Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionTuff Stuff™ mountain hydrangea (Hydrangea serrata) is truly an exceptional plant – in fact, our horticulturist says she’s rarely been more impressed by a plant’s performance! Tuff Stuff hydrangeas offer colorful pink or blue flowers like bigleaf hydrangeas but perform better in cold climates. This means even folks in USDA zones 5 and 6 can rely on seeing these neat, compact plants positively covered with pink or purple mophead flowers all summer and beyond, since Tuff Stuff is a rebloomer. Compact plants are tidy and space-saving, making them perfect for the garden or the landscape.
About the Tuff Stuff™ series: Tuff Stuff are mountain hydrangeas. They are closely related to the popular bigleaf hydrangeas, but they are native to chilly mountainous areas, allowing them to develop better tolerance to cold conditions naturally. Proven Winners ColorChoice Shrubs developed the Tuff Stuff series with an eye toward increased reliability in zones 5 and 6 as well as longer bloom in warmer areas. If you have not had success with bigleaf hydrangeas, we encourage you to give the award-winning Tuff Stuff series a try!DetailsBotanical name:Hydrangea serrata 'MAK20' Patent #: USPP 24,820 Common name: Reblooming hydrangea, Mountain hydrangea Zone: 5-9 Sun exposure: Sun (6+ hours sun) in cool areas; part-sun (4-6 hours sun) in warm climates. Height x width: 2-3' tall and wide Flower color: Pink or purple, depending on conditions Foliage color: Glossy green Season of Interest: Summer-fall Bloom time: Summer, fall Features: Space savers, proven winners, heat tolerant, container plants, best for beginners Uses: Flower gardens, landscaping, specimen, flowering hedge How To GrowSoil: Mountain hydrangeas require well-drained but moist soil. A good layer of mulch is very helpful for minimizing drought stress and conserving moisture. Light: Plants can take full sun (6+ hrs/day) in cooler areas, but afternoon shade is recommended in warm climates. If your plant frequently wilts in the afternoon even though it was recently watered, that may indicate the spot is too sunny for it. Water: Average to abundant (as long as soil is well drained). Space: min. 3' apart Fertilizing: Fertilize in early spring, once the ground has thawed, with a granular rose fertilizer. Make an additional application in late spring/early summer to boost reblooming ability, particularly in colder areas. Winterizing: Do not cut plants back for winter! Doing so will cut off all of the flower buds for the following season. If plants show a lot of dieback in spring, consider moving them, as this indicates the spot may be too cold for the plant. Maintenance & Pruning: Even though Tuff Stuff hydrangeas are reblooming and capable of flowering on old and new wood, for best bloom, it is best to avoid pruning, trimming, or cutting them back. Any dead wood can be pruned out in early spring, once the new growth has begun to emerge and its clear where any winter damage occurred. If plants do not flower reliably, move them to a more protected spot in your yard; early spring is an excellent time to do that. For best reblooming performance, keep plants free of stress so they grow vigorously. New growth is key to a good rebloom! Notes on flower color: The flowers of bigleaf hydrangeas can vary from pink to purple to blue, depending on soil chemistry. You must have both an acidic soil and the presence of aluminum (a naturally occurring soil element) in order for blue/purple color to develop. Get a soil test from your local Cooperative Extension before applying any color change treatment to be certain that it will be effective.

The plants were very small. It will take a bit of time - likes years - before they grow to a decent size.
We are sorry you are not satisfied with your plants! We do note that all of our plants are young on each product page and on our plant sizes page https://www.greatgardenplants.com/pages/sizes . The size and maturity of the plants varies widely depending on the time of the year you purchased and if they were recently trimmed. The important thing when it comes to purchasing plants, whether online or in a garden center, is that they have a full, robust root system, and that's what we prioritize in our greenhouses.

The plants arrived in very good condition and were larger than I expected. They are in the ground and doing well. I planted them where they get late morning and afternoon sun. They are really green and look good.
Have been ultimately happy with my purchase. This hydrangea has been in the ground for a little over a week and is looking good so far.

Nice plant with blooms in first season
My hydrangea is healthy with lots of new growth. It quickly developed a bloom after planting. Hopefully more blooms are on the way!
