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.

Bright pink eyes and flouncy light pink flower clusters, the Luminary® Opalescence Tall Garden Phlox (Phlox paniculata 'Opalescence') from Proven Winners® has big fragrant flowers that butterflies and bees, and even hummingbirds adore! You will adore these as well! Tall, elegant, and colorful beacons, Garden Phlox are classic garden and border plants!

Backed by dark-green foliage that makes them stand out more, an added bonus is that these blooms are held aloft at a height of 2-3 feet tall! These leaves are mildew-resistant and have dark backgrounds to the vivid blooms all summer. These perennials are lush fillers and thrillers anywhere they're planted!

Garden Phlox might be tall, but they won't take up much space in the garden, so they're great for mixed pots and planters as thrillers and bold color! These are upright, strong stems that look amazing in floral bouquets as well as in the garden. Just be sure to plant a few extra so you and your pollinators can still enjoy them outdoors!

Planting and Application:

Tall Garden Phlox has a small footprint but a big impact in cottage beds and perennial borders! Dramatic pink flouncy blossoms like these are perfect in pollinator and cutting gardens, and as tall vertical elements in garden beds and containers alike!

Opalescence is a great back border plant, where its dark foliage becomes the perfect backdrop for other perennials in the garden. These are easy-care plants and require very little upkeep, so don't be afraid to plant en masse and create woodland or wildflower plantings without much worry that deer will devour them.

#ProPlantTips for Care:

Phlox are hardy down to growing zone 3 and thrive up to zone 8 heat. Doing great in full sun in cool zones but appreciating partial shade and afternoon protection in hotter climates. These herbaceous perennials appreciate good Air Circulation and well-drained soil. Be sure to give them supplemental water during their first year and apply water in a prolonged drought. Apply a three-inch layer of mulch around your plant, but make sure to pull it back from the stems.

Prune Tall Phlox right after the blossoms fade and tidy up the mounds in late autumn after frost. While no plant is truly deer resistant, they do not prefer the taste of these plants. But, if you live in Deer Country, be sure to use Deer Repellent during planting, guided by the instructions on the label.

Moist Well-Drained Soil
Mulched Beds
Prune to Ground In Late Fall
Fairly Deer Resistant

Fantastic Phlox!!

These phlox are fantastic. Planted last year, they bloomed all summer and into the fall providing the color I wanted while other perennials waned. This spring, they're back after a tough winter and I look forward to more color.

Hi John,

Thank you so much for your wonderful feedback! We’re delighted to hear that your phlox thrived and provided vibrant color throughout the summer and fall. It’s especially great to know they bounced back well after a tough winter—phlox are such resilient plants when cared for properly. To keep your phlox blooming beautifully again this season, make sure to deadhead spent flowers throughout the summer, as this encourages continuous blooms. Also, light fertilization in early spring can help support healthy growth.

If you need any tips or supplies for ongoing care, don’t hesitate to reach out or explore our gardening resources online. We're always here to support your flourishing garden!

Bloom on,
The Nature Hills Plant Knowledge Team

Luminary® Opalescence Tall Garden Phlox is hardy in USDA zones 3-8. It thrives in full sun in cooler zones but benefits from partial shade and afternoon protection in hotter climates. Shop at Nature Hills for this versatile perennial.

How often should I water Luminary® Opalescence Tall Garden Phlox after planting?

Water newly planted Luminary Opalescence daily for the first week, then 2-3 times weekly until established. These hardy perennials (zones 3-8) need consistent moisture their first season to develop strong roots. Once established, they're quite drought tolerant and only need watering during dry spells.

How do I plant Luminary® Opalescence Tall Garden Phlox for best results?

Plant in full sun in zones 3-6, or partial shade in zones 7-8 for heat protection. Space 18-24 inches apart to allow air circulation around the mildew-resistant foliage. Plant in spring after last frost in well-draining soil, watering deeply but infrequently once established.

How should I prune or maintain Luminary® Opalescence Tall Garden Phlox in fall or winter?

Cut stems back to 2-3 inches above ground level after the first hard frost in zones 3-8. This prevents disease and encourages vigorous spring growth. Shop mildew-resistant varieties like Opalescence at Nature Hills for easier maintenance.
