Hydrangea 'Endless' (Hydrangea macrophylla) - garden hydrangea - 14 cm pot - Height 25 cm

Yes, the Endless Summer Summer Love Red hydrangea (Hydrangea macrophylla) is hardy and easily withstands the winters in the vast majority of French regions, down to around -15°C depending on conditions. The Endless Summer series was specifically selected for its superior cold tolerance compared to classic macrophylla hydrangeas. In mountainous areas or regions with very cold winters, a light mulch around the base and, if necessary, a winter fleece over the branches are sufficient to protect it.

The Endless Summer Summer Love Red hydrangea develops large corymbose flower heads in intense ruby to deep red hues, sometimes tinged with dark pink depending on the soil pH. The more acidic the growing medium (pH below 6), the more saturated and deep the red and burgundy tones; more neutral soil can shift the colors toward fuchsia pink shades. The color may also change late in the season, turning toward copper or dark burgundy tones as autumn progresses. These large, generous flower heads remain decorative even after blooming, drying on the plant throughout the winter.

The essential difference lies in the blooming: unlike classic Hydrangea macrophylla hydrangeas, which only bloom on the previous year's wood, the Endless Summer Summer Love Red blooms on both old wood and new wood produced in the spring. This means that severe pruning, a late winter, or spring frosts do not prevent the season's bloom, as new flower buds form on the current year's shoots.

To create a flowering hedge with 'Hydrangea Endless Summer Summer Love Red, allow a spacing of 80 cm to 1 m between each plant so that the clumps can grow freely and eventually join together without crowding each other. Choose a partially shaded location, sheltered from drying winds, and prepare the soil by generously enriching it with compost or potting soil. Plant preferably in autumn or during frost-free periods in spring, watering thoroughly at planting and then regularly during the first season. Such a hedge creates a colorful, nectar-producing plant barrier that offers a change from the uniform green of conifer hedges.

Use a rich, well-draining, and slightly acidic potting mix (potting soil for hydrangeas or rhododendrons). In a pot, 'watering must be more frequent than 'in the ground because the potting mix dries out faster: check the 'moisture every day during heatwaves.

T'Hydrangea Endless Summer Summer Love Red begins blooming at the start of s'ummer, usually in June, and can continue until'October depending on the climate and growing conditions. This exceptional longevity is the hallmark of the Endless Summer series: blooming on the old wood f'irst, then on the new growth of t'he year, the plant produces successive waves of flowers throughout the warm season. Regular applications of f'lowering fertilizers and consistent watering during hot spells further extend the blooming period.

To achieve deep ruby and burgundy tones on the 'Endless Summer Summer Love Red hydrangea, maintain acidic soil with a pH between 5.5 and 6. If your garden has alkaline or neutral soil, incorporate powdered agricultural sulfur, blonde peat, or heather soil at planting.

In pots, opt directly for a hydrangea or rhododendron potting mix, which is naturally acidic.
