ADR Graden Merit Value-for-money
A miniature climber growing to no more than 2 m in height, it repeats flowers well and is disease-resistant. Its roses are semi-double, open-cupped, opening in purple and turning lavender-pink around a white eye surrounding a heart of golden stamens—a lovely addition to trellises, pergolas or small obelisks in the ground or pots.

Description

The 'Perennial Blue' Rosebush is a climbing mini-rosebush, a recent creation that combines many qualities. It will please with its compact size, less than 2m (7ft) tall, which allows it to fit anywhere, but also for its floribundity, beautiful reblooming and excellent resistance to diseases and cold weather. From June to October, hundreds of miniature semi-double roses with open cups bloom in a vibrant colour. They open in a rather purple shade and fade into lavender pink, revealing a white eye that encircles a golden stamen heart. It will make a beautiful decoration for a trellis, a pergola or a small column in the ground but also in a large pot on the terrace.

This modern climbing hybrid rosebush is a creation by Bernard Merhing, who was born in 2007. In its flowers, a little violet-mauve, semi-double, one can recognize the parentage of the excellent variety 'Veilchenblau', but one can also find in its genes the temperament of Super Excelsa, an extremely floriferous David Austin rosebush, very reblooming, offering small magenta, double roses. This wonder shows an upright and flexible habit. It will quickly reach (in 2 or 3 years) 1.80m (6ft) to 2m (7ft) in height, sometimes a little more, with a spread of 60 to 90cm (24 to 35in), depending on the growing conditions. Its long stems are flexible and covered with dark green foliage, resistant to diseases. The flowers of this climbing rosebush, with very reblooming flowering, form in June-July, then in successive waves until October. They are born on short shoots of the 2nd year in violet buds grouped in large corymbs. They open into small semi-double cups, 3 to 5 cm (1 to 2in) in diameter, in an exceptionally vibrant purple and lilac-pink colour, even in the shade.

'Perennial Blue' is a dynamic, flourishing, and original rosebush, easy to train on a small pole or a column, in a pot on the terrace or even in a small garden, floriferous even in partial shade. It is incomparable for giving a slightly abandoned look planted above too strict flowerbeds. It is an ideal companion for flowering shrubs (bushes, mock oranges, hibiscus) and perennials such as bellflowers and asters, bringing an enchanting charm until late in the season. Trained on an arch close to the terrace will create a colourful passage.

Planting and care

Choose a location with ample sunlight and well-cultivated, nutrient-rich soil. Keep in mind that modern hybrid roses do not tolerate excessive limestone. To prepare the soil, crumble it and place an amendment like blood, fish and bone at the bottom of the planting hole. After planting, water the rose thoroughly to remove any air pockets. Water the plant regularly in the first few weeks to facilitate root development.

Pruning is a crucial step in the flowering process for English roses. At the end of winter, shorten the branches to 3-5 buds above the ground level, selecting an outward-facing bud for a more elegant appearance. Use this opportunity also to remove any dead or unsightly branches. When pruning, cut at an angle above a bud. As the roses bloom, remove any faded flowers to stimulate the growth of other buds.

If you want to plant a climbing rose next to a living tree, be aware that the rose's root system will compete with the established tree roots. Plant the rose in a large container with a perforated bottom at the tree's base to prevent this. The tree's roots will not penetrate the container for at least a year. After a year, you can remove the container by cutting one side without disturbing the rose's root system. This method allows the rose to establish a deep root system, making it more resistant.

Roses may develop unsightly spots at the end of summer, but this is a natural occurrence and doesn't harm the rose's growth.
