Maintenance Notes: 

Prefers moist, well-drained soils. Soil will affect bloom color. In acidic soils with good aluminum availability the flowers will be blue. They will turn lavender-pink in more acidic soils. Pruning is generally not needed, but the plant may be shaped immediately after the first bloom of the season.

Very hardy reblooming hydrangea!  We love Hydrangea serrata because they are so bud hardy and bloom reliably.

This is a real beauty, with flowers so delicate and refined that it seems strange to call them tough - but they are. As mentioned, extremely bud-hardy, each year it produces abundant lacecap flowers comprised of doubled sepals. It is a rebloomer. While this plant leans to blue, the flower color may range from blue to pink to white, all soft, delicate shades perfect for refined gardens.

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. It has never failed to bloom in our western Michigan trial gardens. Add aluminum sulfate to the soil to encourage blue flower color.

  • We planted three of these in our zone 6 yard last summer, because they claimed to be cold hardy and our big-leaf hydrangeas were having trouble. This spring two of the Tiny Tuff Stuffs had died to the ground, and the third had died all together. It was an unusual winter, with a warm February and cold March, but we were very disappointed. The regular big leafs died to the ground too, but seem to be coming back more vigorously.

    Marginally Adequate Performed below expectations but may be willing to try again.
