INDIAN CURRANT or coralberry makes an excellent permaculture plant..........as this decorative little bush( 1 meter high) has an extensive fibrous root system that sends out suckers for bank stabilization and erosion control on steep slopes....probably the best bush for those shady embankments. Edible red fruit grows in abundant clusters all over the branches....the fruit also known as “Indian current” hangs all winter long and thus can serve to feed winter wildlife and "hungry hikers". Very hardy(Zone 2) and adaptable to many soil conditions and climate extremes. Should be included in Forest gardens and permaculture plantings more often as indestructible native food plant. Want to stabilize your slope ...try this plant.
