Shrubby hydrangeas brighten borders in mid to late summer with their showy, but delicate, long-lasting flowers in shades of pink, white or blue. Many have attractive autumn colour and leaf shape.
Climbing hydrangeas flower in summer and are well suited for covering north and east-facing walls. Most popular is the fully hardy Hydrangea anomala subsp. petiolaris. Evergreen Hydrangea seemannii and Hydrangea serratifolia need shelter as they are prone to cold damage.
