Description

The Bushy Cluster-flowered Rose Utopia is first remarkable for its very bushy appearance and strong growth. Then for the abundance of its endless flowering, which begins in June and only ends with the first frost. These are hundreds of bouquets of small flowers, cream-coloured with a slight pink hue that becomes pastel pink, which overwhelm the dark green and dense foliage of this astonishing disease-resistant polyantha. An excellent variety, holder of the highly demanding German ADR label*, full of charm and suitable for all styles of gardens. Definitely worth discovering!

The Utopia Rose 'Delsimros' is a Delbard creation dating back to 2012, awarded with 7 medals. This polyantha rose quickly forms a rounded, flexible, well-branched bush at the base, with thorny stems, about 90 cm (35in) in all directions, and covered with deciduous foliage that is very healthy, cut into leaflets of a shiny dark green. Its flowering is particularly recurrent and abundant from June to October-November if faded flowers are removed. Its small corollas are semi-double, flat, very tight, and gathered in bouquets of 10 to 15 flowers. The tightly closed rose-colored flower buds open in cream-pink, then bloom into round and well-opened cups, pastel pink around a golden stamen centre.

*This rose is particularly resistant to diseases. It has obtained the highly selective ADR label, awarded to vigorous and floriferous roses that are resistant to diseases, cold, and parasites. These roses have been evaluated for 3 years in 11 rose gardens in Germany, located in various different climatic zones where no treatments are carried out. This label is a guarantee of high quality and hardiness. 

Cluster-flowered roses allow for the creation of beautiful small hedges, planted in mixtures in small shrub beds or in front of larger shrub screens. Combine them with abelias, nandinas, or caryopteris for example. They are good companions for peonies, Nepetas, paniculate phlox, and tall baby's breath. The vigor of 'Utopia', its charm that invariably appeals to rose lovers, makes it an interesting variety for all gardens. Its cultivation is within everyone's reach. Its uses are multiple, according to each gardener's desires: in a rose bed, in the company of white varieties ('Marie Pavie', 'Swanny'), or mauve ('Blue Boy', 'Rhapsody in Blue', 'Roman Waltz'), or red, or mixed with easy-to-grow perennials such as perennial geraniums, small-flowered carnations, or blue asters. And its pastel and light roses are absolutely adorable in bouquets!

Planting and care

Plant the 'Utopia' rose from November to March, in ordinary, well-tilled, well-prepared, and well-drained soil. Polyantha roses prefer clayey soils, rather heavy than light, and fertile. In soil that is too sandy, too compact, or too dry in summer, it is advisable to incorporate compost, decomposed manure, or leafmould at the bottom of the planting hole. However, this rose fears waterlogged soil in winter. Place it in a sunny position, or at most in partial shade. Roses are hungry plants, so a specific fertiliser will be beneficial at the start of the vegetation season, and regularly throughout the flowering period. To encourage reblooming, regularly remove faded flowers. Polyantha rose varieties are more vigorous and floriferous than large-flowered rose varieties. Therefore, cut the stems by about one quarter of their length (from 4 to 6 buds from the base of the stem) at the end of winter. Always prune above an outward-facing bud to encourage bushiness and prevent branches from intertwining in the centre of the canopy.
