Perennial Blue is a fast-growing rambling rose from 2003 bred by Bernard F. Mehring in his company Eurosa in England, and now is offered by Rosen Tantau. It is a cross between Super Excelsa and Veilchenblau. It makes rich clusters composed of small, 3-4 cm across, semi-double flowers of a unique colour: a blend of deep pink, mauve, and magenta. The centre is decorated with a small white eye around yellow stamens. Flowering time is from mid June to early July with two more weaker flushes in August and September. Deciduous leaves are small, medium green, partially glossy, and stems are almost spineless.

Planting instructions: Prepare a hole of size 30x30 cm. Put your rose in the way that the grafting point is 3 cm deep in the soil. Water well and cover new shoots with soil or bark mulch about 15 cm high. Roses tolerate wide range of soils but thrive in deep, humus-rich, moist but well-drained soil, in full sun.

Pruning: rambling or climbing roses are not supposed to be pruned. Just remove old or ill branches. Deadheading will help setting new flower buds.
