Perennials are like faithful friends: trustworthy, reliable and there when you need them. You can count on them to come early, stay late, and be there in between, when nothing else is in bloom. Low maintenance gardening often involves perennials because, unlike annuals, once they are planted these plants don't require the time and expense of yearly replaning and should last for several years in your landscape.
The key to growing perennials successfully is to insure that they are given a well-drained location which can be hard in our clay soils. Therefore, soil amendment is necessary when planting. Some of the longest blooming perennials that do well in our area include Blue Salvia, Coreopsis, Rudbeckia, Stella D'Oro Daylilly, Purple Cone Flower and Shasta Daisies.
