Description
Bud-hardy rebloomer! We wanted a hydrangea with improved bud and stem hardiness in addition to the ability to flower on new wood - and we created Tuff Stuff™ Hydrangea serrata. Deep pink lacecap flowers create a mass of color in early summer, and it continues to produce new flowers right up until frost. The semi-double to double florets begin with creamy coloration in the center before maturing to an intense pink. If you've had inconsistent performance with H. macrophylla, try the Tuff Stuff™ series - they're the reblooming hydrangeas that deliver on their promise.

Soil Moist but well drained soils are best. Mountain hydrangeas are less susceptible to wilting than bigleaf hydrangeas, but cannot take soggy conditions for any period of time. Tolerant of a range of soil pH levels, however, soil pH will influence flower color.

Pruning Avoid pruning mountain hydrangeas, except to remove any dead wood. These hydrangeas cannot be cut back or trimmed at any time of the year without impacting the bloom for either the current season or the next. Though they do rebloom readily on new wood, the best display comes from treating them as though they bloom only old wood.

Uses Mountain hydrangeas can be used the same as bigleaf hydrangeas: perfect for flower gardens, cottage gardens, and seaside plantings. They also make a showy addition to foundation plantings and can be used for low hedges or edging.

Growing Tips Mountain hydrangeas are from the same area of Japan as bigleaf hydrangeas but grow in the mountains instead of the seaside. As a result, they have naturally developed better cold tolerance and thus make an outstanding choice for gardens in USDA zones 5 and 6 especially.
