Some perennials show their best work in the autumn season. Here is a short list of cultivars that keep colors in the garden through Indian Summer and into the first frosts. Harvest colors dominate: yellows, reds, golds, and tans. Some use flowers and some use foliage, but all of them are gardenworthy.
CHRYSANTHEMUM

Among the last perennials to bloom, this Chrysanthemum is one of four garden-hardy cultivars bred locally by Erica Adam.
HELENIUM
‘Fuego’
Flowering in early Autumn, ‘Fuego’ is one of four brightly colored selections from the autumnale species.
