Product Details

Product Details

As its name promises, this new Mountain Hydrangea is very hardy and reblooms consistently on new wood until frost. The large, reddish pink or purple-blue florets have a contrasting greenish white eye, with burgundy fall foliage completing the season-long color show. A Proven Winners®/Color Choice® variety. ‘MAK20’ PP 24,820

For this Hydrangea, you can change the color of your blooms by using one of our soil additives, flowers will generally be more blue when grown in acid soils, and pink when grown in alkaline soils.

Hydrangea is a valuable genus of some 100 species of shrubs and vines grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall—a quiet time for most woody plants—and are worth having for that reason alone.

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.

Love these little shade hydrangeas

I have purchased 9 of these small little shade hydrangeas over 3 years, and they have all bloomed and look beautiful every year. They are planted along with hostas under different kinds of shade trees, and I look forward to their pretty pink blooms every year. They add color to my shady places where once there was only green. They have returned reliably every year.

Contact number below.

Eileen there is an 800 number at the very bottom of this page in the white area. It is difficult to see. I hope your plants had a "resurrection." I think I am going to try Let's Dance-Starliight instead of the Tuff Stuff.

Tuff Stuff is not so tuff

In March 2016 I paid for two hydrangea serrata Tuff Stuff #63215. The plants arrived in boxes. Each plant had one leaf, and the instructions to plant as soon as possible. I planted them in two different locations, both suitable to hydrangea. One lost the only leaf it had and has shown no sign of life since, although today is June 22, 2016. The other one now has four leaves. I can't find a customer service email address on this website, and since this is my first purchase from White Flower Farm, I don't have an account. Mail order companies need to provide easy access to support staff when a plant doesn't meet expectations. I don't know if the roots of these hydrangeas were frozen during shipping or damaged in packing, but I do know that they were a waste of money.

Beautiful flowers, wish they lasted!

I purchased this hydrangea last spring. The first year it didn't really bloom, but the second year we saw beautiful blooms in July. They quickly faded however and browned. They are in a part sun area of our garden. I am crossing my fingers that the blooms last longer next year! If not, I might move it.

Didn't survive the first year

Unfortunately this plant, along with several others I ordered from White Flower Farm, did not survive the first year. I was really looking forward to this beautiful plant. It looks gorgeous in the pictures. I have 3 other hydrangeas that are already full of leaves, so I don't think it's just too early in the season.

Growing H. serrata

Light/Watering: Most varieties thrive in full sun in the North, but in the South require afternoon shade. Moist soils that do not dry out are best; do not plant in hot, dry, exposed sites. Mulch to conserve moisture and buffer soil temperatures.

Fertilizer/Soil and pH: In some varieties, flower color is determined by the pH of the soil; at low pH (acid soils) flowers will be blue and at higher pH, flowers will be pink. Generally, a pH below 5.0 results in deep, vivid blues and as the pH rises the flowers range from blue to lavender to mauve to a vivid deep pink at pH 7.0 (neutral). The pH determines the availability of aluminum in the soil; this element is more readily available in acid soils, and this availability results in the blue flower color. Since phosphorus ties up aluminum in soils, using a fertilizer low in this nutrient will aid in attaining blue flowers. If pink flowers are desired and your soil is acid, simply add lime to raise the pH and use a balanced fertilizer. Aluminum sulfate will lower pH if blue flowers are desired.

How to test your soil?

We recommend that you visit your local Cooperative Extension Service to find out about soil testing in your area. Follow this link for a directory of institutions involved in the Cooperative Extension program.

Pests/Diseases: None serious. Occasionally powdery mildew will infect the foliage, especially in humid areas with poor air circulation. Treat with an appropriate fungicide if the problem is serious, and be sure to rake up and destroy all fallen foliage in the autumn.

Pruning: Little pruning is needed, but if shrubs grow too large, cut back stems by about one-third by the end of August. In spring, only prune out dead wood. Most Hydrangea serrata varieties bloom on old wood. H. s. Tuff Stuff™ is a variety that blooms on both old and new wood. If no fall pruning was done, stems can be cut back by one-third in spring if necessary—but this will sacrifice the bloom on the old wood and shrubs will not flower until late summer.

Transplanting: Young plants may be transplanted when dormant in early spring; larger tree-form varieties are difficult to move once established, but it can be done. Prune top growth after transplanting to reduce water loss.

End of Season Care: Rake up and destroy any fallen foliage that was infected by powdery mildew or other fungi.

Calendar of Care

Early Spring: Prune out any dead wood from all varieties. Check soil pH and adjust up or down if needed for desired flower color. Feed plants with a fertilizer high in phosphorus (such as 15-30-15) to encourage blooms. Complete any transplanting before leaves unfurl.

Mid-Spring: Mulch plants after soil has warmed to conserve moisture and buffer soil temperatures. Watch for powdery mildew and treat as needed.

Summer: As soon as blooms fade, remove old flowering stems. If needed, prune as indicated above by the end of August.

Fall: Remove and destroy any fallen foliage that was infected by powdery mildew. If not pruned in spring, plants can be shortened, or pruned back to the ground.
