The flowers of this species are more of a salmon pink than the other Cassias and each petal is delicately veined with green, the pink becoming deeper as the flower ages.

The bracts at the bases of the flower stalks are pale green and the calyces pink. Each leaf bears from five to ten pairs of small leaflets, oblong and blunt ended.

Native to East India.

Prefers a rich moist well-drained soil in a protected sunny position, drought and frost tender.

Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C.

Cassia seeds germinate readily, however they do have a hard outer coating which is impervious to water and generally germination will normally not occur unless the seed is scarified by abrading or pre-treated with boiling water first.

  1. Place the seed in a container and pour in just boiled water and allow to soak overnight.
  2. The swollen seed can then be sown, re-treat seeds that have not swollen.
  3. Sow the depth of seed keep warm & moist but not wet.
  4. Germination should occur in 10-21 days @ 18-22C.

General note: Seeds of many plants are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
