Flowers for Different Seasons

Annual and perennial flowers provide the garden and landscape with seasonal variety and bright and bold accents. When planted in every season, the landscape remains in color year-round and creates an attractive landscape design. Grown in a wide range of shapes, sizes and colors, flowers are a garden staple and help to provide a non-stop display of blooms from winter to fall.

Winter

Hellebore (Helleborus --- hybridus cvs.) blooms in midwinter when most of the landscape is colorless. It grows 1 to 3 feet tall and wide and has a clumping growth rate. The nodding-like, frost-tolerant flowers of hellebore grow in a wide range of colors, including, green, white, pink, purple and yellow. The leather-like, deep green leaves of the hellebore are evergreen, meaning they retain their color year-round, an added benefit to the garden. Hellebore is a versatile winter plant and is both tolerant of heat and humidity. They grow best in full to part shade and well-drained, nutrient-rich soil that is neutral to alkaline. Plant hellebore in USDA zones 4 to 9.

Spring

Tulip 'Calypso' (Tulipa greigii 'Calypso') is a spring-blooming perennial flower that has a moderate growth rate. It grows in small clumps and reaches 6 to 12 inches in height. The large orange and red flowerheads of tulip 'Calypso' are edged in primrose and have a black base, an unusual color pattern to a tulip. The dramatic, stippled foliage is variegated with pale green and deep purple for a lush and striking display to the garden. Tulip 'Calypso' emerges in early spring to last through the season. Versatile, it is frost-tolerant to withstand an unexpected drop in temperature within the garden. Tulip 'Calypso' grows best in full sun to part shade and well-drained, fertile soil. They are suitable grown in USDA zones 3 to 8.

Summer

Blanket flower (Gaillardia pulchella) is a summer-blooming, annual flower that has a moderate growth rate and clumping habit. It grows 18 to 24 inches tall and 10 to 12 inches wide. The red to orange daisy-like flowers are edged with yellow and have a deep crimson to purple center that attracts butterflies and birds. Providing bright bursts of color all summer long, blanket flowers also make an ideal fresh cut flower. They have a high drought tolerance and grow best in full sun and well-drained, fertile soil. Blanket flowers grow in all USDA zones.

Fall

October skies aster (Aster oblongifolius 'October Skies') is a perennial flower that blooms in fall. They grow 1 to 3 feet tall and have a spreading growth habit. The masses of daisy-like blooms on October skies aster are dark sky blue, hence the name, and attract butterflies to the plant. They are both deer- and frost-tolerant, creating a hardy fall flower. October skies aster grows best in full sun to part shade and well-drained soil. They are suitable for growing in USDA zones 4 to 8.
