PIMPRENELLE™ – yellow groundcover rose – Delbard
If You dream of a neat, low, flower-filled edge that simply gets on with the job, PIMPRENELLE™ is an easy-going groundcover rose made for Irish family gardens. Its naturally bushy habit forms a dense, gently arching carpet of mid-green foliage, quickly covering bare soil so You spend less time weeding and more time enjoying the display. Clusters of medium-sized, semi-double blooms open a cheerful yellow then soften through buttery tones to a light ivory, keeping the bed bright for long stretches of the season. Because the petals drop away cleanly, the plant stays fresh-looking without regular deadheading, ideal if You prefer simple routines. As an own-root shrub, it settles in steadily, building strong roots in year one, fuller shoots in year two and its best ornamental show by year three, giving long-term confidence without complicated care. It suits typical Irish conditions, coping well where soils are heavy and need thoughtful drainage, and works just as happily in a generous container or a sunny front border by Your door.
Use cases

The semi-double, medium flowers and mid-green foliage blend easily with perennials and herbs, bringing cottage-garden charm without needing staking or complex pruning, ideal for relaxed-design garden enthusiasts |
