20 best perennial plants
Perennials are the largest group of garden plants and offer magnificent diversity for every location from sun to shade. Plants range in size from ground-covering and clump-forming varieties just a few centimetres high, right up to statuesque giants a couple of metres tall. Growth is quick and most plants reach a mature size within one or two growing seasons. Perennials mostly flower in spring, summer, or autumn, with a handful blooming in winter, and many have attractive foliage too.
