These are reblooming lace-cap hydrangeas called mountain hydrangeas, which originally grew in mountain valleys in Japan, China, and Korea. Tuff Stuff Hydrangeas look similar to big leaf hydrangeas but are more tolerant of less-than-perfect growing conditions. Tuff Stuff Hydrangea is sometimes referred to as Cotton Candy Hydrangea or Blueberry Cheesecake Hydrangea.

Tuff Stuff Hydrangeas grow to be 2-3 feet tall and 2-3 feet wide. There is even a miniature version called “Tiny Tuff Stuff” that only grows to 18″-24″ tall and wide. The flowers bloom in the late spring and early summer, and the blooms last until fall or when things start to frost over. These hydrangeas bloom once every year.

The Tuff Stuff Hydrangea blooms can be found in pink, purple, and blue. You can change the color of the blooms by changing the acidity or alkaline level of the soil that your hydrangeas are planted in. You can even change the color of the blooms every year before the spring season begins. If the soil is acidic, the blooms will be purple or blue. if the soil is alkaline, then the blooms on your Tuff Stuff Hydrangea will be pink in color.

Planting & Soil Requirements For Tuff Stuff Hydrangea

Make sure you don’t plant them when it is really hot, wait until the temperature starts to cool down so your Tuff Stuff Hydrangeas don’t get heat stress, as they will struggle to grow if they get heat stress.

After you plant your Tuff Stuff Hydrangeas, cover the topsoil in a 2-3 inch layer of mulch that is shredded. This will prevent moisture in the soil from escaping and ensure that the soil stays moist for a long time, which will allow your Tuff Stuff Hydrangeas to grow and thrive.

“An adaptable garden plant, it is compact and tidy enough to thrive in a decent-sized container while also holding its own near the front of an herbaceous or shrub border. It only really needs pruning when there is old wood to be thinned out and in temperate areas it will grow happily in both partial shade and full sun, but it will be grateful for afternoon shade in a really warm climate.”
