Calibrachoa Hybrids

• Sunset, a magazine focused on the Western lifestyle, created a list of the five best best summer flowers and put Calibrachoa hybrids at the top. Sunset focused on flowers that perform reliably during the summer so that you can plan your summer blooms. Calibrachoa hybrids are like petunias, but hardier, producing small flowers that last a long time, including the entire summer. If you want the calibrachoa to grow vibrantly, use plenty of water and fertilizer. If you have unusually hot summers, try planting the Tequila Sunrise, a flower with bright orange and streaks of yellow.
  
  

Daylilies

• Life script, a website devoted to healthy lifestyles, compiled a list of the top flowers that bloom throughout the season, based on their hardiness. Daylilies, especially the Stella De Oro, can bloom for a very long period, from late May to the first frost, making them one of the best summer flowers. The Happy Reruns and Pardon Me's will not flower as long. These daylilies can also take a beating during the summer without losing their flowers.
  
  

New Guinea Impatiens Hybrids

• Sunset recommends New Guinea impatiens hybrids for the summer; in fact, they need very strong sun to bloom fully, so plant them in the sunniest part of the garden. They also need plenty of water to thrive.
  
  

Black-eyed Susans

• According to Life Script, black-eyed Susans are among the best summer flowers because of their love for sunny weather. This daisy produces golden yellow flowers with distinct, dark brown heads. Black-eyed Susans attract butterflies.
  
  

Coreopsis

• Life Script describes the coreopsis as one of the best summer flowers for beginners because the daisy is very hardy. This daisy grows aggressively and is native to North America, so the flower has already adapted to the weather conditions. The plant produces flowers that are either creamy yellow or golden yellow.
  
  

Salvia Splendens

• Sunset put Salvia Splendens third on its list of the summer's best flowers. In fact, this flower will not thrive well during mild summers. Give them moderate water so that they can grow strong root systems. This flower produces spikes with a red salmon color, and the Van Houttei variety produces maroon flowers mixed with scarlet-orange.
