In this article, we will be discussing in what plants can be used to give cool colours in the container garden.

Since the 1930s when Vita Mary Sackville-West created her famous white garden, designers have sung nothing but praise about the beauty of the monochromic planting scheme (see previous article to know what it entails in making a monochromic scheme).

If you want to achieve a similar effect, you need to plant white producing plants from spring onwards. At that time you can start with hellebores and snowdrops, peaking in summer with peonies, roses and daisies, concluding in autumn with white aster and Japanese anemones.

To some all white schemes appear to be too restrictive, but this can be broken up by including a few blues, purples and pinks, which will blend without appearing to be too harsh.

You can also use the scheme to create a cool, natural backdrop for pastels or warm coloured flowers by using plants with blue and grey leaves, such as Artemisia, Convolvulus and Tanacetum, to reflect the sun and to sparkle in the containers.

What follows are the plants I recommend to use in the cool scheme.

  1. Flowers! They make everyone and anyone happy. These are beautiful flowers and you gave their biological names too. The French Lavender is also called the “Willow Vale”?. I didn’t know that and Lavender is my favorite flower as the fragrance is calming and soothing. It is a great flower to have in your garden. This site is heavenly. 

    1. Hi Sharon

      I try to bring as much colour to people’s  lives with plant suggestions that  matches  a brief. In this case the cool colours. Lavender is a beautiful  flower to have in your container garden and  Willow Vale is a named variety  of Lavender. You see I use a system of the Latin name to help find the plant. The common name for easier pronunciation  and the variety to look for.

      Thanks

  2. Ah, this is very perfect. No body wants to have a container garden that looks all very scanty and ugly and that is why this post is very relevant. You see, while going through your post, I found out that most colours of the plants are purple or white and I remember telling a friend that those wmtwo colours of plants make the best in a garden apart from Green. I would like to know though if the new Jersey tea is an actual tea that one can drink

    1. Hi Henderson

      That is the beauty of monochromatic schemes, as you can use plants with one colour with splashes of another colour to give a wonderful  container display. More choice means more plants can be used. To answer your question  the answer is yes and you can use the leaves to make a tea substitute.  You can blame the Boston tea party for that.

      Thanks

  3. This is a real time education. Not just an ordinary post, but its something that i could say you invested much effort into it. I studied a little bit of Botany in the University and I could see the various plants mentioned in this article. The botanical names are well researched. Great work. 

    The only thing I will add will be the length of the article and the number of plants seems to be much and makes the reading sometimes get tiring. you can categorize the plants in order to shorten the article a bit. But i will not delete any of the content, but rather group them to shorten the article.

    1. Hi Changingworldnews

      Thank you very much for those kind words and constructive feedback. When I write articles I try to give as many suggestion as possible and this include lists of plants that can be grown. I keep my plants in alphabetic order as this is easier to find for my readers. It is up to the individual if you want to read the details about each plant. I always include a description  of the plant, the height it grows up to, when it flowers and its ideal growing conditions.  

      Kind regards 

      Antonio

  4. Sometimes the looks and beauty of our garden matters and the color selection of the plant that are in it makes it better. Personally I am a lover of cool colors and although some of the plants you mentioned here with with flowers are new to me, I am taking your advice on the color selection and the foil. Thank you

    1. Hi Benny 

      You are so right that colours are very important  in the container  garden and that cool colours add great undertones.  Your eyes will be drawn to it and your visitors will be talking about it. It is always good to extend the range and knowledge of what flowers to have in your garden. More plants means more choice.

      Thanks

  5. First of all thank you so much for sharing this wonderful article with us .I plant a plant in my garden whose eyes are attracted to the plants themselves because of the cool colors of the flowers. To me the white flowering plants look great .And I planted the container in the balcony of my house .Also I planted Anemone x hybrida and Anthemis punctata in my garden and it has grown excellently. The flowers look very interesting and the white color to me is a symbol of peace .  These added extra beauty to my home.These two perennial plants are very suitable for the beginning and end of summer .

    In addition I have found some more perennial plants. Looking at the pictures in your article looks very interesting, I will definitely try to put these. And I will pass your article on to my friends. They will also share their new experiences with you. Can I share your article on my social media?

    1. Hi Shanta

      Of course you can share my article with as many people as you wish . The plants that I have selected should give colour for 7 to 8 months of the year, so you can come up with a planting scheme that has colour for that time. You can experiment and find your ideal combination.

      Thanks

  7. Hey, I enjoy a lot while reading on part of a cool colours scheme and find it very useful for everyone. While reading I know that Cool colours are great for those who desire a monochromatic scheme of different tints, hues and shades so that your eye will be drawn to the plants themselves. White flower plants are great in the garden. Thanks for sharing

    1. Hi Deepanshi

      I always think that part of my brief is to get people think about themes and colours is one of the most important ones, as we attracted  by how the scheme looks to the  naked  eye. If it blends or contrasts  well they you scheme will be wonderful and you will not be ashamed to show it off. White colour schemes with splashes of blue or purple gives an appearance  of pureness and that is why most people go crazy for them.

      Thanks

      Thank you for stopping  by and commenting. White is such a pleasant colour scheme that is why most modern home walls are painted magnolia, as they make the space open and inviting. This also applies to the garden as well. The plants I select will meet the cool colours theme very well with added blues and purples to break them up.

      Kind regards
