Description

The Kadora Standard Rose is a variety of with clustered flowers that combines many qualities. Its flowering, with its vibrant red colour, is particularly long and abundant. It offers exceptional resistance to diseases, which has earned it the German ADR label, and its beautiful foliage remains evergreen in mild climates. It requires little maintenance. Give it a special place in the garden or even in a large pot on the patio, and it will be a stunning decoration for many years.

 

Standard roses are obtained by grafting a variety (in this case, the Decorosier Kadora rose) onto a single, upright stem from a different rose (Rosa canina, R. laxa or R. multiflora). The graft is performed at the top of the stem. In very cold regions, it may be necessary to protect the rootstock during winter.

The Decorosier KADORA Standard Rose was launched in 2006 by Guillot. This variety belongs to the floribunda and polyantha rose family, which produce flowers grouped in clusters. Grafted onto a stem, it has a characteristic habit, with a slender, vertical 'trunk' bearing a large, rounded crown. Its thorny stems carry abundant, glossy foliage, divided into small, tough, and serrated leaflets of dark green colour. It blooms abundantly from May to June until October to November, if regularly pruned and provided with enough water. The semi-double flowers are gathered in clusters of about ten units and are 4 to 6 cm (2in) wide. The tight buds open into open cups, revealing a small heart of yellow stamens. This rose has no fragrance. The plant retains its leaves during winter if the weather is not too harsh.

DECOROSIERS are shrub roses with a spreading habit. They can be used in various ways, such as edging lawns, in flower beds, on slopes, or in planters. They adapt to all types of soil, in sunny or semi-shaded locations. They offer long and exceptional flowering on healthy, glossy, semi-evergreen foliage. Naturally resistant to diseases, they do not require any treatment.

ADR is the label of the German Federation of Rose Breeders. The ADR designation is only given to varieties that have passed the strictest tests worldwide. The plants are tested simultaneously at 10 different locations, under various soil and climate conditions, for several years. The tests evaluate hardiness, perennial character, and flowering without the use of any pesticides.

 

This Kadora Standard Rose is a magnificent specimen, to be placed in the centre of a bed of delicate perennials, along a pathway, near the patio, in a well-maintained small garden, or in a large pot on the balcony. Its red colour stands out from afar in the garden and pairs well with white, orange, blue, or yellow flowers. For example, you can plant nepetas, chamomiles, perennial salvias, foxgloves, nigellas, or tall gypsophila alongside it. A groundcover composed of silver basket or lady's mantle will highlight it perfectly.

Planting and care

Plant the 'Kadora' Syandard Rose from November to March, in ordinary, well-tilled, and well-drained soil. Roses prefer clay soils, rather heavy than light. In soil that is too sandy, too compact, or too dry in summer, it is preferable to incorporate compost, decomposed manure, or humus at the bottom of the planting hole. However, this rose dislikes waterlogged soils in winter. Place it in a sunny location, or at most in partial shade. Roses are demanding plants, so a specific fertiliser application will be beneficial at the start of the growing season, and regularly throughout the flowering period. To encourage reblooming, regularly remove faded flowers. Floribunda rose varieties are more vigorous and more floriferous than large-flowered rose varieties. Therefore, prune the stems to about a quarter of their length (from 4 to 6 buds from the base of the stem) at the end of winter. Always prune above an outward-facing bud to encourage bushiness and prevent branches from becoming tangled in the centre of the branches.

In regions with very cold winters, it is advisable to protect the grafting stock of stem roses (the 'trunk') by wrapping it in a thick winter fleece.
