Iris meanings in different countries

Irises are popular across the world, which means they’ve long held different meanings to different cultures. These include:

Ancient Greek – In Greek mythology, Iris was the messenger of the Gods who communicated via a rainbow – the passage between Heaven and Earth. This is why the iris flower is said to mean communication. The Greek word eiris means “messenger”, from which the flower gets its name.

France – While fleur-de-lis directly translates to “lily flower”, the decorative symbol used by French royalty is actually inspired by the yellow iris flower. During the Middle Ages, the fleur-de-lis appeared on the monarchy’s coat of arms, coins and shields. It’s quite fitting too, as this stunning bloom represents victory, courage and power.

China – In China, iris flowers symbolise spring, vitality, and change. The Chinese sometimes refer to the iris as a butterfly due to its wing-like petals. In Ancient China, the iris flower was seen as a protector and people would place irises in their homes to keep negative energies at bay.

Egypt – Throughout history in Egypt, irises have been seen as a symbol of protection and power. To protect pharaohs as they entered the afterlife, ancient Egyptians placed these delicate flowers on their tombs, which was also seen as a way to pay their respects.

These blooms can easily enhance the artistic style of a wedding arrangement to give your big day a unique look. Whether it’s a refined bridal bouquet or an enchanting table centrepiece, the iris flower is an elegant addition to your big day.

  • Funerals – As its delicate petals wither in the winter and bloom in the spring, the iris is a reminder that bright days lie ahead. Share your condolences with brilliant white irises in the form of a funeral spray or a beautiful bouquet.

  • Perfumes – In the 19th century, iris roots became an integral part of the perfume industry. When left to dry, these roots carry a violet fragrance. This pleasant scent was used in cosmetic products. Today, they often feature in potpourris and sachets.

  • Home décor – The iris flower is incredibly versatile and will flourish in just about any space. Grow them in pots on the windowsill or, if the season calls for it, plant them in the garden as a summery border. A mixture of lucid yellows and exquisite purples will look brilliant in a vase and bring a burst of colour to your home.

Iris care tips

Whether you’ve been gifted a stunning bouquet or have just bought a bunch of irises to brighten up the home, you’ll want them to last as long as possible. Here’s how to get the most from your iris flowers with the right care:

  • Remove any foliage that will be under the waterline in the vase - this prevents the build-up of bacteria in the water. It also prevents any foliage under the water from drinking too much water before the iris flowers.

  • Add any flower food to the water as per the packet instructions.

  • Cut about 3 - 4cm from the stems, make sure you do this at an angle as this improves the water uptake of the flowers.

  • Irises will survive best without being too hot or cold. So it’s best to keep them out of direct sunlight and away from heat sources.

  • Change the water once it starts to look cloudy and re-trim the stems for increased longevity.

  • Keep an eye on the water level as irises are very thirsty flowers.

  • Note that irises are toxic to cats, so make sure you place them out of reach of your furry friends.
