While perennials are celebrated for their low-maintenance qualities and ability to come back year after year, annuals are beloved for their rich and bright blooms that can last for weeks and weeks. If you crave beautiful flower blooms in your garden all Summer long, then you need to plant some annuals in your yard, asap!
Whether you’re looking for bright colors, height, or interesting flower petals, there’s an annual out there for you just waiting to be planted.
But first, let’s talk about what differentiates annuals from perennials. Simply put, annuals grow for only one season and must be replanted year after year if you want to enjoy them in your garden next Spring. This means you’ll have to purchase new plants or seeds every year. Perennials on the other hand, can grow in the same spot for several years without replanting.
Annuals can be a little more work than perennials for this reason but they definitely reward you with longer blooming times. Plus, some of the most striking and popular flowers are annuals. When you plant any of the flowers below, you’ll enjoy beautiful blooms through the Fall and reap the benefits of your hard gardening work until early frost!
Another benefit of planting an annual is that it gives you the opportunity to figure out whether or not you like that particular flower in your garden. If you do, you know you’ll repurchase it next year, and if you don’t, you’ll know that you need to replace it with another flower.
Now let’s delve into 16 of the most stunning annuals that would make any garden-lover swoon!
Annuals That Bloom All Summer Long
This waxy flower is a stunner and one of the most popular annuals around. The deep green foliage gives way to small, wax-like petals that grow under beautiful foliage. They bloom from June to frost and come in shades of white, pink, red, and multi-color combinations. They’re also low-maintenance and easy to grow! Begonias thrive in moist and fertile soil and can tolerate extreme temperatures. If you plan to use these as ground covers, try growing them indoors from seed a few weeks before Spring.

Poppy flowers are some of the most well-known annuals and for good reason. There are many different varieties, and some are actually grown as perennials. They can grow anywhere from 1 to 8 feet tall and will grow throughout the Summer!
