Feathery Cassia (Senna artemisioides)

Another possibility for mine and my neighbors Southern California gardens. I have seen this out in the Palm Springs area where my sister has lived for 20+ years and it does look very attractive as part of a xeriscape environment. I am not sure if I have enough sun here in my garden, but there might be a couple of areas where it would fit. According to the Wikipedia page it can grow up to 3 meter, which might the a little large for some gardens. I don’t think I have ever seen it grow this large in the gardens where i have seen it, though.

“Blunt-leaved Senna” (and spelling variants) redirects here. This name is also used for Senna obtusifolia, a large shrub common in warm humid regions.

Senna artemisioides is a flowering plant in the family Fabaceae. It is commonly known as Silver Cassia or Feathery Cassia – although “cassia” generally refers to the largest-growingCassiinae. Some of its distinct subspecies also have common names of their own. This plant is endemic to Australia, where it is found in all mainland states and territories, except forVictoria.

This is a shrub that grows up to 3 metres in height. It has pinnate leaves with between 1 and 8 pairs of leaflets. It produces an abundance of yellow flowers in winter and spring which are about 1.5 cm in diameter, followed by 2 to 7 cm long flat green pods which age to dark brown.

The species adapts to a wide range of climatic conditions, although it is susceptible to frost, particularly when young. It prefers dry, well drained sites with full sun. As an ornamental plant, it is propagated readily from seed, which should first be soaked in boiling water.[1]

This plant has gained the Royal Horticultural Society‘s Award of Garden Merit.[2]
