legumes will fix atmospheric nitrogen in the soil, thus improving the soil as they grow.

This wonderful plant is a gem for small gardens. It spreads quickly to a width of 1.5m or 2m.
Ours were quick to thrive and flowered profusely from spring to autumn. The frost did not affect them adversely other than the leaves closing up overnight, and they continued to grow slowly over winter.

APS members have noted that specimens grown in full sun will maintain a more compact shape, but may die after a few years. Ours have been growing well for 18 months in full sun.

Most Senna sp in Australia are back in the Senna genus after being named Cassia sp for many years. Senna coronolloides also grows in Queensland.

Senna coronolloides is a great plant for quick results in dryer beds where it flourishes easily.
After a short settling in period,they have coped with the coldest days but need some water in the hottest times in our garden.
