Description

Rosa Alexandra David Neel® Deldentros, from the "The Great Perfumes" collection by Georges Delbard, pays tribute to the famous explorer of the same name who was also a passionate rose lover. This variety is distinguished by its large double and toothed, pink-purple, highly fragrant flowers from May until the first frost. Disease-resistant and very hardy, it has won several prestigious awards, notably in Rœulx, Belgium, and Baden-Baden, Germany.

Created in 2020 by Georges Delbard, Rosa Alexandra David Neel® Deldentros belongs to the group of cluster-flowered bush roses or floribundas, with flowers grouped in clusters. This vigorous and upright shrub measures between 60 and 80 cm in height, with an elegant habit and beautiful shiny dark green foliage. Its 9 cm diameter flowers have over 60 toothed petals, in a lovely pink-purple to mauve-pink hue. The flowering is perpetual, starting in May-June and lasting until the first frost. The deciduous foliage is absent in winter.

The powerful fragrance of the flowers, with intense floral notes, will delight enthusiasts of scented roses. Added to all these qualities are excellent disease resistance and great hardiness, down to -20°C. Exceptional qualities that have been recognised in several international competitions: it notably received a Certificate of Merit in Rœulx in 2020, as well as a medal in Baden-Baden in 2021 and in the Grand Duchy of Luxembourg.

Rosa Alexandra David Neel® shines in sunny beds, bringing a fantastic charm. To create a harmonious atmosphere, it is best to associate it with soft tones, such as pink, mauve, blue, and white, to enhance its delicacy. Choose for example Japanese Anemone 'Honorine Jobert', with delicate white flowers, Nepeta 'Walker's Low', covered in lavender-blue spikes, Astrantia major 'Roma', with pale pink flowers, and Echinacea 'Mini Belle' for its bright pink pompom flowers. All these perennials will enhance the subtle nuances of the rose while adding volume and texture to the whole.

Planting and care

Plant your Rose Bush Alexandra David Neel in a sunny location or in light shade. Modern bushes are fairly tolerant, but do not appreciate excess chalk. They will adapt to any garden as long as the soil is well worked, not too heavy, and rich. To plant your rose bush, work the soil well by crumbling it and placing a base fertiliser at the bottom of the planting hole, such as dried blood or dehydrated horn. Water generously after planting to remove air pockets. Water regularly for a few weeks to facilitate rooting. Avoid pruning too short during the first two years.

Pruning modern perpetual roses is essential for flowering. It is done in three stages:

1. Maintenance pruning: regularly shorten the flowering shoots during the season. To promote the reblooming of perpetual roses, remove faded flowers along with their stem with 2 or 3 leaves.

2. Autumn preparatory pruning : This light pruning anticipates the true spring pruning. 
In regions with cold winters, it is not recommended as it may weaken the bush.

3. Spring pruning : in February-March, when the buds have become shoots 2 to 3 cm long: prune the young strong branches to one quarter of their length.

Pruning always aims to clear the heart of the bush and remove dead wood, diseased branches, and weak shoots. The most vigorous ones will be kept, usually 3 to 6 well-positioned branches to maintain a beautiful habit. Always prune at an angle ½ cm or 1 cm above an outward facing bud.

In regions with cold winters, it is not recommended as it may weaken the bush. 3. Spring pruning: in February-March, when the buds have turned into shoots 2 to 3 cm long: trim the young strong branches to a quarter of their length.

Keep the most vigorous ones, usually 3 to 6 well-positioned branches for a beautiful habit. Always prune at an angle ½ cm or 1 cm above a bud facing outwards.
