I love the foliage on 'Purple Knockout', although the flowers are nothing to write home about... I just wish it would last (and increase in size) from year to year... I've grown several different salvias on one corner of my perennial area, and I do like them! If you like the look of salvias, you might also like the flowers on penstemmon... I've got P. smallii up by the driveway, and it has wonderful salvia-like blooms in spring.
