Acacia senegal. This small tree is used to make chewing gum and candy. Also used in lozenges for sore throat and for diarrhea and dysentery. The small tree has pale yellow fragrant flowers. The tree can be grown indoors in containers.
Acacia senegal or Senegalia senegal, is a small thorny, deciduous tree with yellowish white bark and feathery crown, reaching a height of 4-6m and a girth of 30-60cm. The tree is native to Sudan, and grows throughout India, particularly in Haryana, Gujrat, and in the dry rocky hills of Rajasthan (the Aravallies). Leaves are bipinnate, with stipular spines and flowers are yellowish and fragrant 5-10cm long spikes. Pods are about 7.5cm long, straight, strap-shaped, and contain 5-6 seeds. Acacia senegal seeds require soaking in Conc. Sulfuric Acid for about 20-30 minutes for successful germination. The seedlings require protection from grazing, wildfire and weeds for about 2 yrs. Acacia senegal is a primary, source of Gum Arabic, which is a main ingredient of soft drink syrups, while the wood is a good source of fuel.

Growing Info, follow in order:
Scarification: Pour boiling water over seed , let cool in water for 24 hours.
Treatment: Acid (H2SO4) Scarification, Hot Water
More tips:
(1)Planting Instructions: Soak seeds overnight in warm water. Sow seeds in light-weight sterilized soil. Water daily.
Soil Facts: Requires a well prepared light soil. Use general purpose fertilizer when preparing soil.
Germination: 12-18 days
(2)Acacia senegal seeds will usually germinate in 21 days. Sow Acacia senegal seeds about 2mm deep in a Well drained seed sowing mix at about 25°C. Soak Acacia senegal seeds in warm water, which should be changed daily.
(3)Presowing treatments including scarification, osmotic priming and hardening were applied to seeds of Acacia senegal (L.) Willd. from Goz Ashgar, Sudan. Seeds exhibited a typical triphasic pattern of water uptake leading to germination. Germination occurred continuously over a maximum of 18 days depending on presowing treatments and temperature. HCl and manual scarification improved germination rate. H2SO4 scarification reduced both germination rate and capacity. Osmotic priming increased the germination rate of treated seeds. Hardening with distilled water had no significant effect on germination rate or capacity. Capacity was high between 20 and 40 deg C, but fungal attack increased with increasing temperature. Emergence time for seedlings in glass house trails was decreased by presowing treatments. Height growth rates were reduced by all treatments. Presowing treatments did not affect root or shoot biomass.
