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.

Brilliant Blue Native Wildflower

Blue False Indigo (Baptisia australis) is a stunning American prairie restoration native perennial bursting with true indigo-blue, pea-like blooms that open in early spring. Its flower spikes attract clouds of fluttering butterflies and pollinators while providing an unforgettable color display.

This bushy perennial features deeply divided blue-green leaves on a rounded 3–4 foot tall form. Long-lived and hardy through USDA zones 3–9, it dies back each winter and returns stronger every spring. After the flowers fade, the plant develops intriguing seed pods that rattle in the breeze and add fantastic fall and winter interest to the landscape.

Native to the American Midwest, this plant has been loved for generations. Its tough, adaptable nature and nitrogen-fixing roots improve soil health, while its classic blue blooms have made it a favorite in town squares, prairies, and pollinator gardens across the country.

Key Features

Gorgeous indigo-blue pea-like floral spikes
Tall, bushy form with fine-textured blue-green foliage
Long-lived, cold-hardy native perennial
Lovely cut flowers and fall seed pods
Attracts butterflies and beneficial insects
Great for soil improvement and firewise landscaping
Works beautifully in specimens, backdrops, accents, and tricky sites

Landscaping Uses

A version of the hardy native Blue Wild Indigo, this resilient beauty quickly fills bare spots in borders or mixed perennial plantings. Its tall spikes and rare blue hues make it a striking companion among Cottage, Meadow, and Pollinator gardens.

This perennial pairs beautifully with other beneficial insect attractors and native plants, creating a living pollinator buffet each spring. Use Blue False Indigo to anchor garden beds, soften corners, or provide a bold blue backdrop for later-emerging perennials and flowering shrubs.

Ideal for firewise landscapes, xeric gardens, and even hellstrips, it thrives in poor soil and dry conditions once established. Its deep roots fix nitrogen naturally, improving soil structure for future plantings.

Blue False Indigo is also a delight in Sensory and Children's Gardens. The rattling seed pods have entertained kids for generations, adding playful sound and texture to the fall and winter landscape.

Landscaping Ideas:

Cottage, prairie, and meadow gardens
Pollinator or native restoration sites
Soil improvement and slope stabilization
Firewise and xeric landscaping
Specimens, groupings, and border anchors
Sensory gardens and children's play gardens

Care & Maintenance

Hardy in USDA zones 3–9, this herbaceous perennial thrives in full sun or partial shade. It tolerates a wide range of soil types but performs best in well-drained, moderately moist conditions. Avoid planting in wet, heavy soil.

Once established, Blue False Indigo becomes exceptionally drought-tolerant and low-maintenance. Water regularly during its first year and during hot, dry spells. A little afternoon shade helps protect the foliage during extreme heat.

After blooming, a quick deadheading tidy-up keeps the plant neat. In late fall or winter, prune to the ground and apply a 3–4 inch layer of arborist mulch over the crown to protect the root system. Add compost or organic fertilizer in spring if desired.

Don't forget to order your Nature Hills Root Booster for lifelong mycorrhizal support and healthier root growth.

Care Details:

Planting Time: Spring or fall
Sun Requirements: Full sun to partial shade
Soil Requirements: Well-drained, moderately moist soil
Moisture Needs: Moderate; use the Finger Test to check soil moisture and water regularly during establishment
Mulch: Maintain a 3–4 inch layer of arborist mulch
Fertilization: Not required; enrich soil with compost if desired
Pruning: Deadhead after bloom; cut back in winter
Division: Every 3–5 years if needed
Special Perks: Deer-resistant, heat-tolerant, drought-tolerant, and chill-resistant

No need to order online plants from anywhere else. These folks know how to ship healthy plants!

I received this plant yesterday and planted it this morning. Arrived healthy and the condition is marvelous!

Blue False Indigo is a tough, rewarding perennial once it gets settled in, and it sounds like yours is off to a great start. One tip: give it a season or two to establish before it really hits its stride, but when it blooms, it puts on a show worth waiting for. Thanks for the kind words, Elizabeth, and happy gardening!

The plants were larger than I expected

The plants were larger than I expected, were in great physical condition (packaging was excellent), and healthy. I had them in pots for a few weeks in semi shade and then moved them to full sun. They are growing gangbusters! Very excited about the high quality of the plants I received.

Blue False Indigo is a tough, rewarding plant once it settles in, and it sounds like yours are off to a strong start. The transition from semi-shade to full sun is a smart way to let them acclimate before giving them the conditions they really thrive in. Thanks for the kind words about the packaging too, Paul. We hope you enjoy the blooms for many seasons to come.

These were hard to find in my area, plants arrived healthy and in good size!

nice healthy plant

nice healthy plant, settling in for first year. we'll see how it does next year.

Blue False Indigo does take a season to get comfortable, so your patience will pay off. Once it establishes that deep root system, it tends to put on a much better show in year two and beyond, often with those striking blue-purple spikes that make it worth the wait. Thanks for the update, Mike, and feel free to check back in next season.

Plant came in great condition and is growing well

Plant came in great condition and is growing well. Thanks.

Blue False Indigo is a tough, long-lived plant once it gets settled in, so it is great to hear yours hit the ground running. Thanks for the update, Robin. As a heads-up, the root system really deepens in years two and three, so you should see even more vigorous growth and blooms ahead.

Excellent purchase

The three false indigo plants arrived well packaged, strong and healthy. Can’t wait to see them in blume once established. This was an excellent purchase.

