BOLUSANTHUS speciosus

A fast-growing good-looking and reliable tree with gorgeous weeping wisteria like violet blue fragrant flowers. Wispy weeping foliage and rugged textured bark.
The weeping, blue-mauve perfumed pea-like flowers hang from the branches in bunches, often covering the whole tree. Flowering occurs during spring and early summer. 

Native to South and East Africa.

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

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 3-4mm deep keep warm & moist but not wet.
4. Germination should occur in 10-21 days @ 18-22C.

General note: Seeds of many species 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.
