Acacia farnesiana Seeds | Sweet Acacia
LATIN NAME: Acacia farnesiana
COMMON NAME: Sweet Acacia
Plant Profile
A distinctive member of its genus, Sweet Acacia (Acacia farnesiana) is a spreading shrub, native to tropical America. Sweet acacia gilds feathery, evergreen branches with small, round, golden-yellow flower heads through winter and spring, twice-divided leaves holding soft, ferny green, and the whole plant carrying the warm, scented look of the tropical acacias. Flowers open in dense, fragrant globes, each with sweet, heady perfume, and dark, woody pods follow. Bush grows into thorny, spreading shrub or small tree, and it stands heat and drought well. Its appeal to pollinating insects adds a second, ecological layer to its ornamental one. Few species give back so generously for so little effort.
Science & Biotechnology
Seed science, comparative botany and horticultural selection all touch on Acacia farnesiana, a representative of the Acacia group with clear practical value. Sweet acacia has a long, perfumed record in aromatic-plant research, and cassie scent has kept perfumers busy for generations. Because it has been grown for so long, its garden habits are thoroughly documented.
Uses & Benefits
Sweet Acacia works well in borders, containers and dedicated beds. In warm garden, sweet acacia perfumes winter months. Golden, fragrant heads open through winter and spring, heady scent carries across garden, and blooms draw bees and the butterflies. Sweet acacia seeds need quick treatment with hot water before sowing, poured over and left to cool, which wakes hard seeds. It takes hold quickly and asks for no special treatment from then on.
Acacia species have a rich practical pharmacopoeia: gum arabic from acacia sap is a globally used demulcent, emulsifier and soluble fiber, while bark decoctions rich in tannins have served folk medicine as astringents for centuries.
Growing from Seed
Seed is the natural starting point for Sweet Acacia, and the process is uncomplicated. Scatter the seed evenly over a loose seed compost, cover to no more than its own depth, and keep the pot moist and bright. Shift the seedlings into small pots as soon as they can be handled, and give them bright light until planting-out time.
Our Take
Among the Acacia group, it is one of the more distinctive species in cultivation. The medicinal tradition behind this species, outlined above, is a large part of its interest. Attention to moisture in the first weeks pays off; later, the plant is forgiving.
