When you think of green in the garden, you probably think of leaves and foliage rather than flowers. But there are a surprising number of plants that have green flowers too. Sometimes these are younger blooms before they change colour to white. Other times the petals on these blooms will stay entirely green. Explore these 15 beautiful green flowers to grow and enjoy in your own garden.

The appeal of green flowers

Green flowers are considered unusual and have a certain appeal because of their uniqueness. Different shades of green flowers and folliage look stunning together, whether in the garden or in a floral arrangement. Green flowers are also a popular choice for wedding flowers or events with a natural colour scheme.

In this post I’ll share 16 of my favourite green flowers, many of which I grow in my own garden.

Cymbidium orchid

Green cymbidium orchid flower

Cymbidium orchids – sometimes called boat orchids – are one of my favourite flowering plants. They have long strappy leaves and produce spikes of spectacular flowers. There can be as many as 8 to 12 flowers on each stem. The blooms will last anywhere from 4 to 12 weeks, and can be cut and displayed in floral arrangements. They are also popular bridal flowers.

This beautiful green Cymbidium orchid was gifted to me by a family member, so unfortunately it doesn’t have a variety label. Popular green cymbidium orchid varieties include “Limelight” and the cascading varieties “Green Gables” and “Green Falls”.

Some people consider orchids hard to grow, but I have 5 potted orchids near my door that I find quite easy to maintain. Cymbidium orchids need bright diffuse light, but will burn if exposed to too much direct sun. They also don’t like frost.

Orchids need an airy growing medium, so I use a special orchid potting mix which contains bark. It’s important to water regularly. Never let the growing medium dry out completely. They also need regular fertiliser, especially in the growing season in spring and summer. I add weak liquid fertiliser to the watering can each time I water in summer and less often in winter. You’ll find expert tips on feeding your cymbidium orchid from the American Orchid Society. With regular care your cymbidium orchid will reward you with beautiful green flowers.

Chrysanthemum

Here in Australia, Chrysanthemums are a flower most often associated with Mothers Day in May. Chrysanthemums come in all different shades, including white, yellow and pink. but green ones are rather special. They also come in many different shapes or classes. Green Chrysanthemum varieties include ‘Kermit‘, ‘Code Green’, ‘Green Mist’ and ‘Ping Pong’ (a unique ball shaped Chrysanthemum).

Chrysanthemums (also shorted to just ‘Chrys’ or ‘Mums’) are perennials and are easy to grow. They need full sun, fertile well-draining soils and need regular watering, especially in the growing season. Be careful not to overwater, as this will cause the plants to become waterlogged and rot.

Green chrysanthemums look beautiful in garden borders and also grow well in pots and containers.

Bells of Ireland

Also called shellflowers, Bells of Ireland (molucella laevis) are a beautiful emerald green colour. The flower itself is actually very small and white, and the green calyx around the flower creates the spectacular green bells.

These flowers date back to the 16th century and are in fact edible. They also have a slightly sweet scent. Bells of Ireland wall last up to 2 weeks as a cut flower or can be dried to last even longer.

Bells of Ireland are an annual plant and grow to about 90 cm/35 inches in height. They are a temperature sensitive plant and can’t withstand frost or extreely cold temperatures.

Grow Bells of Ireland in a garden bed or in pots and containers for a lovely show of green.

Clematis

The beautiful climbing clematis is another favourite in my garden. These also come in a rage of colours, commonly white, pinks and purples, but there is a variety with entirely green flowers. This lovely clematis is the double flowered ‘Green Passion’.

The best climate for clematis is a cool, temperate one. These plants don’t do well with heat. Green Passion will flower in late spring and early summer, with a second flush of slightly smaller flowers at the end of summer.

Green Passion will grow to about 2m /6.5 feet tall. Clematis needs a support to attach its tendrils to as it climbs. If you don’t have space for an arbour or a trellis in your garden to grow your clematis on, try growing in a large pot with a support frame.

Wherever you grow clematis, it needs a moist fertile soil. You’ll have the best chance of more beautiful green flowers if you plant clematis with roots in the shade and the flowers in the sun. There’s no need to prune this variety of clematis, but if you need to, a very light prune in early spring is enough.

Anthurium

While more commonly known for the red variety, Anthurium can also have green flowers. Anthurium flowers are actually not flowers, but a ‘spathe’ or modified leaf. The Midori anthurium is completely green. It makes a beautiful house plant and cut stems are a great additional to tropical flower arrangements.

Anthurium plants are tropical, so make sure to water regularly. However make sure that the pot they are in has good drainage so the roots don’t rot. Anthuriums like diffuse light rather than direct light, to avoid burning. Our anthurium loves being in our bathroom, which has lots of light and a stable temperature to keep it happy. Feed with a slow release fertiliser, especially before the growing season.

Green Goddess Arum Lily

Unlike usual white Arum lilies, the Green Goddess Arum lily (Zantedeschia aethiopica) has wonderful green variegation. These evergreen lilies have beautiful dark green leaves and produce tall stems of cream and green in late spring and early summer.

Arum lilies love a naturally damp part of the garden. I grow them among ferns in a cool, shady spot. They do tend to die back in hot, dry weather and become dormant, but will grow back when the weather changes and the soil becomes moist again.

While they are a statement plant in the garden, you should be ware that Arum lilies – including Green Goddess lilies – are considered an invasive species in some countries.

Dahlia

Dahlias are a wonderful perennial flower to include in your garden. They are available in many different forms and shapes, include single and double blooms. And Dahlias can be a huge range of colours, including green. “Envy” is a popular lime green Dahlia.

