10 Mauve and Purple Flowers for Your Garden

Diana was a member of the Royal Horticultural Society. She & her family all love gardening. She enjoys photographing & painting plants too.

I love to grow plants in my garden in matching tones. They won't all be the same color, but there will be a definite theme in certain areas of the garden.

Nearly all the photographs of purple and mauve flowers shown below are pictures of plants in my own garden.

Choose Your Colors Carefully

Some gardeners like a profusion of multi-coloured bedding plants with an orderly row of low-growing plants in front, but I prefer blocks of colour.

I don't believe that just because it's a natural mixture of colours it must be good—I think one can improve on nature, and this is what I would like to show you here.

A tasteful blending of tones is what I like to go for. A few contrasting flowers, yes, but a mish-mash of "anything goes," certainly not!

You will also find here a useful reference book with a gardening theme and a video for the artists among us who would like to improve on their skills.

A thing of beauty is a joy forever.

Lynchnis coronaria or rose campion.

1. Lychnis Coronaria

Also known as rose campion, Lychnis coronaria is one of my favourite plants, with silvery-grey silky leaves and small, bright cerise-to-mauve flowers.

Lychnis flowers in summer, and the colour of the flowers is so intense that they are almost luminous. They grow about 1.5 to 2 feet (46 to 61 cm) high, the branching stems bearing numerous flowers.

If you snip off the flower heads after they have died, the plants continue to flower prolifically throughout the summer.



2. Lavatera

Every year, I cut my lavatera right back, almost to the ground, and the following year they grow up about 10 feet (305 cm) tall with a wide spread. They are a lovely pinky-mauve colour and look good with other plants in the same colour spectrum—I grow mauve wild geraniums, pink phlox and purple lavender next to them, and they look heavenly all summer.

They start flowering in late spring or early summer and will normally continue into late autumn or early winter. If the winter is mild, however, they will continue to flower until January—mine did that.

3. Black Lily

Although it's called Black lily, you can see from the picture that it's actually purple.

This is a spectacular, shade-loving plant with beautifully shaped leaves that appear in spring and die back in summer, and grow to a height of 2 to 3 feet (60 to 90 cm). The flower has a definitive lily shape, with Gothic connotations because of the gloomy colour.

There are two drawbacks if you are considering growing this plant:

  1. It has a potent, unpleasant scent (which actually attracts pollinator flies); and
  2. The flowers only last for two or three days, one week at most.

Nonetheless, I think it is worth growing for its interesting characteristics.

Purple clematis.

4. Purple Clematis

Clematis comes in a wide variety of colours and shades, from whites and pinks to blues and mauves.

The roots need to be in the shade, but the rest of it likes sunshine (as it is a climber, this is not a problem). You can just plant it at the back of the garden border along a sunny wall or fence where bottom of the plant is protected by other plants growing in front of it.

This didn't work too well for me last year, however, as it was behind a huge and healthy lavatera (the one you see in the photograph above), and the beautiful purple clematis flowers in bloom could hardly be seen.

This year, I am growing some more clematis up a trellis on a wall next to my lounge window, so that I can look out and see it . . . heavenly!

5. Ajuga Reptans

With its purple flowers, Ajuga reptans is good for ground cover. It is an attractive, low-growing plant. It grows to a height of 4 to 14 in (10 to 35 cm) with deep purple flowers and mauve leaves, and spreads quite well.

Ajuga tends to dry out in hot weather, so it needs to be watered in summer. It has a very long flowering period, and the small flowers just keep coming.

I grow it in my rockery and at the front of the flower border as ground cover.

This is the white garden at Sissinghurst, a famous English monochrome garden.

What About Monochrome Gardens?

Sometimes, gardeners get a bee in their bonnet about rather advanced garden design, such as growing only plants of one particular colour—for example, the famous white garden at Sissinghurst in England.

One of my friends is trying to do just this, but it is quite difficult to completely clear your garden of colour and just plant white flowers, whilst still ensuring there are flowers throughout the flowering season. Does this idea appeal to you?



6. Verbena

Verbena is a plant with small flowers that can grow very tall. The verbena above has flowered all summer, and even in mid-November, there are still flowers in bloom. I planted it in the wrong place though—at the front of my rockery—whereas it would look better flowering towards the back of a border.

You may wonder why I planted such a tall plant where it towered over all the other flowers and plants. There was some logic: I thought it was the shorter variety of verbena, which grows to a height of about 9 inches (23 cm). I never realized there was a tall variety called verbena bonariensis that grows up to about 5 feet (150 cm) tall. They look very pretty in a group of them planted together.

Thinking forward, it would look particularly gorgeous in with yellow verbascum, which is also tall, and a few tall grasses and eryngium and echinops to emphasise the tones of purple. You can just see my verbascum quite a bit further back, in the centre of the picture. That was also in the wrong place, being far too tall to stand in the rockery.



7. Hellebore

There are many different varieties of hellebore. The one in the picture is a rather special one that I bought from The Royal Horticultural Society.

Hellebore is a perennial. When the leaves turn brown, you can just cut them back, and maybe keep some of the seed pods to plant. They grow to a height of 1- 3 ft (30 cm to 1 m) depending on the variety.

Be careful though, because you can get an allergic skin reaction from contact with the sap from the seed pods. So don't handle them for more than a couple of minutes, and wash your hands afterwards.

(Note: I once had very serious poisoning from large white hellebores. I have written about it and you can see the photographs in Poisonous Plants: Hellebore, Oleander and Vinca or Periwinkle.)



