ALDEN BIESEN – light pink park rose – Lens
Professional propagation of ALDEN BIESEN as own-root material gives growers a reliable park-shrub option for borders, hedging and public plantings where low-intervention management is valued, while its dense foliage, upright habit and repeat flowering support visually coherent plantings in thematic rose gardens and collection displays. With strong disease resistance and RHS H7 hardiness, it adapts well across UK nursery networks, offering dependable structure in open-ground beds or 2–3 litre container production for standard finished stock. The pharmaROSA NEONATAL format integrates cleanly into professional logistics, with tray-rooted cuttings at a uniform stage helping you plan transplanting, hardening and onward cropping with predictable time-frames. Own-root plants underpin long-term, renewable stands with reduced replacement need and stable identity, supporting sustainable stock blocks and private-label ranges even under repeated cutting or renovation, while the development from root establishment through framework build to full ornamental effect over three seasons remains clear and manageable. This is particularly useful where institutional and landscape clients expect durable, low-input plantings that withstand colder, wind-exposed sites, ensuring homogeneous batches for wholesale and resale into landscape and retail channels. With compact, bush-trained growth and a generous second flush, ALDEN BIESEN is straightforward to finish in standard containers yet has the stature to scale into larger landscape formats, offering versatile scheduling options for project-based production and continuous programme supply. For nurseries building a broad, own-root shrub rose range to cover park and collection purposes, the combination of dependable garden performance, easy routing into standard 2–3 litre lines, and robust technical parameters makes this cultivar a practical, low-risk component of a full-market assortment.

| Flower morphology |
Small, flat, single to semi-double clusters with around 5–12 petals, repeat-flowering with a generous second bloom; weakly self-cleaning, so spent clusters may need deadheading. |

| Fragrance and aroma |
The variety is effectively unscented, with no noticeable fragrance recorded; flowers offer limited pollinator appeal owing to their small, more double structure and reduced stamen accessibility. |
