KAREN BLIXEN ™ – white tea-hybrid rose - Olesen & Olesen
Imagine a quiet step outside after summer rain, soft light catching the pure white blooms of KAREN BLIXEN ™ as they gleam against glossy dark foliage, bringing a sense of gentle calm to a small Irish garden. This upright, bushy hybrid tea offers large, classic, high‑centred flowers on a compact plant that fits comfortably into cottage borders or neat Dublin front beds, even where space is limited and the outlook is softened by frequent rain and moist, heavy soil that simply needs sensible drainage for healthy roots. As an own‑root plant it promises long‑term stability, quietly rebuilding if ever cut back hard and keeping its shape without complicated pruning, so you can enjoy reliable, repeat flowering over the season rather than battling demanding maintenance. In its first year it concentrates on roots, in the second it gains confident height, and by the third it reveals its full ornamental presence, rewarding patient, relaxed gardeners who want beauty without fuss.

High‑centred, pointed buds on long, straight stems are perfect for vases, with pure white petals that hold colour well indoors, so one small planting can supply elegant blooms throughout summer for the home flower arranger. |
| Sunny, well‑drained clay border |
Thriving best in full sun with decent drainage, it fits Irish clay gardens where you can improve the top 30–40 cm with compost and grit, avoiding waterlogging yet coping well with our soft, rain‑cooled summers for the practical garden owner. |

The mild, white‑rosy scent is best appreciated close by, so planting near a bench or patio lets you enjoy both the fragrance and luminous blooms during quiet evening moments outdoors for the fragrance‑appreciating buyer. |
