15 Stunning Green Flowers You Should Grow In Your Garden

When you imagine a beautiful flower garden, which colors come to mind? For many, it might be red roses, white daisies, yellow daffodils, or purple lilacs that are at the top of their list. One flower color that is looked over, again and again, is green. There is already plenty of green naturally occurring in the garden; Surly grass, plant stems, and leaves bring forth all the greens you need. Or do they? 

Green flowers such as gerberas, bells of Ireland, and Mediterranean spurge can add stunning visuals and attractive textures to your garden. They are also thought to bring luck, optimism, good fortune, and youth to gardeners, according to Country Living. Though green flowers are often said to be difficult to care for, many annuals and perennials are surprisingly low-maintenance. Before planting any of these flowers, keep in mind your city's climate and your flower's growing conditions. Not much is worse than buying lots of beautiful green flowers only to see them die after a few weeks due to the wrong environment.

This green hydrangea (hydrangea paniculata), referred to as limelight, is coveted by many gardeners. Not always the first choice for beginners, the paniculata species is, in fact, very easy to grow, according to Proven Winners. Throughout its bloom season, the flowers can turn from green to shades of pink and white. 

If you are looking for a fun, color-changing flower to bring new life to your garden, this 6- by 6-foot shrub may do the trick. Hydrangeas grow in USDA hardiness zones 3 through 9. Remember, before you plant, that they enjoy partial sunlight and well-draining soil.

Green cockscomb (celosia cristata), also known as spring green is a flower that enjoys hot, full sun conditions, says The Gardener's Workshop. At maturity, the cockscomb plant is 12 inches tall and wide. It produces unique, velvety flowers with twisting petals that accent its dark green foliage.

Other than green, you can also find gorgeous cockscomb flowers in white, red, yellow, pink, and orange. It grows best in moist, loamy soil in USDA hardiness zones 9 through 12.

Calla lilies (zantedeschia aethiopica) of the green goddess variety are a rare sight. Their siblings, which feature white trumpet-shaped flowers, are more often used in bouquets, but the green versions are less well-known. Calla Lilies can grow up to 36 inches tall and bloom from late spring to midsummer, reports Gardenia. 

These flowers do best in USDA hardiness zones 8 through 10 and should be planted in moisture-retentive soil in partial sun. Many gardeners like to use their Calla lilies as border plants or as edging around ponds.

Oaks lily, mean green, Forsyth flaming snow, and Tutankhamun are just some of the hemerocallis species' varieties that feature beautiful lime green color on their petals, as described by HGTV. The blooms on daylilies can vary from species to species, but most will measure about 4 to 9 inches across. 

All daylilies are low-maintenance plants that grow in USDA hardiness zones 3 through 10. They can survive drought, poor soil, and shade. Though, you should plant them in fertile, well-draining soil and water them about once per week, says Almanac.

Green envy zinnias (zinnia elegans) are highlighted by their flowers' bushy form and chartreuse color. When planted sometime between April and June, you can expect the vivid flowers to bloom during the midsummer to fall season, according to Renee's Garden. 

You can grow Zinnias almost anywhere as annuals, but they prefer living where temperatures consistently stay about 50 degrees Fahrenheit, such as in growing zones 9 through 11. When you are ready to plant your zinnias, be sure to pick a location with ordinary garden soil and full sun.

Green hellebore (helleborus viridis) is a perennial herbaceous flower that can grow up to 16 inches tall, notes Nature & Garden. The green-petalled plant blooms from February to June. In nature, hellebore plants grow in forested areas with rocky soil where they receive partial sun and plenty of water. 

They need the slightly colder climates of USDA hardiness zones 3 through 9 to survive. Other green hellebore species include helleborus argutifolius, helleborus sternii, helleborus foetidus, and helleborus odorus. Although slightly different from one another, they all share the same growing conditions.

Although boxwood shrubs (Buxus spp.) aren't flowers, they can be a great green addition to your garden, and are commonly used in landscaping, explains Proven Winners. They stay beautiful year-round with proper care, and they can tolerate most types of soil and climates. 

Their preferred hardiness zone is most often listed as 5 through 9, but some cultivars can withstand colder temperatures. Keep in mind, that boxwood shrubs can become quite large, sometimes reaching up to 20 feet tall and 8 feet wide. Provide your shrub with a wind-sheltered location that receives partial sun.

Chrysanthemums or mums are one of the most common green flowers that you can find. More than 100 cultivars of the flower are known today. Some green Chrysanthemum varieties include key lime, green mist, star mist, and green star, as described by Balcony Garden Web.

The flower, which is made up almost exclusively of layers of sepals, cannot reproduce according to Mountain Valley Growers, and can only be propagated by graftings and cuttings. 

The green rose can survive in growing zones 5 through 11 as a perennial. They need full sun, well-draining soil, and fertilization in the spring. Their 4-inch-wide leafy blooms stay open during the spring and summer atop stems that can reach 4 feet tall.

Mediterranean spurge is characterized by an upright growth habit, petal-less green cyathia flowers, and narrow leaves. The plant can grow in soil that is rocky, dry, and shallow.
