Hydrangeas – the biochemical surprises

Colours of Hydrangeas

Did you ever wonder what differentiates Hydrangeas in their colours? They range from pink to blue, including all shades of lavender to violet and purple, as well as green and white colours. In case you have grown them in your garden, you may have been surprised about the colour that ended up appearing on the bushes.

In fact, the colours of these flowers are not a result of a variety of different pigments as is the case for other flowers, such as roses or tulips. Hydrangea blooms act as a natural pH indicator for the soil in which the plant grows.

When the shrub grows in a very acidic soil, the result of the flower colour is going to be blue. The development of the red and pink colour indicates a neutral to basic soil. An interesting fact is that these flowers indicate the pH with a reverse colour of those for litmus paper.

When it comes to white Hydrangeas, unlike others, they don’t change their colours regardless of the pH of the ground. However, when they get older they can turn blue or pink at the tips. To prevent that from happening, you can use a well-balancer fertilizer that is low in phosphorous and keep the acidic levels of the ground lower.

Important thing to note when growing Hydrangeas is that even though they like the sunlight, they love the afternoon shade. Too much sun and high heat can dry your flowers. As a result they will start wilting and turning brown in colour.
If you are looking for a cooler place for them, try avoiding planting them under the tree. The tree will most likely absorb all the nutrients and harm your Hydrangeas.

Antique Hydrangeas

These flowers have a very specific characteristic of antiquing, that is usually compared with aging. This process starts happening at the end of August and the beginning of September.

The blossoms start changing their bright summer colours into smokey burgundy, faded green, shimmering blues and soft lavender colours, something more suitable for the beginning of the autumn season.

If you are to see these flowers for the first time, you would think that this is another variety of the plant. But note that these types of Hydrangeas are not a separated specie from fresh Hydrangea macrophylla.

In case you are harvesting them from your garden you should know that when the colours start to change, the flowers are still not ready to be cut. You should continue watering your plants and leave the flowers for a little while. If you notice that the flowers are a bit crisp when touching them – it is the time for the harvest!

Antique Hydrangeas will not wilt or die in your vase. They are perfect for those who love to keep their flowers for a longer time on the table.

This time we have decided to go with Hydrangea Sibilla Classic in combination with Gyps my Pink and boy was that a good idea! Hop over to our Instagram page to see a closer look of this Antique Hydrangea and it’s magical colours.

“Charming and kind but serious and very talented. That would be the best description of our new team member. She is one of the leading florists here in The Netherlands, with a long experience in very exclusive wedding and floral arrangements.

We hope that she will be a great example for all our new florists who are still eager to learn. And that you will find her work inspirational enough to apply some of the ideas to your own way of working.” – from Summer Flowers 2021.

The biggest announcement of this week – introducing Sanne! Our source of creative ideas and inspirational work that will be introduced to you on our blogs and social media. Take a moment to give her a warm welcome on our Instagram today!

For this week’s topic, we have decided to go with a few of the lovely garden roses from the collection. Rosa Garden Julietta Spray, Rosa Garden Pinky Pie! and Rosa La Garden Elaine! were used in the arrangement from the photo. For the green, we recommend using Eucalyptus or you can use Sanguisorba Arnhem.
Take a closer look at the flowers on the slider below.

When arranging this bouquet, Sanne showed us the perfect combination of the Julietta and Pinky Pie rose. While Julietta gives you that sharp pink and colourful look, Pinky Pie tones it down with its creamy and soft colours. Not to mention that Pinky Pie buds are so massive and unbelievably beautiful, that your clients will not be able to take their eyes off them. Together they smell incredible which makes them perfect for a wedding bouquet.
In case you want to diversify your arrangement a bit, you can add La Garden Elaine rose as well. It is the perfect addition without making it too colourful.

Our talented florist created another version of the arrangement with Sanguisorba Arnhem. You can see this version on our Instagram story and highlights. Deep red flowers in the shape of small bubbles were popping out of everywhere creating this dramatic and fun look. Definitely a go to flower in case you want to spice it up a little bit.

If you are the type that likes to keep it simple, putting only roses together or adding only a small bit of light coloured Eucalyptus is far good enough. These roses know how to carry themselves and take all the attention!
