How to Use Annuals for Instant Color
Annuals are great for gardeners who want instant color and big impact. You can plant colorful annuals in the ground, in containers of all sizes, or fill small spaces that just need a touch of "something." Annuals are versatile in your garden design, as well: You can fill large areas with blocks of color and texture, or change color themes each year.
For the brief time annuals are growing and pumping out flowers, you get a lot of bang for your buck. They're hard to kill. Indeed, some of them keep blooming their cheery heads off even when you neglect them. And if you live in a frost-free climate, your "annuals" become perennials.
The main drawback of annuals is economic. You have to buy new ones every spring.
You can use annuals
To fill an entire flowerbed (this popular use is why some places call annuals bedding plants)
In container displays — in pots, window boxes, patio planter boxes, and more
To fill a hanging basket
To edge a walkway
To "spot" color in a perennial bed
In edging and as decoration for a vegetable or herb garden
To cover over or at least distract from a fading spring bulb display
If you shop earlier in spring (before the garden center has been picked clean) or go to a place with a big selection, you see lots of choices. If you find certain types too boring or common, look around for alternatives — one big trend these days is familiar annuals in new colors, even bicolors. Get creative! Have some fun!
