Indigo heterantha is quite popular in England and has even gained the RHS award of merit yet it is rarely seen in American gardens or nurseries.

I have grown indigofera heterantha for four years at the sunny southeast corner of our brick house in a dry location with unimproved soil here in our Cincinnati temperate climate. It has grown from a one gallon can to a six foot tall by four foot wide shrub that blooms from August thru mid October with beautiful sprays of tiny lavender pink blossoms. In early winter, after bloom is over, we cut it down to ground level, and since it has a well developed root system, the shrub regrows to its former size by mid summer.
