An eye catching shrub with yellow buttercup flowers inside which are curly stamens. The flowers are borne in large sprays and stay in full bloom for a long period. When not in bloom the plant remains attractive due to its fern like leaves.
Native to South America.
Prefers a light to medium 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.
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.
