Kordiam hybrid tea rose – KORdiam
With its upright, bushy habit and refined, cut-rose style blooms, Kordiam is an easy, reliable choice if You want a smart, elegant rose that simply settles in and performs. Large, high‑centred flowers in a soft coral‑orange to pastel pink‑peach range bring a romantic but tidy look to front gardens and smaller borders, working beautifully beside cottage‑style planting without becoming unruly. As an own‑root plant it builds strength gradually, supporting a naturally long life and steady flowering that suits busy households and typical Irish conditions with their cool summers and humid air. In year one it concentrates on rooting, year two brings fuller shoots and more buds, and by year three You can enjoy its mature ornamental effect with minimal extra effort. Good disease resistance and low routine care keep it manageable even where time is short, while its medium height makes it versatile for beds, edging or a feature near the door. Container‑grown in the pharmaROSA® ORIGINAL 2‑litre pot, it arrives well‑rooted and ready to plant so You can simply water, feed, and watch it develop into a lasting part of your garden picture.
