Cold-hardy Hydrangea is a reliable bloomer.
PeeGee Hydrangea, trained to a large, single trunk for quick, upright growth. This plant is well-loved by generations of gardeners and for good reason: in August and September it produces huge conical trusses of double flowers--up to 18in long--that are rich creamy white and fade gradually to shades of pink and then brown.
The foliage is a dark green that shows off the flowers to good effect. On its own it makes a broad shrub to 12ft high and 10-15ft wide. Some gardeners prune it up to create a small tree. It flowers on new growth and so can be pruned in spring to make a smaller plant; this also produces the largest flowers. PeeGee Hydrangea is one of the best varieties for cutting and for drying.
