Indigofera szechuensis
Species of plant in the family Fabaceae
Indigofera szechuensis (syn. Indigofera potaninii) is a species of flowering plant in the family Fabaceae, native to Tibet and central China.[1] It is typically found growing on slopes, along trails, and on streambanks at 2,500–3,800 m (8,200–12,500 ft) above sea level.[2] It is a non-climbing shrub reaching 2.5 m (8 ft).[2]
It is the namesake of a species complex that also includes Indigofera calcicola, I. delavayi, I. franchetii, I. hancockii, I. lenticellata, I. pendula, and I. rigioclada.[3] Most of what is cultivated in the United Kingdom as Indigofera potaninii is actually Indigofera howellii.[2][4]
