Great plant for fixing nitrogen in the garden and for honeybees
Windbreaks - The caragana is recommended for planting in the outer rows of multi-row plantings. It can be used to neutralize soil to prepare for further planting. A legume, the caragana fixes nitrogen. It is suitable for planting in single-row field windbreaks where a dense, short barrier is desired.
Wildlife habitat - The caragana is used for nesting by several songbirds. The seeds are occasionally eaten by a few songbirds. The plant is not a preferred food for browsing animals, but its fragrant flowers attract many pollen-consuming animals.
Erosion control - The caragans has an extensive root system that can be used to assist with erosion control.
Ornamental - The caragana, with its small fragrant flowers and attractive compound leaflets, is used alongside lilacs to create a 'compare and contrast' appearance.
Bee plants - The caragana has a fragrant flower that naturally will attract bees. The honey created has a pleasant taste, slightly 'fruity'.
Cultivated food source - The caragana has a slightly bitter tasting 'pea', usually 3-4 to a pod, that is edible. They should be cooked before eaten. There have been no verified cases of poisoning from consuming the caragana pea. Additionally, the yellow flowers which have a taste like peas, can be used in salads to add colour and some flavour.
