"A beautiful yellow flowering uncommon native Cassia to 15m originating from the Paluma Range area about 100km north of Townsville. It grows in monsoon forest, rainforest, vine forest, open forest and woodlands from 50m to 740m altitude.
This species displays maroon new growth which is quite distinctive.

Cassia queenslandica and Cassia sp. Paluma Range are different species. The sp. Paluma Range was thought to be marksiana at one stage, as per Floyds citing in his book of Cassia marksiana from Mt Fox- which is within the district of the Paluma Range species extent. The pods of sp, Paluma Range and queenslandica are totally different. They are totally round in queenslandica and ribbed in sp. Paluma. Also sp. Paluma has a reddish tinge to the new growth, whilst queenslandica is plain green. All Cassia species are easily grown in the garden down to at least Sydney, except marksiana which displays variable results in the vigour of plants - possibly due to poor genetic crossing within the population that the seed was sourced (often individual trees).
This tree is a spectacular bloomer leading up to Xmas and could be planted instead of Cassia Fistula - an introduced species frequently sold in nurseries.
Yuruga Nursery in North Queensland describes it as follows -
"The native cassias are so lovely compared to the commonly grown exotic species that it really is a wonder why they are not grown more often. Cassia sp Paluma Range is one of our all-time favourite plants being a neat, tidy, dense shrub with dark green tropical foliage. The large bunches of bright yellow flowers hang down amongst the leaves and branches making a spectacular display of green and gold."
