Tender trees and shrubs with ornamental foliage and blooms belonging to the pea family, Leguminosae. Grown in warm climates or in greenhouses in cooler ones. There are about 400 varieties of acacia and are chiefly native to Australia.
Some acacias provide valuable timber, others have tannins in the wood or perfumes from the blooms. Wood is hard and durable and is used for tool handles, turnery and furniture. Acacia gums are used in dyes and in print inks and as a basis for mucilage. The blooms are edible and contain a large amount of pollen. They are also excellent trees for land reclamation where the climate permits.

|GROWING INSTRUCTIONS FOR ACACIA SPECIES|
Acacias can be propagated from seed sown in spring and summer. The seeds are hard and must be scarified (scratched or chipped) and soaked in warm water for 24 hours prior to planting. Sow them 1/2 inch deep in pots or trays filled with a sterile potting medium or equal parts of peat moss and sand. Cover with glass or plastic to hold in the moisture. When the seedlings appear, remove the cover and allow them to grow on until they reach about 2 inches in height. They can then be repotted in 3 inch pots in equal parts sandy loam and peat. Cuttings can be taken from soft wood in early summer. Tear off small side shoots with a heel attached, then insert them into coarse sand or a mix of sand and peat and mist frequently. When rooted, misting should be reduced and the cuttings allowed to grow by potting in small pots. Young seedlings of 4 inches should be cut back to 3 inches tall and side shoots must be cut as well to create a fully branched tree.
