I'm new to perennials and would appreciate any advice. Last year I planted some bear root cuttings, amongst others were hollyhocks,sea holly and erinacea. Each hollyhock sent up a single spike which reached almost 11 ft in height.
Generally if I were to cut back perennials to a shorter height would this encoiurage additional stems being formed.
