21 Green Flowers You Can Grow Yourself

There’s certainly no shortage of the color green in most gardens. Yet there’s a notable lack of green flowers in the vast majority of landscapes.

Is it that green flowers are practically nonexistent? Or do we just gravitate toward more thrilling hues like pink, orange, and purple when designing our gardens? I’m willing to bet it’s mostly the latter.

In this article, I’ll explore nearly two dozen plants with green flowers and how to grow them. You’re sure to discover at least one verdant-hued bloom worth adding to your garden!

Do Green Flowers Exist in Nature?

The floral industry has a number of tricks up its sleeves for making visually appealing bouquets. One such trick is the art of flower dyeing. Dyeing allows florists to sell blooms of all different colours, including some hues that might not occur in nature. 

While naturally green flowers do exist, they’re somewhat rare in landscape plants. Artificially dyed flowers are far more common because they’re both affordable and easier to source than the real thing.

Whether or not a green flower is dyed doesn’t really matter when shopping for bouquets. But it’s a huge deal when trying to find plants to grow in your own garden. 

Natural vs. Selectively Bred Flowers

The green flowers on this list can be broadly grouped into two categories. There are those that produce green flowers all on their own, and there are those that we’ve bred to produce green flowers even though their ‘normal’ blooms are a completely different colour.

If you have your heart set on growing a particular type of green flower, it should make no difference whether that colour comes naturally or is the result of breeding. You just need to be wary of purchasing the wrong varieties of certain plants, as not all of them produce the flowers you want.

Another thing to keep in mind is that plants bred to have green flowers are often much harder to source. These varieties can be incredibly rare and, in some cases, more expensive than non-green varieties. Getting your hands on, say, a Green Glow azalea is much harder than sourcing something like a lady’s mantle.

21 Green Flowers for the Home Landscape

Understanding a bit of the science behind flower colouring can deepen your appreciation for the allure of these flowers and provide a new perspective as you plan your garden.

In most plants, chlorophyll is concentrated in the leaves and other vegetative tissues. In green flowers, this pigment extends to the petals too. 

Now that we know why green flowers are so special, let’s explore some of my favourite plants with green flowers and their care requirements.

1. Green Hellebore

Green Hellebore

Helleborus viridis

  • Type: Herbaceous perennial
  • Hardiness Zones: 4 to 9
  • Position: Part sun to shade

Hellebores are clump-forming perennials that flower very early in the spring. Not only are they incredibly shade-tolerant during the bulk of the year, but they also make fantastic companion plants for a range of other flowering plants, shrubs and vegetables.

For the best results, plant your hellebores beneath a deciduous tree canopy so they get a bit of sun early in the season.

There are several types of hellebore out there, including the Lenten rose (H. orientalis) and the Christmas rose (H. niger). Only H. viridis produces predominantly green flowers.

2. Bells of Ireland

Bells of Ireland

Moluccella laevis

  • Type: Annual
  • Hardiness Zones: 2 to 11
  • Position: Full to part sun

While most of the flowers on this lid were carefully bred to achieve their colour, Bells of Ireland has been producing green blooms since the 1500s. It’s commonly used in floral bouquets, especially in the spring.

Bells of Ireland seeds are generally easy to come by and will mature within 2 to 3 months. Since this plant is annual, it permanently dies off after a single season and must be replanted each year.

3. Green Dianthus

Green Dianthus

Dianthus barbatus ‘Green Ball’/’Green Trick’

  • Type: Annual or herbaceous perennial
  • Hardiness Zones: 4 to 8
  • Position: Full to part sun

Dianthus is another incredibly popular cut flower. Green Ball and Green Trick have pom-pom-like blooms that are often used as filler alongside more traditional flowers. 

You can tell the difference between these two varieties by measuring the flowerheads. Green Ball plants have flowers larger than 6 centimetres across. Green Trick flowers, however, are smaller.

Dianthus is a tender perennial that may overwinter in mild climates. In most areas, however, it’s more reliably grown as an annual.

4. Kermit Chrysanthemum

Kermit Chrysanthemum

Chrysanthemum x morifolium ‘Kermit’

  • Type: Herbaceous perennial
  • Hardiness Zones: 5 to 9
  • Position: Full sun

Autumn-blooming chrysanthemums (or, simply, ‘mums’) come in a wide range of colours. Perhaps the most unique, however, are green-hued varieties like Kermit.

These flowers are button-shaped and lime green with occasional white flecking. Mums work equally well in both landscape beds and seasonal containers and can be easily overwintered in most climates for several years of blooms. 

5. Green Goddess Calla Lily

Green Goddess Calla Lily

Zantedeschia aethiopica ‘Green Goddess

  • Type: Bulb
  • Hardiness Zones: 8 to 10
  • Position: Full to part sun

Green Goddess is a unique variety of calla lily that features white flowers tinged with green at the tips. The amount of green varies from one flower to the next, with some being almost completely saturated with the colour.

You can grow this bulb in the landscape or in large containers. It’s also a good candidate for areas with damp areas — e.g., a rain garden or water feature border. 

