Here is a lovely way to introduce waves of colors in your fall garden. Pair Aromatic Aster (Symphyotrichum oblongifolium), whose profuse purple-blue flowers will enliven your borders long after the other flowers are gone, with Mountain Fleece (Persicaria amplexicaulis) which enjoys long-lasting crimson flower spikes. This soft and simple contrasting combination is fairly easy to re-create and requires little maintenance. So enjoy!
