CASSIA renigera

Cassia renigera is a tropical tree similar to Cassia nodosa, but the flowers are more showy and a richer pink.
The tree produces bunches of bright pink flowers that cover the tree almost entirely. Grows quickly.

Prefers a humus rich soil in a moist soil in a protected sunny position, drought and frost tender.

Grow notes:

Although seed can be sown most of the year in many parts of 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.
