Perennial plants are the foundation of a garden, returning year after year to enliven a yard with familiar blooms. Gardening with perennials is an easy way to reduce the amount of time it takes to maintain a garden, allowing the gardener to spend less time planting and more time admiring the plants.
The day lily (Hemerocallis) is a genus of perennial flowers that contains thousands of cultivars. These showy plants are grown worldwide and cherished for their spectacular blooms, which come in a range of bright colors. The flowers of the day lily only bloom for a day, but luckily each plant produces an abundance of blooms during a season. Day lilies require well-drained soils, and they will tolerate dry soils. A place in the garden that's almost full sun with a little shade is ideal. Different varieties of day lilies require different gardening zones, so check with your local nursery before purchasing a cultivar.
Foxgloves (Digitalis) are distinctive-looking perennials that produce rows of tubular flowers in midsummer. Flower colors range from white, purple, pink to red, and many are flecked with darker colors on the inside of the flowers. Foxgloves do best in full sun or light shade with moist, well-drained soil. Some species of Foxgloves are biennial, meaning they die after two years--be sure to check the species before you buy. Most species of foxglove will grow in gardening zones 4 through 8. Gardeners who have problems with deer devouring their flowers may want to try foxgloves, as deer will generally avoid eating the plant.
The Shasta daisy (Leucanthemum superbum) is a low-maintenance perennial that offers gardeners the classic daisy look, with blossoms that have a disc of white petals around a bright yellow center. Most species of Shasta daisies are fairly hardy, growing in gardening zones 4 to 9. The Shasta daisy requires well-drained soil, and most soil types that aren't too heavy in clay will work just fine. The plant blooms in midsummer, and deadheading the flowers will result in a longer bloom period.