Plant Dahlias in full sun in well drained soil. If you live in a warm climate like I do, you can cut back your Dahlias after flowering and leave them in the ground until next year. In cooler climates you may need to dig up the bulbs over winter and replant.

Dahlias are easy to grow and make wonderful cut flowers with their long stemmed blooms.

Hellebore

Green hellebore flower

I love Hellebores, also known as winter rose or lantern rose. Our shady garden is home to many varieties, in shades of white, pink and purple. But I love the green hellebores the most. There are Hellebore varieties that stay entirely green and others that start with pink variegation and fade to green over time.

Hellebores need a fertile moist soil and like partial shade. When planting Hellebores, don’t plant the crown of the plant to deep in the soil. A great place to plant them is in a raised garden bed so that you can see the flowers from underneath, where they really shine. As a perennial plant, you’ll enjoy Hellebore flowers from late winter through to early summer for many years.

Carnation

Carnations (Dianthus caryophyllus) are sometimes thought of as an old fashioned flower, but I don’t think that reputation is deserved. They have attractive fringed petals, a lovely fragrance, and come in an array of colours including green.

Originating in the Mediterranean, Carnations thrive in temperate climates but have adapted to grow in more diverse temperatures. They love a fertile, well-drained soil that is slightly acidic and need some sun (full or partial).

Green carnations are a lovely cut flower and a favourite for wedding flowers.

Hydrangea

Green hydrangea flower

With so much shade in my garden, I love to grow hydrangeas. These small to medium size shrubs can grow as high as 2m /6.5 feet and have spectacular flower balls in summer. what we know as hydrangea flowers are actually the sepals, so they all start out as green and change as they mature. Hydrangeas can also fade to green as they age.

Hydrangea colours are genetic but can vary depending on the acidity of the soil they are grown in. Acidic soils produce deep blues and purples, alkaline soils produce pink flowers, and white will stay white regardless of the soil. Green hydrangeas are usually just mess mature white flowers, but there are also some varities that have been bred to stay green, such as ‘Limelight’.

Hydrangeas need some sun but are best with early morning light, as they can burn in direct hot afternoon sun. They also need regular watering, at least 3 times a week in summer. Soak the plants at the roots rather than spray the leaves and flowers.

One of the great things about hydrangeas is that they are very easy to grow from cuttings. So when you prune back hydrangeas in Autumn (back to a string double bud), save some cuttings and place in a pot with some good quality potting soil. You’ll have more hydrangeas to plant out in your garden in no time.

Green Rose

Roses are known for their beautiful vibrant colours, but green roses are quite unusual. They do grow naturally, but are often grown specifically for florists. Rose varieties with green flowers include ‘Greensleeves’ (which starts with pink buds that open to pale green), ‘Mint Julep‘ and ‘Super Green’.

Roses need a sunny place in the garden and can also be grown in containers. Treloar Roses in Australia has a very useful seasonal care guide for roses.

As well as being a beautiful addition to the garden, green roses make wonderful cut flowers.

Lady’s Mantle

Green Lady's Mantle flowers

Lady’s Mantle (Alchemilla mollis or Alchemilla vulgaris) is an easy to grow plant with lovely grey green leaves. It produces small yellow green flowers in late spring and early summer.

Plant Lady’s Mantle in your garden for an attractive border or edging plant, or even use it as a ground cover. Lady’s Mantle needs moist fertile soil and likes some sun, although does better in partial shade in hot climates.

This is an interesting green flower to add to bouquets to add greenery to floral displays.

Mediterranean Spurge

Mediterranean Spurge is a variety of Euphorbia that produces tall yellow green flower spikes in Spring. They can grow to 90-120cm /3-4 feet in height. I have these showy plants growing behind a small hedge to add colour and interest to a garden bed.

A very hardy and pest resistant plant, Mediterranean Spurge loves full sun and well drained soils. It is a drought resistant plant so a great addition to water wise gardens. Spurge also attracts beneficial insects and butterflies to the garden.

This green flower is best kept in the garden as the milky sap from the leaves and stems is poisonous.

Snowball (Guelder-Rose)

Green snowball Guelder-rose flowers

Snowball plants or Guelder-rose (viburnum opulus) is usually white. Hence the snowball name. However, these small flowering shrubs produce flowers that start off a beautiful pale green colour. They stay green for quite some time before maturing to full size white flowers, so I think they still qualify as a green flower. When picked in their less than fully mature state, the green snowball blooms look wonderful in floral arrangements too.

Guelder-rose plants like moist, well drained soils. They can tolerate full sun to full shade (and I have them in both in my garden). They grow up to 2m / 6.5 feet tall and spread more than their height. They don’t require much pruning, just a light trim to shape.

Snowball plants look lovely in borders in the garden. In Autumn this deciduous shrub will put on a beautiful display of red leaves and berries.

Green Tulips

While I do have tulips in my garden, I unfortunately don’t have any green ones yet. Green tulip varieties include ‘Green King’, with all green petals, and ‘Spring Green’, which has largely cream petals with a lovely green feathering.

Tulips grow best in full sun and in well drained fertile soils. They usually flower in late spring. I like to plant tulips in groups, or mixed in with other bulbs. You can also easily grow tulips in a pot, which makes them very easy to to keep track of.

Be aware that tulips are toxic to pets and can cause contact allergies for some people.

Zinnia

Zinnia’s are a spectacular bloom, especially when they are brilliant lime green in colour. The most common green Zinnia variety is Zinnia Elegans ‘Envy’, with beautiful semi-double green blooms.

Zinnias are a flowering annual with summer flowers up to 60cm /23 inches tall. They are very easy to grow from seed or seedlings in garden beds or in pots. Plant Zinnias in full sun. They are perfect for garden borders and for long-lasting cut flowers.
