'Chaste Tree'. This very long cultivated medium to large sized deciduous shrub is strangely not often encountered. It has elegant aromatic foliage and produces erect racemes of fragrant violet-blue flowers en-masse at the end of the shoots in Sept and Oct when most other things are long over. This is a good hardy form with broader leaflets. Sun, well drained soil. Heat and drought tolerant. Used for hundreds, if not thousands of years as a hormone regulator for both men and women.
