Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

Plants growing in Root Pouch fabric containers, showing the breathable woven fabric construction

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

Need a petite pop of color to polish up your undemanding landscaping plan? The answer is... always!

No matter how big or small your space might be, you'll find room for the outstanding flowers of the Proven Winners® ColorChoice® Tuff Stuff Ah-Ha® Hydrangea bush (Hydrangea serrata TUFF STUFF Ah Ha® 'SMNHSDD') will constantly show blooms from late spring into fall! This Mountain Hydrangea is a prolific producer of enormous, flat-topped blooms composed of many double florets. Just one lacecap cluster will nearly fill your hand and grace a bouquet!

These delicate double blooms look just like painted porcelain! Use them as spectacular cut flowers, or enjoy them in your garden setting as they fill with butterflies. Thick, bold foliage is dark green and features finely serrated edges. Its steady strength makes a marvelous contrast to the delicacy of the blooms. And you’ll enjoy wave after wave of bloom as these develop on both new and old wood! Even when not in bloom, you'll be delighted with these compact shrubs! Gain a brilliant fall color display when the leaves turn burgundy-red-purple in autumn.

Like other Mountain Hydrangeas, the color of the florets is determined by your soil pH. You can have bright pastel-pink, rich sky-blue, or any color on the spectrum between the two, depending on your soil. Change the pH to change the flower color. Hydrangea is also surprisingly versatile in many garden applications. You'll get charming season-long color, great form, and outstanding fall color. This high-impact small plant is a wonderful value! Even beginners will have success with this field-tested selection from Proven Winners®.

How To Use Tuff Stuff Ah-Ha® Hydrangea in the Landscape

Although they will tolerate full sun in Northern climates, Ah-Ha® needs partial shade everywhere else. Try them on the east side of your house, or skirting taller trees and shrubs as facer plants. Add a long border that emboldens your foundation with impressive color! You'll pump up your curb appeal in a single step! For a continuous ribbon of blooms, plant them 18 to 24 inches apart on center. You'll measure from the center of one to the center of the next.

These tidy mounding shrubs look incredible in front of larger Hydrangea varieties, too. Mix and match your favorites from all of our extensive options for a grand, easy-care landscape. Incorporate Ah-Ha® into your mixed borders, or create a low, informal hedge. You can even place them in large outdoor containers if you want to elevate the lovely blooms closer to eye level. Try a pair of containers flanking either side of your front door. Pop one under an old evergreen tree to boost the color saturation.

Look for opportunities to make your guests smile. Could you use one or more at your garden gate? Or tuck it behind a fun garden sculpture to heighten the impact. Oh, and by the way...this desirable shrub makes a perfect gift for a plant lover!

#ProPlantTips for Care

Plant Tuff Stuff Hydrangeas in full sun in cooler climates, but give them partial shade where summers get hot. They require at least four hours of direct sunlight a day, and the morning sun is preferred. Be prepared to give them a consistent schedule of even moisture during summer heat too. Place a three-inch layer of mulch over the roots to keep the plant nice and cool. There is blessedly no need to trim the stems. However, you can easily deadhead the spent blooms just below the large flower heads, for a trim and tidy look.

They need well-drained soil but are adaptable to either acidic or slightly alkaline soil. You can expect to see bluer blossoms in the lower pH of acidic soil, and pink in the higher pH of neutral to alkaline. Color changes can occur due to the soil pH over time using garden Sulphur for blue. Try garden lime for pink blooms. Be patient with your experiment, and get an inexpensive soil tester to ensure you don't overdo it.

Full Sun and Partial Shade
Moderately Moist Soil and Loves Mulch
Very Easy Care - Salt and Alkaline Soil Tolerant
Very Limited Pruning Required - Blooms on Both New and Old Wood
Reblooms Prolifically from Late Spring Through Summer and Into Fall

Very healthy nice plants

Very healthy nice plants. Thank you!

Tiny Tuff Stuff is a great compact hydrangea, and it sounds like yours arrived in good shape and ready to grow. If you want to encourage the best bloom next season, go easy on nitrogen fertilizer in late summer so the plant can set buds. Thanks for the kind words, Kris, and enjoy watching it fill in!

Healthy and Well

Mine seems healthy and thriving in 8+ hours full shade in Texas zone 8b. Hopefully it will bloom soon!

Hi Katie - Thank you for sharing and leaving us a review. We love hearing it's thriving in your Texas garden! For blooms, try giving it a light balanced fertilizer in early spring and make sure it's getting consistent moisture during those hot summer stretches. Thank you - Nature Hills Customer Support

This type of plant a slow grower? 5/6/19

Hello Kim,

Thank you so much for reaching out with your question about the Tuff Stuff™ Reblooming Mountain Hydrangea! We truly appreciate your curiosity and taking the time to connect with us.

The Tuff Stuff™ Mountain Hydrangea is known to be a relatively slow to moderate grower, especially in its early years. This is quite normal as the plant establishes a strong root system before putting extensive energy into rapid top growth. Typically, you can expect steady growth each season as it acclimates to your garden environment, and patience will be well rewarded with those beautiful reblooming clusters over time.

To support your hydrangea's healthy growth, be sure to plant it in well-draining soil with some organic matter and water consistently—especially during dry spells. These plants prefer partial shade, but can tolerate full sun in cooler climates. Regular feeding with a balanced fertilizer in spring and mid-summer can also help encourage vigorous new shoots and blooms.

For detailed planting guides and care tips, feel free to visit our blog at NatureHills.com, where you’ll find helpful resources tailored to Mountain Hydrangeas and many other lovely plants.

Thanks again for being a part of our Gill’sedor-Hydrangea community. Please don’t hesitate to reach out if you need any additional guidance—I’m happy to help!

This type of plant a slow grower? 5/6/19

Hello Kim,

Thank you so much for reaching out with your question about the Tuff Stuff™ Reblooming Mountain Hydrangea! We truly appreciate your interest and look forward to helping you get the best from your beautiful plant.

To answer your question, yes, the Tuff Stuff™ is known to be a somewhat slow grower compared to other hydrangeas. This variety is valued for its hardiness and reblooming nature rather than rapid growth. Typically, you can expect gradual but steady progress—especially in the first couple of growing seasons, as it establishes a strong root system. With proper care including well-drained soil, consistent moisture, and partial to full sun (morning sun is ideal), it will gradually fill in and reward you with summertime blooms.

If you’d like, we also have an in-depth care guide for mountain hydrangeas on our website under “Plant Care Tips” that can provide more detailed info. And don’t hesitate to reach out anytime with follow-up questions or if you want personalized advice based on your local conditions.

Thanks again for choosing Nature Hills—we’re here to support your gardening journey every step of the way.
