In this picture you can see the daffodils I have in my front garden. To hide the daffodil foliage, or disguise them rather, I have a couple other perennials that will come to the forefront. In May the bed becomes filled with the purple flowers of salvia and the yellow blooms of daylilies. My tulips, which are in the sidewalk garden, don't have much to disguise their foliage but I leave the leaves to die back on their own anyway. I've been able to maintain a reliable display of tulips this way. Last year I planted lantana among them but it won't return here - at least not without help from the gardener.
What perennials do you think make a good sequential planting for bulb flowers to help hide the foliage?
