For years, I've planted double rows of daffodils, or free-form beds falling down the hill ending in a point of sorts. Last fall I dug little crescent moon shapes on the ends of some beds and planted daffodils overseeded with various spring annuals: Larkspur, Sweet William Dianthus, two kinds of Poppies, Alyssum.
This grouping has larkspur, sweet william and a few poppies and snaps in front of daylilies.
This area has 2 different kinds of poppies among the daffodils and dormant daylilies just coming up behind.
By putting daylilies on the ends, the bigger beds of perennials and shrubs need not be disturbed and I'll maybe remember that daffodils are on the ends. When the spring annuals fade, summer annuals can be seeded in. Sweet William lasts for at least two years.
