Rosa glauca aka Red Leaved Rose

Rosa glauca, or redleaf rose, belongs to the rose family. It comes from mountain regions in central and southern Europe. Gardeners grow this species chiefly for its purple-toned leaves. Their waxy surface blends shades of plum, gray, and green. The plant also bears pink flowers and bright red hips. It attracts birds and butterflies to the garden.

This deciduous shrub grows fast and sends up suckers. Its arching branches form a broad, vase-shaped plant. Garden plants reach about 5–8 feet (1.5–2.44 metres) tall. They spread about 7 feet (2.13 metres), sometimes wider. Branches arise from the base and bear reddish-purple canes. Sources differ on prickles, describing sparse thorns or stems covered in curved prickles. The alternate leaves are pinnate, with five to seven leaflets. Each leaflet has an oval shape and toothed edges. Autumn leaf color adds little to its display.

The flowers open in May and June. Each pink bloom has five petals and a light scent. Flowers measure about 1–1.5 inches across. Orange-red hips follow and ripen in autumn. These small, oval fruits may remain well into winter. Some bear small bristles on their surface. The hips and colored canes add interest after leaf fall. Plant it alone, in small groups, or as a hedge. It also suits shrub borders and the back of perennial beds. Open woodland and shade gardens offer other possible settings.

Give this rose rich, well-drained loam with moderate moisture. It tolerates a range of soil pH levels. Full sun supports strong flowering and helps limit disease. Partial shade may bring out the best leaf color. Chicago Botanic Garden lists USDA hardiness zones 2–8. Water deeply and regularly, and avoid wetting the leaves. Mulch helps hold moisture and keeps roots cool. Allow air to move through the branches. Prune as needed in late winter and remove fallen diseased leaves. Leaf diseases are a known problem with this species.

The hips are edible raw or cooked, but contain little flesh. Their tough skin surrounds many seeds. Remove the hairs around the seeds before eating the fruit. These hairs can irritate the mouth and digestive tract. Cleaned seeds can be ground and added to flour or food. Plants For A Future gives its edible value two out of five.
