Deb, what is the soil like along the walkway? All day sun? You might want to try Zinnias, Salvias, Celosia, tall Marigolds. (All these would do well if the soil is not heavy clay.) You won't have to tweak the colors to work with the Crocosmia Lucifer, as these are available in an array of hot colours. All three seed easily, and require minimal maintenance. Plus, you could intersperse Sedums, Peppers (yes - Peppers!), Basil & perhaps some of the shorter variety sunflowers amongst them. That's a narrow space, but it presents a splendid curve for the eye to land on. I grow ornamental peppers & taller herbs in with flowers in the landscape. Fun, different, fairly low maintenance, plus I can dig them up & overwinter for the following year.
