1 Spiraea

Spiraea, Zones 3 to 8

For an easy-to-grow summer flowering shrub that does best in full sun with exciting color, look for a spirea at the garden center. Spireas provide several seasons of interest, but it’s the summer blooms that are truly impressive. While the individual flowers are tiny, together they pack a punch. Be sure to choose a cultivar that's right for your space—some grow only 18 in. tall, while others can grow to several feet.