8. Osteospermum

Osteospermum is a daisy-like flower and comes in several colors. I chose the one shown in the picture for my garden because I love the delicate shades of pale mauve to white, with grey undertones.

The petals open up in sunlight and close when the sun goes down, or when the weather is not very bright. I love to see the variations in a single day—if I get up early at dawn and go out to see it, the petals are quite tightly closed.

Osteospermum is an easy plant to grow and just needs to be deadheaded as the flowers fade, in order to encourage more flowering. Then cut them back once flowering has ceased in winter, to make a nice compact plant for the following year.

It flowers over a long period of time and seems to be happy in full sun or partial shade, height up to 20 inches (50 cm).

Vinca or periwinkle.

9. Periwinkle

Also known as vinca, periwinkle is a low-growing plant, which makes it good ground cover.

It has shiny dark green leaves and beautiful purple flowers in spring, and continues flowering sporadically throughout the rest of the year. Vinca Minor has smaller flowers and leaves 3 to 6 inches (7 to 15 cm) in height and Vinca Major is a larger plant 6 to 18 inches (15 to 45 cm), but looks similar.

Periwinkle will grow under trees. If you are not careful to restrict its growth, it will cover a rockery completely in about three years.

Hostas are mainly popular for their decorative leaves.

10. Hosta

Hostas flower briefly in late summer in wonderful shades of purple and white but are mainly grown for their ornamental leaves. They grow up to a height of 2 feet (60 cm) with a wide spread.

These purple flowers look beautiful, but my hostas mostly get eaten by slugs, so the flowers last for even less time than they should. It only takes one slug or snail to escape from my various slug treatments, and leaves and flowers are gone in a night.

I like this photo of a hosta in full bloom, which I took in my garden, but it is certainly not representative of the sort of hostas I grow, which usually look a bit sad.

How Do You Like to Organize Your Garden?

Do you like to have large color blocks of similar shades, or do you like to mix your borders?

I sometimes have mine changing to different swathes of color as the seasons change: starting off with yellow daffodils in spring, then lots of pink and white in summer, followed by orange and red in late summer and finally back to pink again, with a few bright orange nasturtiums and red cotoneaster berries until the cold weather kills them off.

How to Paint Purple Flowers

Questions & Answers

Question: I want to paint a brick garden wall deep lavender with trellis on the top half. What do you think?

Answer: It would look unusual, but this is no bad thing. It would not be to my taste, but everyone is different, so go by your own feeling about it.

If it was me, and I was unsure, I would take a photograph of the relevant area, and then, using Photoshop or some similar photographic programme, I would color the wall the deep lavender tone you have in mind, and then consider whether to go ahead with that particular colour, making sure that any plants you grow there have flowers that look good against that color.

I have an area of garden that needs some work done to it. I think the Lavatera, Lychnis and Periwinkle would probably good choices for it, possibly with clematis over the fence to provide a bit of privacy. Thanks for the suggestions.

Cynthia Sylvestermouse from United States on May 02, 2019:

I guess I love almost all flowers, but I admit, I have a special place in my heart for purple blooms. You have certainly featured some lovely selections. I find I just might need that black lily!

CCStahl on March 17, 2019:

I love playing off different shades in the same color scheme. I generally don’t like a riot of all kinds of colors. Sometimes it can work, but if if doesn’t it looks too busy and it can clash,

.I love deep purple against vibrant orange, it’s just visually striking. Thanks for your article.

Jennifer P Tanabe from Red Hook, NY on September 24, 2014:

As a purple lover I should really make a plan to get more purple in my garden!

Diana Grant (author) from United Kingdom on July 15, 2014:

@burntchestnut: Yes, it's lovely. We used to grow it in Africa, and I have also grown it in London, on the sunny side of my garden, trailing up a fence

burntchestnut on July 15, 2014:

I haven't heard of the Black Lily before. I think the purple passion flower is pretty. They usually grow in a hot climate.

GrammieOlivia on July 12, 2014:

I have lots of these in my garden and lots more......

Diana Grant (author) from United Kingdom on May 19, 2013:

@masunyoananda: That's great, thank you.

masunyoananda on May 18, 2013:

Very interesting lens, learned a lot which I didn't know here...Blessed...:)

Diana Grant (author) from United Kingdom on November 04, 2012:

@sharonbellis: Yes, I love it too. It looks good with an occasional splash of orange, too

Sharon Bellissimo from Toronto, Canada on November 03, 2012:

I love the colour purple in the garden it's very eyecatching.

Diana Grant (author) from United Kingdom on November 03, 2012:

@Ramkitten2000: Yes, I think it can be very effective. I have a friend who was aiming for a completely white-flowered garden, like Gertrude Jekyll's White Garden at Sissinghurst, but, with so many other beautiful colours, I'm not sure I would want just white. Various shades of pink to dark purple would be more my preference.

Deb Kingsbury from Flagstaff, Arizona on November 03, 2012:

I really like gardens--or individual beds--that focus on a range of shades of a certain color. All flowers are beautiful, of course, but I love the look of, say, a dozen different purples, from light lavender to deep royal purple to reddish-purple. This is something I plan to do when we build our new home in about a year. And having a monochrome flower garden keeps me from getting totally overwhelmed by all the choices there are at the garden store, because I can say, okay, I'm just looking for purple flowers. But as I see here, there sure are a lot of those!