In colder climates, calla lily bulbs may be dug up and stored for winter.

6. Boat Orchid

Boat Orchid

Cymbidium spp.

  • Type: Perennial
  • Hardiness Zones: 10 to 12
  • Position: Bright, indirect light

I’ll be the first to admit that I’ve yet to master the art of growing orchids. But I do know that there are several varieties boasting green flowers, many of which belong to the boat orchid group.

Boat orchids encompass 50 species within the genus Cymbidium. They tend to be more cold-tolerant than other orchids (but that’s not saying much!) and bloom in the winter for weeks or even months at a time. Nearly all gardeners will need to grow these flowers indoors to keep them alive.

7. Green Rose

Green Rose

Rosa chinesis viridiflora

  • Type: Hardy perennial
  • Hardiness Zones: 5 to 11
  • Position: Full sun

Natural green roses don’t really exist. Some yellow varieties can appear chartreuse in the right light, but bouquets featuring this colour are almost always the work of dye. The only exception is Green Rose, which produces green ‘flowers’ via a botanical loophole.

According to the American Rose Society, Green Rose’s unique look comes from a lack of true petals. Each flower is instead made up entirely — from the petals to the reproductive organs — of vegetative tissue.

8. Green Flutter Daylily

Green Flutter Daylily

Hemerocallis sp. ‘Green Flutter’

  • Type: Herbaceous perennial
  • Hardiness Zones: 4 to 9
  • Position: Full to part sun

If you’re looking to add some green to your summer garden, the Green Flutter daylily is reliable and easy to maintain. The flowers are highlighter-yellow with vibrant green throats that almost seem to glow in the right setting. 

This reblooming variety stays just under 2 feet tall when in flower. It would particularly work well in a low-growing border for a patio or stone walkway. I recommend planting Green Flutter in small groups for maximum impact (don’t hesitate to mix and match with other daylily varieties!).

9. Magic Green Amaryllis

Magic Green Amaryllis

Hippeastrum sp. ‘Magic Green’

  • Type: Bulb
  • Hardiness Zones: 8 to 11
  • Position: Full to part sun

Amaryllis can include a wide number of flowering perennial bulbs in the Hippeastrum genus. You’re probably most familiar with the red, pink, or white flowers commonly sold around the winter holidays. Magic Green has creamy green flowers occasionally fringed by hints of red.

This is a jumbo variety that grows up to 2 feet tall and bears huge flowers for several weeks each year. Note that amaryllis naturally blooms in late winter or spring — commercial greenhouses force the bulbs to flower for Christmas sales — and can be planted outside in warmer climates.

10. Green Star Gladiolus

Green Star Gladiolus

Gladiolus sp. ‘Green Star’

  • Type: Bulb
  • Hardiness Zones: 8 to 11
  • Position: Full sun

Also known as sword lilies, gladiolus are summer-blooming bulbs that produce tall, floriferous stalks in a range of interesting colours. Right now, I have a pastel mix planted on my front border. However, I might also try getting my hands on some Green Star corms for next year.

Green Star looks just like any other gladiolus except for its rich, pistachio-coloured flowers. I highly recommend succession planting to extend the display and don’t forget to dig up the corms at the end of the year for storage if you live outside of zones 8 to 11.

11. Little Lime Hydrangea

Little Lime Hydrangea

Hydrangea paniculata ‘Jane’

  • Type: Hardy perennial
  • Hardiness Zones: 3 to 9
  • Position: Full to part sun

As the name suggests, Little Lime is a dwarf panicle hydrangea. This woody shrub is covered in milky green flowers throughout summer that then turns a brilliant shade of pink come fall. 

Little Lime’s short stature makes it ideal for low-growing perennial borders and outdoor containers. I personally like to use this plant in front of larger hydrangeas for depth or as a flowering foreground for tall evergreens.

12. Envy Zinnia

Envy Zinnia

Zinnia elegans ‘Envy’

  • Type: Annual
  • Hardiness Zones: 2 to 11
  • Position: Full sun

Annual zinnias can be tucked between foundational shrubs or even scattered throughout your vegetable beds to attract pollinators and other beneficial insects. While most zinnias boast bright shades of pink, orange, or red, Envy has distinctly green flowers.

This is one of the easiest green flowers to get your hands on since seeds are readily available online. You may even get lucky and find packets at your local independent garden store.

13. Venus Slipper Orchid

Venus Slipper Orchid

Paphiopedilum spp.

  • Type: Perennial
  • Hardiness Zones: N/A
  • Position: Bright, indirect light

Not to be confused with the lady slippers native to North America, these are tropical orchids belonging to the genus Paphiopedilum. There are several types of Venus slipper orchids with greenish flowers.

According to the American Orchid Society, Venus slipper orchids are cared for much the same way as African violets. They don’t need much light and are one of the easier orchids to grow indoors.

