Rosa glauca is an exceptionally beautiful rose, bearing small clusters of single, pink flowers with pale pink centres in summer, followed by round, red hips in autumn. Its a vigorous, arching species ? perfect for growing at the back of a border or training as an informal flowering hedge. Its bluish-grey leaves and ornamental rose hips are excellent in flower arranging.
This rose is one of the only species worth growing from seed, all aspects being desirable. Thornless, purple-red stems of attractive grey leaves, and pale-centred, cerise pink flowers age to bunches of dark red hips. Superb as a bush, but magnificent as a standard.

Sowing advice: these seeds have already been thoroughly cleaned and cold-stored for several months. They should be sown into well-drained, sandy compost at any time of the year, and covered to their own depth with sand or grit. No artificial heat is needed; the seed tray is best left in a cool spot outside and kept moist. Seeds germinate very slowly indeed in the spring after a chilling in the cold compost, regardless of when they are sown. Some seeds may take more than a year to germinate.
When seedlings are large enough to handle transplant into 7.5cm (3in) pots and later into 13cm (5in) pots and overwinter in a frost free greenhouse or coldframe. The following spring gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost 5cm (2in) deep and 38-45cm (15-18in) apart in a sunny spot on fertile well drained soil.
