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.

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.

This Proven Winners® plant is long in style, but short in stature. We're sure you'll appreciate it all year-round!

Dark green, lustrous fine textured foliage sports beautiful red blushed new growth. This is a female cultivar, but currently, no males have been introduced to pollinate it so it is grown as a broadleaved evergreen that does not set fruit. Dense and fluffy, this Inkberry maintains good branching right to the ground, Gem Box® always looks classy and full!

The fine-textured, glossy, lance-shaped leaves bring a year round dark-green sheen and a high-style look to your garden throughout USDA growing zones 4-9 adding an amazing designer touch to your landscape! It will tolerate several hours of shade a day. That makes it even more versatile to use near ornamental trees, patios, and foundations.

Planting and Application:

Create backdrops, and garden definition, adding formal structure to beds or borders without the designer price tag! Try them in small containers along a walkway or at your entry. Gem Box® Ilex remains neat and tidy, and you'll love using the mounded structural accent in just about any garden bed! These bring a lovely quality to containers and planters.

That steady year-round green just looks so handsome and the dainty dark-green leaves retain that glossy sheen! Fitting into formal beds as well as they do loose country plantings! Evergreen shrubs are amazing facer shrubs to hide the bare legs of your larger foundation plants.

For a solid low hedge, plant them 1 - 3 feet on center. You'll measure from the center of one shrub to the center of the next. As your budget allows, plant them closer together. They'll fill in faster for you! You can also try a staggered zig-zag to create a mass planting on a slope or a large bare patch. The plants will grow to create a low-maintenance groundcover.
