CROTALARIA benthamiana

An attractive small shrub with alternate and narrowly oblong or wedge-shaped that produces spears of bright yellow pea-like flowers most of the year in its natural range.

Occurs naturally in the Pilbara region of Western Australia.
Easy to germinate and will grow successfully in most temperate to hot climates.

Recently renamed Crotalaria dissitiflora subsp. benthamiana

Prefers a light well-drained soil in an open sunny position, drought and resistant to an occasional frost.

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 in temperate climates, avoiding the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C.

Cortalaria seeds germinate readily, however, they do have a hard outer coating that 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 and the leaf appears in 10-21 days @ 18-22C.

General note: Seeds of many natives 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.
