I am new to lilies and have started a bed with the very generous help of another lily lover. However, I was wondering what else can I add to the bed to complement the lilies. Should I just let the lilies fill in the space and enjoy the greenery or is there something that other gardeners use to create more color once the lilies have put on their show?
the bed is currently 17 feet long and about 4.5 feet deep. Full sun. Zone 7b.
