Senna artemisioides, commonly known as Feathery Cassia, is a soft-textured, drought tolerant shrub that brings a light, airy presence and seasonal color into the landscape. It’s especially valued for its fine foliage and ability to brighten dry garden palettes.

The foliage is small, finely divided, and silvery gray, giving the plant a soft, almost feathery appearance. This muted tone helps reflect light and creates contrast against darker green plants.

In late winter through spring, it produces clusters of bright yellow, pea-like flowers that stand out vividly against the silvery foliage. The blooms add a cheerful burst of color during cooler months.

It has a naturally open, slightly rounded growth habit, making it ideal for informal plantings, mixed borders, or as a soft backdrop in drought tolerant designs.

Senna artemisioides grows best in full sun and requires well drained soil. Once established, it is highly drought tolerant and thrives in warm, dry conditions.

It typically reaches about 6 to 10 feet tall and wide, forming a light, airy shrub. It is well suited for USDA zones 8 through 9, however it is also seen thriving here in Southern California which is why we have included zone 10. The foliage is evergreen to semi evergreen depending on climate.

This plant has low toxicity and is generally safe for gardens with pets and children.

The flowers attract pollinators such as bees.

It is generally deer resistant.

Senna artemisioides fits especially well into Mediterranean, desert, and Australian-inspired garden designs, where its texture and seasonal color can be used to soften and brighten plantings.

It pairs well with plants like Leucophyllum frutescens to reinforce a silvery palette, Grevillea ‘Firesprite’ to add vibrant flowering contrast, and Lomandra ‘Breeze’ to introduce a structured, grassy texture.

Expert Tip:

Place this in full sun with excellent drainage, because it performs best in dry conditions. Light pruning after flowering will help maintain a more compact shape and encourage fresh growth.
