Everyone wants a gorgeous garden, but no one wants to feel like they’re spending all their summer days constantly doing lawn upkeep. Just like our delicate blooms, we often crave relief from the sweltering heat, and the last thing we want to do is spend hours soaking plant beds under the beating summer sun.

On the hottest days of the year, flowers that can withstand the heat are a lifesaver, saving time, a little bit of money, and a whole lot of our mental energy, and they're not as rare as you might think. Many annuals and perennials alike can withstand hot temperatures and constant sun exposure. In fact, some adore hot weather.

Just know that their resilience isn’t an excuse to neglect your sprouts. New plants especially need time to acclimate and establish their roots with regular watering before you can leave them to their own devices. Plus, inconsistent watering can lead to wilting, stress, and a serious dampening of flower power.

So, when the temps start rising, it's important to make your rounds and check in on your pots, baskets, and beds. If you notice dry soil beneath the surface or gaps between soil and pot walls, your plant is parched. Pro tip: We recommend watering your plants in the early morning so they go into the day prepared to handle the heat. Read ahead for our favorite plants that can survive a summer heat wave.
