Semi-hardy annuals can be planted in the fall when temperatures begin to moderate in September or early October. These plants include chrysanthemums, snapdragons, ornamental cabbage, and kale.
Hardy annuals can be planted early winter from mid-October to November. Hardy annuals take considerable frost and freezing, and include pansies, Johnny-jump-ups, China Pinks, ornamental cabbage/kale, and hardy cultivars of snapdragons (Liberty or Sonnet series).
