Hydrangea flowers turn green

Light colored hydrangea flowers have a special feature: they are initially green when they bloom, then turn pink or white and turn green when they fade. How long the flowers look fresh and colored depends on the temperature and soil moisture. In a rather cool summer, the hydrangea can show colored flowers for many weeks while in hot and dry weather it has almost only green colored flowers. But this is also what makes the plants so attractive, as the mixture of green and colorful flowers gives the plant a very romantic note.

Why do the flowers turn green

Due to its green color, the hydrangea is able to produce energy-rich substances from sunlight for some time. Therefore, you should only break out the flower umbels when they have completely bloomed.

New cultivars bloom green

Monochrome green blooming hydrangeas are special cultivated forms that have enjoyed increasing popularity in recent years. They look particularly noble and luxurious and harmonize very well with hydrangeas in strong colors.

The hydrangea stays green and only leaves leaves

If the hydrangea sprouts vigorously in the spring, but does not display any flowers, you may have grabbed the secateurs too bravely in autumn. Most hydrangeas lay the flower buds on the wood of the previous year. If you cut back the hydrangea too much in autumn, you will inevitably separate these flower bases and the hoped-for abundance of flowers in the following year will not materialize.

Therefore, if necessary, you should prune the hydrangea back in spring and only carefully break out what has been lost. You can also leave the bloomed inflorescences on the bush during the winter. Covered with hoarfrost, these are an attractive garden ornament in the cold season and also protect the hydrangea from frost damage.

Tips & Tricks

Hang the hydrangea flowers, which have turned green again, upside down in a shady place. They stay in good shape and fade a little more, which gives the dried flowers a fragile appearance.
