You need to combine annuals and perennials. This should be a given for anyone who likes flowers.
You say that you want lots of bloom but you only want plants that come up every year? You say that you only want those things that flower from May through October? Get over it.
Perennials are a must for landscapes not only because they return to delight us season after season. Because some of these plants grace our gardens with flowers early in the season and others later in the summer, perennial plants offer an ever-changing dance of color. Many have foliage that is textured, variegated or multi-hued as well. You definitely want perennials.
Annuals are also a garden necessity for flower lovers. Yes, you have to plant them every spring, but most reward you with summer-long bloom. They provide the bridge color in between perennial flowering and knit all the garden players together. Not only that, but you can choose different annuals every year and completely alter the complexion of your flowerbeds.
If your garden contains annuals, perennials, shrubs and trees, you will be delighted by a kaleidoscope of color from spring through fall.
Gardens teach us flexibility. The plants are saying, “You only want plants that come back every year? Snap out of it!”
