Compact, bud-hardy reblooming hydrangea. Tiny Tuff Stuff™ hydrangea is extremely cold tolerant and beautiful. Extremely bud-hardy, each year it produces abundant lacecap flowers comprised of doubled sepals which appear on both old and new wood. The flowers age to an attractive pink, and tip down in a distinctive arching fashion. It has smaller, narrower leaves and an abundance of dainty flowers that cover the plant every summer.

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.
