Summer is the season of perpetual blooms and harvests. We hope you will find plenty of flowers on this list for your gardens. Whether you are looking for a seasonal pop of color or something to transition your garden from a vibrant summer to moody autumn, you can find it all here. Fill your home with the scents of nature with popular summer blooms such as lavender, carnations, delphinium, dahlias, or sunflowers! Don’t forget to add some unique types, like Bells of Ireland, for a fresh flare of light green to offset any vibrant mix of colors.

While fruits and vegetables are important, they perform best when grown amid a variety of flowers. Attract beneficial pollinators and insects by planting flowers throughout your garden. We would love to see what you choose! Please share your selections online by tagging @TrueLeafMarket on Facebook and Instagram.

Below you will find flowers that can be grown across the United States. Contact your local extension office or universities for information on what flowers do best in your area. We have compiled a list of Universities known to provide quality growing information for your local climate and weather conditions. Other helpful advice may be found from universities in states with similar conditions. Find links to these resources on our USDA Hardiness Zones By State infomation page.

While all of these flowers are known to bloom throughout the summer season, each comes with its preferred growing conditions. We recommend learning more about where these flowers grow best on their product pages or the recommended resources above. Looking for flowers that bloom all season long?
