A new color for the Tuff Stuff series! The improved bud and stem hardiness, the reblooming habit, and the double lacecap flowers of the original - but Tuff Stuff Red brings with it dark red-pink flowers. Flowers open to a two-toned green and red, maturing to all red. Strong stems give this mounded hydrangea a handsome presentation both in the container and in the landscape. Developed by Tim Wood at Spring Meadow Nursery.

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.


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.


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.
