DELROSAR – pale pink climbing rose - Delbard
Step out after rain and be greeted by a curtain of fragrance and soft, pale-pink blooms: DELROSAR brings a romantic, vertical accent to small London front gardens while coping well with cool, damp spells and brisk coastal winds. This large-flowered climber offers season-long colour with very full, self-cleaning blossoms that keep the display tidy with minimal effort. Its dense, dark green foliage clothes arches, fences and porch pillars, giving reliable structure through many years thanks to the inherent longevity of an own-root plant that can quietly regenerate from the base. Planted once with decent drainage and a sturdy support, it matures from establishing roots, to strong shoots, to full ornamental presence over three seasons, rewarding patient, low-fuss gardeners. For a contained footprint, it can even be trained in a 40–50 litre pot for a softly scented vertical feature.
