If you are looking for an economical way to have flowers in your yard year after year, grow flowering perennial plants. The life cycle of perennial plants can last for several years with propagation by seed or division of the plant. Perennials can be chosen according to sun exposure and soil conditions, so determine the placement of your plants before making your selection. A few popular flowering perennial choices are bleeding heart, Russian sage, shasta daisy and black-eyed Susan.
The bleeding heart (Dicentra spectabilis) has a bushy growth and reaches a mature height of 24 inches. It grows well in USDA hardiness zones 2 to 9 and requires moist, well-drained soil and partial shade for optimal growth. The heart-shaped flowers are pink and white and bloom in late spring through early summer. Texas A & M AgriLife Extension reports that the bleeding heart goes dormant by the middle of summer. It is advised that you coordinate bloom times for surrounding plants to fill in any void. This plant can be used in flowerbeds, as a potted plant and in borders. It is propagated by seed in late summer or by division in the fall. Cultivars of the bleeding heart include Alba and Goldhart.
Russian sage (Perovskia atriplicifolia) grows well in USDA hardiness zones 3 to 9. It has silver foliage and grows upright to a height of up to 60 inches. Russian sage blooms late in the season with blue-spiked flowers. This plant prefers very well-drained soil and full sun. It is drought tolerant and easy to maintain with very little division necessary. Propagation is done by cuttings in the summer or by seed.
Cultivars of Russian sage include Longin, Blue Spire, Little Sprite and Blue Mist.
The Shasta daisy (Leucanthemum x superbum) grows well in USDA hardiness zones 4 to 9. It prefers well-drained soil and full sunlight and will reach a height of up to 36 inches. The Shasta daisy blooms from June through September and produces white flowers with a yellow center. This perennial can be used for borders and as cut flowers. The Shasta daisy should be cut down in September to spur new growth and extend the life of the plant, according to the University of Illinois Extension. Propagation is by division in the fall.
Cultivars of the Shasta daisy are Becky, Aglaia, Snowcap, May Queen, Old Court, Sonnenschein, Crazy Daisy and Alaska.
The black-eyed Susan (Rudbeckia fulgida), also known as coneflower, reaches a mature height of 30 inches and is appropriate for USDA hardiness zones 3 to 9. This perennial flower prefers well-drained soil with full sun to partial shade. The flowers of the black-eyed Susan are golden-yellow with a black center and are in bloom from July through October. The black-eyed Susan will flower again, if cut back after the first flowering, reports North Carolina State University Extension. This plant can be propagated by seed or by division in the spring or fall months.
Cultivars of the black-eyed Susan include Goldstrum and Viette's Little Suzy.
