Description

Rosa Thierry Marx, named in honour of the famous Michelin-starred chef, combines the charm and fragrance of old-fashioned roses with the floribundity of modern roses. Beyond its ornamental qualities, it is a vigorous variety that is resistant to diseases. Its roses display a truly magnificent colour, with shades ranging from deep pink-violet at the centre to pale lilac-pink at the edges. Their fragrance matches their beauty, and is dominated by citrus notes. This bush rose will be appreciated in the garden for its robustness. Its flowers are sublime in romantic bouquets.

 

Rosa Thierry Marx is a floribunda bush rose launched in 2019 by the rosarian Delbard, belonging to the series of roses 'The Grand Scents'. This slightly stiff bushy and upright shrub reaches an average height of 90cm (35in) with a spread of 60cm (24in) at maturity. It has a rapid growth rate. It produces strong, thorny branches that bear beautiful shiny dark green foliage divided into large toothed leaflets. Throughout summer, the plant produces waves of 8cm (3in) flowers, with an imperfect turbinate shape that is characteristic of the hybrid tea rose category. The double flowers consist of 60 satin petals that evolve from deep pink-violet to very light lilac, creating a beautiful gradient from the centre of the flower to the periphery. Their fragrance is pronounced and rich. It features a discreet background note of undergrowth, a typical rose heart note, and a top note composed of lemongrass, grapefruit, and lemon. The flowers are solitary or grouped in small bouquets, carried at the ends of long shoots from the current year or by those that emerge from 2-year-old stems. The roses will continue to bloom if faded flowers are regularly removed. The foliage is disease-resistant under good growing conditions. 

 

As the rosarian Delbard explains about 'The Grand Scents' roses: "Each of these roses has an intense, very personal fragrance, composed of olfactory notes assembled in an original way. Fleeting or more tenacious, flowery or woody, these notes leave an unforgettable trail like a perfume from a high-end brand".

Rosa Thierry Marx is superb in flower beds, in groups of 3 plants, in large monochrome borders, or in combination with white, pink, or purple roses. It also blends well with light shrubs, perennials, and annuals such as paniculate gypsophila, bellflowers, paniculate phlox, or tall foxgloves. It can be displayed in front of a boxwood or yew hedge, or, conversely, surrounded by a miniature hedge or a carefully organised maze, as in Italian or French gardens. One can also plant a climbing herbaceous clematis with blue flowers like Clematis heracleifolia or a Sollya heterophylla in mild climates at its base. Its roses are stunning in bouquets, paired with lilies and hydrangeas in summer or asters in autumn.

Planting and care

Plant in a sunny or partically-shaded location. English roses are tolerant, but do not like excessive limestone. They will adapt to any garden as long as the soil is well worked, not too heavy, and sufficiently rich. To plant your rose, work the soil by crumbling it and add fertiliser to the bottom of the planting hole (dried blood or dehydrated horn, for example). Water generously after planting to remove any air pockets. Water regularly for a few weeks to facilitate root growth. 

Avoid pruning too short in the first two years.

 

Roses are often stained or unsightly at the end of summer, but this will not hinder their development. These spots are a natural phenomenon and will not harm the rose.

Care

Pruning instructions Avoid pruning too short during the first two years. Pruning is essential for flowering. It is done in three steps: 1. Maintenance pruning: regularly shorten the branches that have flowered during the season. To encourage the reblooming of perpetual roses, remove the faded flowers along with their stem, leaving 2 or 3 leaves. 2. Preparatory pruning in autumn: light pruning that anticipates the proper spring pruning. It is not recommended in regions with cold winters in order to avoid weakening the bush. 3. Spring pruning: in February-March, when the buds have developed into shoots 2 to 3cm (1in) long, trim the young strong branches by a 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 branches, usually 3 to 6 well-positioned ones, will be kept to maintain an attractive habit. Always prune at a slant, ½ cm or 1cm (0.4in) above an outward-facing bud.
