Extend the flowering season of your garden from summer to fall with this harmonious and serene-looking combination of late bloomers. Only 3 ingredients are required to achieve this lovely look: Sedum 'Herbstfreude' (or 'Autumn Joy'), which is probably one of the best of all sedums; the vigorous and elegant Sage 'Phyllis Fancy' and one of the easiest annuals to grow, Sweet Alyssum (Lobularia maritima).
