The magical phenomenon of colour changing flowers

There are many plant phenomena out there that would make you squeal with excitement. Codariocalyx motorius, for example, is named the ‘dancing plant’ because its rapid movements are actually visible to humans. Meanwhile, Pleopeltis polypodioides is known as the ‘resurrection fern’ because it can go for 100 years without water and spring to life when it is rehydrated. But what about plant phenomena that you can grow in your back garden?…

Colour changing flowers are very much available to the everyday gardener. And no, I’m not talking about that experiment you did in primary school where you put a cut flower in inky water to see its petals change. The colour changing flowers I’m talking about actually change colour throughout the seasons while they’re happily growing in your flower beds! 

Check out Dianthus Million Kisses for amazing colour changing power – more on this collection further down!

Why do some flowers change colour?

If you get bored with routine and like to change up the colours in your garden every so often, colour-changing flowers will actually do the work for you! But why do some plants change colour? There are several reasons:

  • Maturation – Some plants will change colours to tell pollinators that they are past the pollination stage. Hibiscus mutabilis, Viburnum opulus and Rosa ‘Mutabilis’ all exhibit this behaviour.



  • Environment – The type of nutrition used and the pH of the soil can affect the colour of flowers. For example, hydrangeas can grow blue, pink or purple flowers depending on how acidic or alkaline the soil is.


 

  • Viral infections – Certain infections in certain plants can actually cause aesthetically pleasing results! This is especially notable in tulips, which are famed for their stunning colour palettes and patterns.

  • Seed/genetic variability – Depending on the breeding that leads to a certain plant’s creation, it can produce different coloured plants from its seeds. For example, a brown pansy could produce yellow or even purple offspring.


  • Season – Repeat flowering plants will often produce a different colour flower in summer to the ones produced in spring. This is the plant’s reaction to the temperature of the season.

 

Dianthus I Love U

Colour changing Dianthus

Looking for a unique plant to create a colour changing effect in your garden throughout the year? There are many varieties of Dianthus that have this characteristic, bringing joy to your yard all summer long! One collection in particular – Dianthus Million Kisses – features five perennial cultivars displaying a range of single and double blooms, bi-colour and colour-changing flowers.

 

Dianthus Early Love

The cultivars are:

  • Pink Kisses – lightly scented deep pink double blooms which fade to softer pink around the edges with age to create a two-tone effect
  • Early Love – double blooms in raspberry red with a deep burgundy centre and a sweet, spicy fragrance
  • Purple Wedding – strongly scented semi-double pink and red two-tone flowers
  • Peach Party – scented soft peach flowers that develop a dark red eye with age
  • I Love You – sweetly fragranced colour-changing double blooms with wavy edges, that turn from pink to pale pink and finally to white

Can you detect a theme?!
