Description

Rosa La Bourbonnaise® is a cluster-flowered rose bush distinguished by its vibrant and changing colour palette with early and continuous flowering from May to October, and excellent disease resistance. It is a small, dense bush used in beds, borders, and pots. Its semi-double flowers open wide to reveal a heart of golden stamens, accessible to bees. This Delallier rose is rustic and sophisticated, robust and very hardy.

Created by Delbard and named in 2024, this La Bourbonnaise® 'Delallier' rose is classified in the horticultural group of Floribunda, the "cluster-flowered" roses. It is a modern, repeat flowering bush. The bush has a rounded, dense, and well-branched habit, reaching 60 to 80 cm in height and about 50 cm in spread. Its 5-6 cm diameter flowers, with 15 or 20 petals, have an evolving colour: they change from yellow to orange and then to raspberry pink; a few touches of light green appear as they finish blooming. The very lightly scented corollas open wide to a bunch of golden stamens, visited by pollinators. This flowering renews itself tirelessly from May to October. The deciduous, dark green, and glossy foliage falls in autumn and reappears in spring. Its resistance to rose diseases is considered very good.

This rose was created and selected in Malicorne (Allier) by Georges Delbard Nurseries and Rose Gardens. It has shone in international competitions: in Barcelona 2023, it received the Citizens' Prize and the Senior Council Prize; in Madrid 2024, it won the Gold Medal, First Prize, and the popular distinction "Rosa de Madrid 2024".

Plant this rose in the foreground of a shrub bed and create a trio with other semi-double-flowered floribundas like the pure white Escimo®, the orange-pink Rigo® Apricola, or the bright red La Sevillana®. In front of your roses, plant common lady's mantle or wall bellflowers, for example. These companions create a multicoloured palette from spring to autumn.

Planting and care

Plant your La Bourbonnaise rose in a sunny location (or in light afternoon shade). Modern roses are tolerant, but do not appreciate shallow, poor, and/or very dry soils in summer. They will adapt to any garden provided the ground is well-worked, deep, not too compact, very rich, and always slightly moist. To plant your rose, work your soil by breaking it up well and adding a fertiliser such as dried blood or dehydrated horn to the bottom of the planting hole. Water thoroughly after planting to eliminate air pockets. Water regularly for a few weeks to encourage root establishment.

Roses often become spotted or unsightly by late summer, but this is not a problem for their development. These spots are not harmful to the rose; it is a natural phenomenon.

Care

Pruning instructions Pruning modern repeat-flowering roses is essential for their flowering. It is carried out in three stages: 1. Maintenance pruning: Regularly shorten the shoots that have flowered during the season. To encourage repeat flowering in roses, remove faded flowers along with their stem and 2 or 3 leaves. 2. Autumn pruning: Prune lightly before the true spring pruning. This is not recommended in regions with cold winters as it may weaken the bush. 3. Spring pruning: in February-March, when the buds have become shoots 2 to 3 cm long, prune young strong branches to a quarter of their length. Pruning always aims to open up the centre of the bush and remove dead wood, diseased branches, and weak shoots. Keep the most vigorous ones, usually 3 to 6 well-positioned branches to maintain a beautiful habit. Always prune at a slant, ½ cm or 1 cm above an outward-facing bud.
Pruning Pruning recommended once a year