Blue False Indigo is such a rewarding plant once it gets settled in, and those first blooms are really something to look forward to. Glad to hear all three arrived in good shape, Martha. Thanks for choosing Nature Hills, and enjoy watching them fill in over the coming seasons.

Received a strong, healthy plant that is doing wellmakes an excellent addition to the pollinator garden.

Blue False Indigo is such a natural fit for a pollinator garden, and it sounds like yours arrived ready to get established. Once it settles in over the next season or two, you will really see it take off. Thanks for sharing how it is doing, Trevor.

Healthy, perfect plants!

Arrived much quicker than expected, beautifully, securely packaged! Very healthy perfect plants! Thanks for the excellent quality.

Blue False Indigo ships surprisingly well for a plant with such delicate foliage, so it's great to hear yours arrived in good shape. It's a slow starter the first season while it puts down that deep taproot, but once it's established it really takes off. Thanks for the kind words, Marla, and happy growing!

They arrived perfect condition! They are now

They arrived perfect condition! They are now growing beautifully in my garden! Thank you so much!

Blue False Indigo is such a rewarding plant once it gets settled in. Glad yours made the trip well and are putting on good growth. Enjoy those deep blue flower spikes when they come! -- The Nature Hills Team

The plants arrived in excellent condition

The plants arrived in excellent condition. They are about the best (healthy, well grown) plants I have ever received from an online purchase. They are in the ground and doing well.

Blue False Indigo is one of those plants that rewards a patient gardener, and it sounds like yours are off to a great start. Getting them established in the ground quickly is exactly the right move. Thanks for sharing, Lorie. We hope you enjoy years of those deep blue flower spikes each spring.

The plant arrived with a bent stem

The plant arrived with a bent stem. It is alive because I split a straw to support it and placed a plastic fork beside it for support. I hope it survives.

I love it...

This is my third year and I really have enjoyed it. The flowers last for a long time, and even with they are replaced with seed pods, it is still attractive. I just harvested this years seeds, just over a cup full for my girlfriends to start their own plant. My daughter and granddaughter started theirs last year - They say the plant was up over a foot - not bad for their first year!BTW, my plant is over 3 ft high and over 5' wide. Best money I ever spent!!

Hi Stella,

We’re thrilled to hear that it has thrived so beautifully in your garden over the past three years, and your enthusiasm truly shines through. It’s fantastic that the flowers provide such lasting beauty—and how special that the seed pods are now helping your girlfriends start their own plants too! Watching your daughter and granddaughter’s plants grow over a foot in just their first year is impressive and a testament to the hardiness of Blue False Indigo when cared for well.

If you or your gardening friends ever need tips on verifying seed viability or best planting conditions for your next growing cycle, we’d be happy to share some helpful resources. Keeping the plants healthy by watering regularly but allowing well-draining soil sits well with Blue False Indigo, especially since they reward you with vibrant color and interesting seed pods year-round.

Thanks again for trusting Nature Hills with your garden, and happy planting to all generations of gardeners in your family!

Frequently Asked Questions

How large does Blue False Indigo get at maturity?

Blue False Indigo reaches 3-4 feet tall and wide at maturity, forming a rounded, bushy perennial. This long-lived native is hardy in zones 3-9 and returns stronger each spring after dying back in winter. Allow adequate spacing since established plants develop into substantial clumps over time.

Does Blue False Indigo tolerate clay soil or need amendments?

Blue False Indigo thrives in clay soil without amendments, thanks to its tough native prairie roots. This adaptable perennial actually prefers poor soils and will establish well in challenging sites. Shop at Nature Hills for this hardy zones 3-9 native.

What are the watering and moisture needs for Blue False Indigo after establishment?

Blue False Indigo is drought-tolerant once established and thrives in dry conditions. This hardy native actually prefers less water and can handle poor soils better than rich, moist conditions. Water regularly the first year, then back off to occasional deep watering during extended dry spells.

How do I care for Blue False Indigo to prevent flopping or leaning over?

Blue False Indigo's sturdy 3-4 foot structure rarely needs support when grown in full sun with good drainage. The plant naturally develops a strong, bushy form that holds up well to wind and weather. Avoid overwatering and rich soils, which can cause weak, floppy growth in this hardy native.

Is Blue False Indigo deer and rabbit resistant, especially for young plants?

Blue False Indigo is generally deer and rabbit resistant due to its bitter compounds, though young plants may need protection their first season. Once this hardy perennial establishes its 3-4 foot form, browsing becomes rare. Shop at Nature Hills for this native beauty.

What pests or diseases affect Blue False Indigo, like powdery mildew or weevils?

Blue False Indigo is remarkably pest and disease resistant, with few serious issues affecting this hardy native perennial. Occasional aphids may appear on new growth, and root rot can occur in poorly drained soils. Ensure good drainage and avoid overwatering to prevent problems.

What maintenance does Blue False Indigo require, like pruning or fertilizing?

Blue False Indigo requires minimal maintenance once established. This hardy perennial needs no fertilizing since its nitrogen-fixing roots actually improve soil health. Simply cut back the dried stems in late winter before new growth emerges in spring.

How is Blue False Indigo shipped—bare root, potted, or something else—and what size should I expect?

Blue False Indigo typically ships as a potted perennial plant, ready to establish in your garden. Since it grows 3-4 feet tall and wide at maturity, expect a smaller starter plant that will reach full size over 2-3 seasons. Plant in spring after frost danger passes for best establishment.
