These evolving-flower hydrangeas allow for the creation of new plant scenes over the days, ensuring you never tire of them.

Here is our selection of 5 hydrangeas with evolving flowers suitable for all types of gardens. Discover our varieties to grow in the ground or in pots, in shade or in sunlight.

Hydrangea paniculata ‘Petite Star’: an evolving variety that is wider than it is tall

‘Petite Star’ truly lives up to its name: a small silhouette, but a grand spectacle in the garden during summer! From June to September, this hydrangea produces an abundance of paniculate rounded and dense flowers. Initially lemon green, they take on cream-white hues, then pink, before turning red.

It is the thermal amplitude that causes this colour change in the flowers of hydrangeas paniculata: the more there is an alternation of cool nights and warm days, the more intense the variations will be.

The flowers are not the only ones to see their shades evolve, as the green foliage will turn yellow in autumn.

‘Petite Star’ is unique in being wider than it is tall: this hydrangea measures 55 cm in height and 95 cm in width. Its compact silhouette and small dimensions make it suitable for small spaces or pot cultivation. Very tolerant, it will thrive in both partial shade and full sun, in ordinary soil. Just ensure to keep the substrate cool (moist) in summer to achieve a beautiful flowering.

Hydrangea macrophylla ‘Magical Ruby Tuesday’: flowers with astonishing changing tones

‘Magical Ruby Tuesday’ is part of the ‘Magical’ hydrangea series, whose hues systematically evolve over time. We have chosen this variety for the originality of its colour. The flowers form true red pom-poms at the time of flowering. They then take on shades of grey, black, and pink, before turning bright green.

These colours succeed one another throughout the summer, from July to September. The fading is equally poetic, offering softer pink and green tones, with flowers taking on a paper-like texture.

The dark green ovate and dentate foliage serves as a backdrop to this magnificent evolving flowering.

Of course, these flowers will shine in both fresh and dried bouquets. This modest-sized hydrangea (approximately 1.2 metres in height and spread after several years) will fit in anywhere in the garden. Plant it in a mass, as a border, or in the foreground of a flowering hedge. In a pot, it will brighten up terraces and balconies in the shade without monotony. Note that, like all Hydrangea macrophylla, it does not appreciate being grown in calcareous soil.

Hydrangea quercifolia ‘Ruby Slippers’: flowers and foliage with evolving colours

‘Ruby Slippers’ is a variety of oak-leaved hydrangea. Its flowering occurs from June-July to October, when it produces large panicles of flowers nearly 20 cm long. Their colours become increasingly vibrant over time: first cream-white, they then take on pink hues before turning ruby red.

The foliage is equally impressive as it also offers an evolving colour. Initially green, the leaves turn in autumn, taking on brilliant mahogany and burgundy shades. The bark of this bush also exfoliates over time, revealing a shiny cinnamon colour that is very aesthetic. A variety of hydrangea that keeps the garden interesting!

With modest growth and a compact habit, it will reach only 1.2 metres in all directions after several years. This hydrangea will find its place in the ground, or on the terrace and balcony. Its robust silhouette also allows it to withstand wind and rain well.

Not demanding, Hydrangea ‘Ruby Slippers’ will thrive in partial shade or full sun, in ordinary soil. It even tolerates occasional drought and small amounts of lime. A low-maintenance variety to discover!

Hydrangea paniculata ‘Early Sensation’: an early variety that transitions from white to pink

The variety ‘Early Sensation’ is notable for being early, flowering earlier than most hydrangeas. From the end of June, it reveals a generous flowering in long panicles of nearly 25 cm. The flowers are initially white, before taking on shades of a lovely soft pink. Thus, the shrub showcases young white flowers alongside older pink ones, creating a true bicolour spectacle that lasts until October.

The foliage, initially dark green, takes on autumnal colours at the end of the season before falling.

‘Early Sensation’ is a variety with very delicate colours, perfect for adding a romantic, natural, or refined touch. Its flowers will also be ideal for creating beautiful bouquets.

In terms of shape, this evolving-flowered hydrangea reaches about 1.5 metres in all directions at maturity. It forms a bush with sturdy branches, well able to support the weight of the numerous panicles during summer. In partial shade or light sun, it will thrive as a standalone or in a large container. It is also a good candidate for seaside gardens, as it tolerates salt spray.

Hydrangea paniculata ‘Pastelgreen Rencolor’: a flowering with soft hues

‘Pastelgreen Rencolor’ can be described as a multicoloured hydrangea. From July to October, it presents an avalanche of colours that reveal themselves, intermingle and follow one another on its flowers. Initially white like clouds, they take on green, then pale pink and bright pink hues. Each flower creates its own colourful tableau to delicately adorn the garden throughout the summer.

Another characteristic of this hydrangea lies in the shape of its flowers: Hydrangea paniculata typically displays cone-shaped panicles, while ‘Pastelgreen’ forms adorable coloured balls.

The green foliage turns yellow in autumn before disappearing.

A compact and sturdy bush, this hydrangea, measuring about 1.2 metres in all directions, will find its place effortlessly in the garden or in a pot.
