You may be wrapped up in thoughts of winter at the moment, but summer is on its way and now is the time to start thinking about the summer growing season. To help plan the garden of your dreams, here’s a round-up of some popular summer flowers. Most are fairly easy to care for and produce stunning blooms for your enjoyment throughout the summer season.

1. Zinnia

You’ll find zinnias in nearly any color you’re looking for—pink, orange, yellow, red, white, purple, and more, meaning there’s probably a beautiful option to fit the vision of nearly any gardener. As an annual, they will only last one season, but they put on quite the display while they’re around. Zinnias grow well and look great in a number of settings whether it’s in a garden, container, or window box. Because of their beautiful shape and vibrant colors, zinnias are also very popular as cut flowers.

Dahlia Dahlia

2. Dahlia

Blooming in a wide variety of saturated colors, dahlias bring a cheerful touch to gardens throughout the United States during the summer months. Their roots are tubers rather than bulbs, and larger tubers typically lead to a larger plant and more flowers. Overall, these summer flowers are fairly easy to grow, but you’ll want to wait to plant your dahlias until after the last frost has passed in the spring.

Most varieties grow best in full sunlight and are loved by butterflies, ladybugs, and bees. Though some varieties of Gloriosa Daisy are perennials, you’ll also come across annuals and biennials.

Possibly one of the most popular summer flowers out there, sunflowers—with their tall stems and bright yellow petals—seem to be capable of bringing a smile to the face of anyone who passes one. Sunflower heads move throughout the day, following the path of the sun, so keep this in mind as you plant. There are few things more beautiful than a large field of sunflowers in bloom, but these flowers are also stunning when grown in smaller quantities. Most sunflowers are annuals, so you will need to plant them each year.
