Summer is a busy time for the home gardener. Deadheading flowers, trimming hedges, keeping up with bugs, and providing moisture to thirsty plants takes a lot of time and energy. At the end of a long, summer day in the garden, when you finally have time to sit back and kick up your feet, the summer flowers that surround you will make all the work feel worthwhile. You have many choices when it comes to flowers that bloom in the summer, in shades from pastel to vibrant.
Hydrangea is a classic garden flower which is also wonderful as a cut or dried flower. Although certain varieties of hydrangea can take the heat, they will require some protection from the afternoon sun. Consider the 'Seratta,' a lacecap hydrangea that is quite heat-tolerant, or any of the varieties in the Endless Summer collection. Give 'Twist-n-Shout' a try, or any big- leaf hydrangea, and you can choose whether you want blue or pink blooms just by changing the pH of your soil (pink blooms in alkaline soil, and blue blooms in acidic soil).
The alstromeria is a favorite in florist's bouquets. Planted in the spring, they will be your first to flower in the summer garden, generally blooming in early summer. You have many colors to choose from. If you live where summers are particularly hot, plant alstromeria in an area where they will get shade in the afternoon. This plant is hardy to U.S. Department of Agriculture (USDA) Plant Hardiness Zones 7 to 11.
Even just one canna lily can lend your garden a tropical feel; planted en masse they are a striking focal point. This is truly a long-lasting summer flower and will bloom all season, in tropical colors. Depending upon the cultivar, a canna lily will grow from 16 inches to 60 inches in height.
