There is a garden near our place that is a stunning riot of color from early spring through late fall, with a different set of flowers predominating in each season. I usually make a detour on my way home from work every couple of days, just to track the changes. Spring, for instance, sees huge masses of tulips, daffodils, and other spring-flowering bulbs, followed by tree and herbaceous peonies and rhododendrons. From late summer through fall, tall dahlias are the stars of the show, interspersed with various other late flowering annuals and perennials.
Many gardens around town are quite manicured and there is no shortage of creative design either, but hardly any have such diverse and labor-intensive plantings all through the seasons.
