I wanted to wait a year before giving my review. The young plant was beautiful, and this year it has lovely buds! Very satisfied.

Description
Hydrangea macrophylla Hovaria® 'Hopcorn' is a recent variety with masses of violet-blue inflorescences. Its sepals are fringed, reminiscent of the shape of the lilac flower. This bush blooms from July to October. Its habit is dense and compact, and it will not exceed 1.2m (4ft) in height. It will find its place in a border, as a standalone plant, or in a large pot on a terrace. Unlike other cultivars, it tolerates sunny exposure well and will show its most beautiful blue in slightly acidic, moist but well-drained soil.
Hydrangea macrophylla Hovaria® 'Hopcorn' is a cultivar obtained in the Netherlands in 1998, among the many cultivars obtained through the cross-breeding of hardy species belonging to the Hydrangeaceae family, native to China and Japan. This dense and compact bush reaches a height of 80cm to 1.2m (32in to 4ft) with a similar spread. From July to October, it produces ball-shaped inflorescences composed of a multitude of sterile flowers with curly sepals, resembling popcorn (hence the variety name). In sufficiently acidic soil, their colour is an intense blue-violet, otherwise they take on a more pink colour. The flowering is accompanied by dark green foliage carried by sturdy stems. This hydrangea is hardy and can withstand temperatures down to -15°C (5°F).
'Hopcorn' is a remarkably original plant, which can be highlighted in the garden, on a terrace, or in the house to create refined bouquets. Hydrangeas, beloved by gardeners, are well known for brightening the north side of houses, but this one will accept sunny exposures. This variety is particularly suitable for container cultivation, which can be placed in a beautiful pot on a terrace or near an entrance, although it also has a prime place in flower beds and as a standalone plant. Even though these plants dislike chalky soil, they are not strictly ericaceous plants. Pair them with Magellan fuchsias or annual impatiens, or plant spring-flowering bulbs in front of their round silhouette. Enjoy their splendid flowering in the garden or in the house for a long time.
Note: The colour of the flowers of macrophylla hydrangeas varies depending on the pH of the soil. Traditionally blue varieties turn pink in neutral or alkaline soil. To maintain a beautiful blue colour, mix ericaceous soil into your garden soil and apply aluminium sulphate (slate contains it) or alum stone every spring.

Planting and care
Plant in spring or early autumn, preferably in a slightly shaded position, for example against an east-facing wall, or even north-facing. In very cold regions, it may be prudent to overwinter it in a cold greenhouse or in the conservatory. Protect it from cold and drying winds. It does not require ericaceous soil, but appreciates deep, moist but well-drained, fairly fertile soil, possibly enriched with a good base fertiliser before planting. If planting near a wall and the soil is dry at its base, place the root ball at least 30 to 40cm (12 to 16in) away from it and incorporate a quantity of well-decomposed compost to better retain moisture in the soil. Very hardy, it can be planted in cold regions without fear.
As for pruning, remove the faded flowers on the first bud or on the pair of buds directly below. When the plant is mature, prune the older stems back to the base by a quarter or a third. This will encourage the formation of young shoots. Carry out this pruning every year during March and April.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
