Diamant® bedding floribunda rose – KOReb

Diamant® is an easy, reliable floribunda that fits beautifully into Irish family gardens, giving clusters of glowing orange blooms without complicated care. Its compact, upright habit keeps beds neat and manageable, while the flowers repeat generously for a long season of colour. Bred by Kordes with naturally healthy foliage, it is well suited to our damp, mild climate and the challenges of persistent humidity and fungal pressure. The vermilion‑orange buds open to full, double, cup‑shaped flowers that fade gently through warm peach tones, bringing a soft cottage‑garden charm to front gardens and smaller borders. On its own roots, this rose knits into the soil, building a stable bush that ages gracefully and regenerates reliably after pruning. With a planting arc where year one focuses on roots, year two on stronger shoots and year three on full ornamental impact, You can simply plant, water, and enjoy its dependable performance for many years with only light routine care.

Use cases

Target area Reason
Front garden flower bed along a path or driveway Compact, upright growth and 60–85 cm spread make Diamant® ideal for tidy, low flower beds that do not overwhelm small front gardens, while its bright orange clusters give strong kerb appeal with minimal upkeep for busy homeowners
Small group planting of 3–5 roses in a family garden Planting in small groups creates a rounded, continuous block of colour; its remontant flowering ensures repeated flushes, so even a modest planting looks abundant, rewarding those who want visible results from little gardening experience for beginner gardeners
Mixed border with perennials and grasses The mid‑green, slightly glossy foliage and stable, own‑root structure allow Diamant® to blend well with grasses and perennials, gradually forming a balanced shrub that anchors the border visually over many seasons for long‑term planners
Cottage-style bed with soft, romantic tones The colour journey from vibrant salmon‑orange to warm peach and light cream at the petal tips gives gentle, shifting tones that pair beautifully with pastel companions, creating a relaxed, romantic cottage feel with little maintenance for romantic gardeners
Low hedge or edging line around a lawn or patio Recommended spacing of about 40–50 cm lets You create a neat, low hedge that defines paths and lawns; its moderate height and upright habit keep sight lines open while providing a long season of colour for family spaces
Cutting corner for simple home bouquets Large, very double, cup‑shaped flowers with over 40 petals and a mild, sweet scent make Diamant® attractive for informal indoor arrangements, letting You cut stems through the season without noticeably thinning the display outdoors for home decorators
Coastal or exposed Irish sites with damp conditions Robust, disease‑resistant foliage and reliable hardiness help this variety cope where wind and damp increase fungal pressure, supporting healthy growth in gardens that often stay wet and cool in our Atlantic climate for coastal gardeners
Large container on a balcony, terrace, or paved area Planted in a 40–50 litre container with good drainage, Diamant® keeps a manageable size yet flowers generously, bringing strong colour to paved or balcony spaces where soil is limited and care needs to stay simple for urban gardeners

Decorating ideas

  • COTTAGE RIBBON – Plant a soft ribbon of Diamant® along a low fence, underplanting with aubrieta and rock cress for spring colour that melts into summer rose blooms – ideal for lovers of traditional cottage‑style gardens
  • WARM WELCOME – Flank your front door with two large containers of Diamant® and trailing blue sedge, giving a warm orange‑and‑blue contrast that stays neat and easy to look after – perfect for busy homeowners wanting instant kerb appeal
  • FAMILY BORDER – Mix Diamant® with lavender and dwarf rosemary in a sunny border so the roses provide height and colour while the herbs add scent and structure – great for families who like a low‑maintenance, sensory garden
  • ORANGE HEDGELET – Use a single line of Diamant® at 40–50 cm spacing to edge a lawn or patio, clipping only lightly each winter – suited to those who want clear garden structure without complicated pruning
  • PEACH GLOW – Combine Diamant® with white hydrangeas and silver foliage plants so its orange‑to‑peach blooms glow against calm, pale companions – attractive for gardeners aiming for a soft, romantic summer display

Technical cultivar profile
Property Data
Name and registration Diamant® bedding floribunda rose, registered as KOReb, ARS exhibition name Diamant; floribunda bed rose type bred for clusters of showy blooms suitable for both garden display and cutting.
Origin and breeding Bred by Reimer Kordes at W. Kordes’ Söhne, Germany, from a cross of ‘Korona’ × ‘Spartan’; introduced and registered in 1962, originally distributed by Jackson & Perkins in the USA.
Growth and structure Upright floribunda with moderately dense, mid‑green, slightly glossy foliage; grows to about 80–105 cm high and 60–85 cm wide, forming a bushy, well‑filled bedding rose with moderate prickliness.
Flower morphology Large, very double, cup‑shaped flowers with over 40 petals, borne in clusters; flower size typically in the 2.75–3.95 inch range, with strong repeat flowering and a notably abundant second flush in season.
Colour and phenology Closed buds deep vermilion‑orange; freshly opened blooms vibrant salmon‑orange; ageing through warm orange to peach‑orange with light cream at the tips, maintaining overall colour well before finally fading.
Fragrance and aroma Soft, sweet fragrance of mild strength, noticeable at close range without being overpowering; primarily grown for colour and form rather than perfume, yet adding a gentle scented element near paths and seating.
Rose hip characteristics Occasional ellipsoid red hips, around 8–12 mm in diameter, forming sporadically if spent flowers are left on the plant; mainly of incidental ornamental value rather than a dominant decorative feature.
Resistance and hardiness Good overall disease resistance with recorded resistance to powdery mildew, black spot and rust; hardy to about −21 to −18 °C (RHS H7, USDA 6b, Swedish Zone 3), reliable in most Irish garden conditions.
Horticultural recommendations Prefers a sunny position and fertile, well‑drained soil; suited to beds, borders, low hedging and cutting. Space 40–50 cm apart depending on effect; maintain with regular watering, feeding and light annual pruning.

Diamant® offers reliable orange colour, compact structure and strong disease resistance on a long‑lived own‑root plant that settles steadily into your garden, so You can plant with confidence and decide in your own time.

Fragrance and Aroma

Information about the videos
The video series is not a “seasonal showcase”, but makes the essence of pharmaROSA® own-root production tangible: how the plant is built, what the root system is like and how the shoots renew themselves. The footage was therefore taken at different times, showing plants at different stages of development, so mixed leaf coverage or differing growth stages may appear in the videos. This is not a “sample” of the batch delivered, but an illustration of how the technology works. The current condition of the rose available to order — typical of the given period and similar to what you can expect to receive in the parcel — is shown at the top of the product page.
