Brush Cassia can be a spectacular tree when in bloom. It is similar to the Golden Shower Tree (Cassia fistula) of street-plantings but has smaller leaves and darker flowers. The golden-yellow summer flowers are fragrant and hang in large clusters from the fresh, lime-green foliage. Brown, cylindrical fruits, which develop in winter, are segmented and contain hard yellow-brown seeds, each enclosed in a cardboard-like envelope. The tree may grow to 25 m tall but most are 5 – 10 m. Defoliating caterpillars often give it a scruffy look.


The Brush Cassia occurs north of Brunswick Heads, around Murwillumbah, and into south-east Queensland as far as Beenleigh.
