15 Annuals That Bloom With Pretty White Flowers

When you're attempting to brighten up a yard or accentuate a walkway, there are countless plant and sunflower varieties that will do the job. While colorful blooms like vibrant yellow daisies or whimsical purple pansies are great options, there is definitely something to be said about white annuals. Not only are white flowers inviting with their clean, bright, and upscale feel but they can also be of great benefit when you're looking for a stunning floral display. 

According to Tilly, annuals bloom faster and longer than their perennial counterparts. They are also more affordable, as they typically only bloom for one season instead of multiple years. Plus, these types of flowers are incredibly easy to grow from seeds and even self-seed, which means you don't necessarily need to plant an entire new flowerbed the following year. 

White annuals make for a classy-looking garden that you'll love to spend time around and, of course, will impress visitors, too. Ultimately, they are a great choice for those who want a beautiful blooming garden quickly or for those who enjoy switching the look of their flowerbeds year after year.
