When there is already an abundance of green tones in the natural landscape you might ask yourself, “why would I want to add even more green?” To answer that, here are some reasons you might want to add green flowers to your garden scheme followed by a list of green flower suggestions to get you started!

Why to Grow Green Flowers

  • Many of the plants with green flowers produce blooms that can be described as “neon” or “chartreuse” in color. These vibrant shades stand out among different flower colors and they’re quite visible against a backdrop of deeper shades of green in the landscape or plants with purple or burgundy foliage.
  • Green is a calming color that lends a refreshing, cooling feeling to a space in the heat of summer when a mass of bright color may feel overwhelming.
  • Green flowers are a fun change of pace from the typical flower colors you might use year after year. They’re one of the least common flower colors and add uniqueness and novelty to a garden. Incorporating just one or two plants are sure to make great conversation starters!
  • Green flowers often attract some of the lesser discussed pollinators such as beetles, moths, and flies. They may not be as flashy as butterflies, but they can be beautiful and interesting in their own unique ways, and they make essential contributions to flower pollination throughout the plant world.

16 Plants with Green Flowers for Your Garden

If you’re still not convinced that plants with green flowers have a place in your garden design, have a look at the following list of plants. Not only do these produce green flowers, but many offer unusual flower forms that will appeal to anyone who wants to create a show-stopping flower garden with unique features.

1. Euphorbia (Euphorbia characias subsp. Wulfenii)

The genus Euphorbia encompasses some of the most varied species of the plant world; from poinsettias to cacti-like succulents, to the array of ornamental species that have become popular for home landscapes. All are easy to grow and offer unique flowers and foliage features.

2. Green Chrysanthemum (Chrysanthemum species)

Green chrysanthemums are a naturally occurring color and they are available in spider and pompon types.
