Common outdoor flowers usually include perennials due to their great diversity in shape, size and color. Since perennials bloom for more than one season in a row (compared to annuals which bloom for a single season), their long life makes their stay in your a garden a lower maintenance experience without the need for immediate replanting. Whether your site is wet, shady or dry, there is a perennial that suits your outdoor garden's needs.
Blanket flowers (Galardia x grandiflora) are common outdoor perennial flowers that display round multi-colored blooms in orange, red and yellow hues from June through October with green foliage. Thriving in full sunlight and well-drained soil, tolerances include dry soil, heat and drought. To promote reblooming of blanket flowers, deadhead to allow new growth. Blanket flowers grow to a height of 18 to 24 inches and should be planted in USDA Hardiness Zones 2 to 10, according to the University of Illinois Extension.
Fringed Leaf Bleeding Heart
Fringed leaf bleeding heart plants (Dicentra formosa) are common outdoor perennial flowers displaying flowers in pink, white and red from May through August with green foliage; blossoms resemble the shape of a heart with what looks like an emerging red drop. Thriving in partial sun to full shade, the fringed leaf bleeding heart prefers moist, well-drained soil; plant nearer to the soil's surface as excessively deep planting will cause rotting. Additionally, be sure soil remains consistently moist throughout the summer season to encourage repeat blooming. This common outdoor perennial grow to a height of 15 to 18 inches. Plant fringed leaf bleeding hearts in USDA Hardiness Zones 3 to 9, as suggested by the University of Illinois Extension.
Spiderwort (Tradescantia x andersoniana) is a common outdoor perennial flower that displays blue, purple, white or pink flowers from June through September with yellow to green long, grass-like foliage. Thriving in full sun to partial shade, spiderwort prefers moist, well-drained soil but tolerates wet sites; keep spiderwort out of extreme shade to prevent weakened plant structure. This perennial flower grows to a height of 18 to 24 inches and should be planted in USDA Hardiness Zones 3 to 9, according to the University of Illinois Extension.
Oriental poppies (Papaver orientale) are common outdoor perennial flowers displaying vivid orange, red, pink or white blooms with darker, contrasting centers and blue-green foliage. Bloom time is May through June. Thriving in full sunlight, Oriental poppies prefer moist, well-drained soil. For newly planted poppies, apply a thin coat of mulch during the first winter season. Oriental poppies grow to a height of 2 to 3 feet; plant this perennial flower in USDA Hardiness Zones 2 to 7, as recommended by the University of Illinois Extension.
