There is perhaps no more underrated summer activity than gardening. Gardening is exercise that doesn't require hours spent in the gym. Instead, it's an opportunity to spend time in the fresh air and sun. It's meditative, calming, and as challenging as you want it to be. Plus, it's incredibly rewarding, no matter what you're trying to grow. Planning and maintaining a garden that's full of the best summer flowers is as wonderful a hobby as any. And though you may be familiar with spring or fall flowers, it can be harder to know which are just right for those hot, hot summer months.

Even if you don't have the fanciest gardening tools and accessories, choosing the best flowers to plant that will bloom in summer is actually quite fun. It's as simple as finding some options that work for your garden's particular climate and setting and getting to work. (This USDA Plant Hardiness Zone Map can help.) Just make sure you have a refreshing summer drink to look forward to after a hard day of gardening and you'll be all set. If you need ideas about what flowers to begin with when planning your summer garden, here are 30 of the most gorgeous, versatile, and show-stopping summer flower varieties to choose from.