14. Green Jewel Coneflower

Green Jewel Coneflower

Echinacea purpurea ‘Green Jewel’

  • Type: Herbaceous perennial
  • Hardiness Zones: 3 to 8
  • Position: Full to part sun

The flowers of Green Jewel have lush green petals surrounding a darker, conical centre. They’re also notably fragrant and quite large (measuring up to 5 inches across).

Like other coneflower varieties, this perennial attracts all types of pollinating insects and birds. It’s best to leave the spent flowers in your garden until the following spring since songbirds will take seeds from the cones throughout late fall and winter.

15. Lady’s Mantle

Lady’s Mantle

Alchemilla mollis

  • Type: Herbaceous perennial
  • Hardiness Zones: 3 to 8
  • Position: Full to part sun

Lady’s mantle is a herbaceous perennial most commonly cultivated for its large, scalloped foliage. In late spring, however, these plants also produce small green flowers in clusters above the leaves.

Use caution when planting a lady’s mantle in the landscape as the flowers self-seed incredibly easily. Also, note that ladies’ mantle is classified as invasive in parts of North America.

16. Spring Green Tulip

Spring Green Tulip

Tulipa x hybrida ‘Spring Green’

  • Type: Bulb
  • Hardiness Zones: 3 to 8
  • Position: Full sun

Spring Green is one of the most popular of the Viridiflora (or green) tulip group. This spring bulb has ivory petals with soft green ‘feathering’ markings.

Tulips look their best when planted in groups. I like to plant many different varieties for maximum impact. When planning out your tulip bed, keep in mind that Spring Green is a late-bloomer that lasts about 2 weeks before fading. 

17. Lime Green Flowering Tobacco

Lime Green Flowering Tobacco

Nicotiana alata ‘Lime Green

  • Type: Herbaceous perennial
  • Hardiness Zones: 10 to 11
  • Position: Full to part sun

Flowering tobacco is an ornamental plant with extremely fragrant flowers and large basal leaves. Most varieties have white blooms but Lime Green boasts uniquely chartreuse-colored flowers.

Though flowering tobacco has an annual life cycle in most climates, it readily self-sows and may return year after year. It flowers for much of the growing season — from summer into fall — and attracts all kinds of pollinators, including butterflies and hummingbirds.

18. Green Glow Azalea

Green Glow Azalea

Rhododendron ‘Green Glow’

  • Type: Hardy perennial
  • Hardiness Zones: 8 to 10
  • Position: Part sun to shade

Whether you’re looking for improved cold tolerance or a reblooming habit, there are countless azaleas on the market to choose from. One particularly interesting variety, Green Glow, has pale green flowers which gradually fade to white.

Green Glow is an evergreen azalea, so offers year-round interest regardless of active blooms. This shrub is an excellent choice for borders and other foundational beds located in light shade.

19. Jack-in-the-Pulpit

Jack-in-the-Pulpit

Arisaema triphyllum

  • Type: Herbaceous perennial
  • Hardiness Zones: 4 to 9
  • Position: Part sun to shade

While many people mistake this North American native for a carnivorous pitcher plant, it is actually closely related to arums like the peace lily or taro plant. Jack-in-the-pulpit is naturally found in woodland areas with acidic soil and shady tree cover.

The botanical flowers of Jack-in-the-pulpits are located on an inner spadix covered by a large modified leaf called a spathe. This leaf is usually green and/or purple. Some plants have striped spathes.

20. Alba Plena Clematis

Alba Plena Clematis

Clematis florida var. flore-pleno, syn. C. florida ‘Alba Plena’

  • Type: Hardy perennial
  • Hardiness Zones: 7 to 11
  • Position: Full to part sun

This interesting clematis has predominantly white flowers with distinct tinges of pistachio green throughout. Most of the Alba Plena’s green colouring is concentrated around the staminodes, but some specimens also have to feather along the petals themselves.

Alba Plena is a Group 3 clematis, meaning that it blooms exclusively on new growth. It’s recommended that you prune Group 3 varieties within a few inches of the ground each year to promote maximum flowering.

21. Sophisticated Lime Green Petunia

Sophistica Lime Green Petunia

Petunia x hybrida ‘PAS933349’

  • Type: Tender perennial
  • Hardiness Zones: 9 to 11
  • Position: Full sun

Petunias come in an impressive range of colours. This chartreuse variety is a great example of how flower breeders have successfully toed the line between green and yellow.

Typically grown as annuals, petunias are a go-to solution for framing garden beds or filling hanging baskets. As they grow, the plants sprawl and spill for a relaxed, floriferous display that lasts most of the season.

FAQs Natural Flower Pigments

What is the rarest flower colour?

Blue is the rarest of all flower colours. This is because plants don’t produce any true blue pigments. Plants with naturally blue flowers or foliage have instead learned to modify red pigments (called anthocyanins) using things like pH and other biological tricks.

Do green flowers contain chlorophyll?

Not only is chlorophyll essential to photosynthesis but it is also an extremely potent green pigment. Chlorophyll is what gives plant leaves their vibrant colour. It is also found in countless other plant tissues, including the petals of some flowers.
