Pruning the shrub rose Rosa glauca

Shrub roses generally have minimal pruning, usually confined to the removal of old, unproductive shoots at the base at the commencement of growth in spring. There are different systems for different shrub roses, early flowering types that flower on wood made the previous season are usually pruned immediately after flowering. 

Pruning is about getting what you want from the plant rather than following the dictates of text books (and people like me!). There will always be exceptions to the 'rules' and one such exception can be Rosa glauca. Rosa glauca is a plant indigenous to southern Europe and has distinctive coppery grey foliage and small pink flowers followed by red fruits. The stems are mercifully devoid of spiteful thorns. It is also known by its synonym Rosa rubrifolia. 

The best foliage is obtained by hard pruning in spring, I know one head gardener of one famous garden in England who pruned his specimens to ground level every March. This will create vigorous growth at the expense of flowering. Flowers will appear on hard pruned specimens but will be be fewer in number and appear later than plants that have been pruned more lightly. The choice is yours. 

Rosa glauca- prune it to achieve the effect you want
