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.

Description
Sunny foliage and lasting color! Sometimes the best color display for your yard isn't in the flowers but in the leaves! Introducing the Proven Winners® Sunjoy® Citrus Barberry Bush PP#24,818 (Berberis thunbergii 'Koren') is a prime example of how you can bring brilliant, long-lasting color to your home this year, even without the benefit of flowers!
Sunjoy® Citrus is a Proven Winners® ColorChoice® shrub and an improvement upon the Golden Barberry, Sunjoy® Citrus adds even more vibrant foliage color and does so on a hardy, easy-to-care-for shrub.
It's a hardy little shrub with small leaves that pack a big punch! The chartreuse foliage is a bright stand-out in any setting, providing a sunny burst of color from spring through fall. You won't notice, but the bees and butterflies will see the spring buffet!
Your Sunjoy® Citrus is a deciduous shrub with a naturally compact, rounded habit, but is amenable to pruning if you need your 2-3 foot tall and wide shrub smaller or lower to best suit your landscaping needs!
Planting and Application:
Bold bright color that won't fade or burn in the sun, the juicy Sunjoy® Citrus Barberry is heat and drought-tolerant as well as being at ease in urban environments! Plant several for a low hedge, or just one specimen planting to brighten up a boring corner of your yard!
Deer leave it alone, but wildlife will enjoy it for the dense cover it provides! Set up a hummingbird feeder and a birdbath and enjoy! That means long hedges or groupings not only shelter wildlife but significantly boost the color palate of your landscape! You can even use these vibrant shrubs in large planters and containers!
Sunjoy® Citrus is a good size for use below windows or as your entire foundation hedge, the thorns are sure to deter anyone trying to gain access to first-story windows. Direct foot traffic where you want it with a hedge of these bright barrier shrubs, or create a low privacy barrier that few will want to tangle with around the pool, seating areas, or dividing your front yard from the street!
Compact and hardy, with a standout color that sets the stage for coordinating partner plants, the Barberry is a perfect choice. It easily stands up to pollution! We recommend using an odd number of plants and installing them in a gentle curve or zig-zag for the best effect. Try spacing Sunjoy® Citrus one to two feet apart on center for a solid fill or loosen the spacing however you'd like to create a visual barrier.
- Citrusy Yellow-Green Foliage
- Fine-Textured Compact Shrub
- Reddish Stems & Brilliant Chartreuse Fall Color
- Tiny Yellow Flowers For Bees & Berries For Birds
- Bright Hedges, Foundations, Backdrops, Barriers, Large Planters & Specimens!
#ProPlantTips for Care:
Barberry bushes have the best color in full sun and are tolerant of many types of well-drained soil. Plant with Nature Hills Root Booster in a slightly acidic location. Provide regular water for new plants using the Finger Test, but once established, Barberry is actually quite drought-tolerant! Provide a nice 3-4 inch layer of arborist mulch to protect the top of the roots. You can let it grow freely but it doesn't matter if you trim it to maintain the shape and size you prefer, just prune or shear after flowering.
Unfortunately, the birds adore the berries and do spread the seeds around and in some locations of the country, Barberry does a bit "too well". Find out if you can safely grow these delightfully colorful shrubs in your community. Type in your zip code in our Hardiness Zone Finder, located above the Plant Highlights to find out, or contact your local County Extension Office.
- Won't Burn In Full Sun
- Moderate Moisture & Acidic Well-Drained Soil
- Drought Tolerant Once Established
- Nearly No-Maintenance - Prune After Flowering If Needed
- Heat, Deer & Disease Resistant
