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.

Jackmanii Clematis Adds Dramatic Purple Flair

The Jackmanii Clematis (Clematis x jackmanii) is a legendary garden performer beloved for its stunning deep purple blooms and vigorous vining habit. This hybrid Clematis, introduced in 1862, is one of the oldest and most popular large-flowered Clematises in cultivation today!

Jackmanii is a reblooming variety that bursts into bloom in early to mid-summer and often returns for an encore in late summer. Each flower boasts a royal richness, up to 6 inches across, and is adorned with velvety petals surrounding creamy stamens!

This deciduous woody vine grows 8 to 12 feet tall and about 3 to 6 feet wide, quickly covering supports with its twining leaf stalks. The leaves are compound with 3 to 5 leaflets, in a dark, lush green hue that provides an elegant backdrop for the saturated purple blooms!

Key Features

Large, royal purple flowers up to 6 inches wide
Reblooms from early summer to late summer
Deciduous woody vine that grows 10–12 feet tall
Cold-hardy in USDA zones 4–8
Loved for trellises, obelisks, and fences

Care and Maintenance

Jackmanii Clematis is a deciduous woody vine that is easy to grow once established. It’s sun-loving, fast-growing, and adaptable across many conditions with a few tricks from Ma Nature.

Although it goes dormant in winter, it re-emerges each spring ready to climb again, and unlike some Clematises, it blooms on new wood, making pruning a breeze. Jackmanii Clematis is a hardy hybrid from England, bred from Clematis lanuginosa, Clematis viticella, and other wild species. It thrives in USDA growing zones 4 through 9, showing excellent cold-hardiness and moderate heat tolerance.

Planting Time: Spring or fall. Read how to Grow and Train Clematis Here!
Sun Needs: Full sun to part shade (blooms best with 6+ hours of sun)
Soil Needs: Moist, well-drained soil; avoid heavy clay unless amended; prefers neutral to slightly alkaline pH
Moisture Needs: Moderate; keep evenly moist but never soggy
Arborist Mulch: Use a 3–4 inch layer of arborist mulch to cool the roots; consider underplanting with low-growing perennials to shade the root zone. Like most Clematises, it adores cool roots and warm tops, a signature preference of this genus.
Fertilization Needs: Apply a balanced, slow-release fertilizer in early spring
Pruning Info: Group 3 Clematis. Cut back hard in late winter/early spring to about 12 inches above ground
Special Needs/Growing Tips:

Deer-resistant
Not usually troubled by pests or disease

Good size and arrived very healthy

Good size and arrived very healthy.

Jackman Clematis is such a rewarding climber once it gets established, so starting with a healthy, well-sized plant really sets you up for a strong first season. Thanks for sharing that, Andrew. We hope it puts on a great show for you this year.

Very satisfied

Plant came very quickly was packaged nicely it’s growing very very well very pleased with it

It arrived dead

It arrived dead. 2 of the 3 plants in this order were so brown and crunchy that I have to believe you ran them through a dehydrator before packaging for shipment.

In my first order this year, 2 were shipped a couple months before planting season, so it wasn't shocking that they didn't survive until planting time. (Of course that was outside the 45-day warranty so not covered, and I just lost money.) But these arrived within a couple weeks of when I ordered, and they appeared to be in shipment for a few days, so they had to have died before shipment.

Please send my refund now. I requested it on June 12th, and have seen no sign that you are processing it.

Beautiful Jackman Clematis!

Frequently Asked Questions

How do I care for Jackman Clematis, including watering, sunlight, and fertilizer needs?

Jackman Clematis thrives in full sun with consistent moisture and well-draining soil in zones 4-8. This vigorous vine benefits from annual spring fertilizing and prefers its roots cool and shaded while the top growth reaches for sunlight. Mulch the base heavily and provide sturdy support for its 8-12 foot climbing habit.

What are the pruning requirements for Jackman Clematis, and which group does it belong to?

Jackman Clematis belongs to pruning Group 3, requiring hard pruning to 12-18 inches in late winter or early spring. This promotes vigorous new growth and abundant blooms on current-year wood. Cut back after the first hard frost when the vine goes dormant.

Is Jackman Clematis evergreen or deciduous?

Jackman Clematis is deciduous, losing its leaves each winter in zones 4-8. This woody vine dies back seasonally but returns vigorously each spring to reach 8-12 feet tall. Expect fresh green foliage to emerge in spring, followed by those spectacular 6-inch purple blooms in early summer.

How is Jackman Clematis shipped, and what should I expect upon arrival?

Jackman Clematis ships as a dormant bare-root plant or potted vine, depending on season. You'll receive a hardy specimen ready for zones 4-8 that will reach 8-12 feet at maturity. Plant immediately upon arrival and provide sturdy support for this vigorous climber.

Will Jackman Clematis survive winter in cold zones, and how do I protect new shoots?

Jackman Clematis is cold-hardy in USDA zones 4-8 and will survive winter in most cold zones. This deciduous vine dies back naturally in winter, then regrows from the base in spring. Apply 3-4 inches of mulch around the base after the first hard frost to protect the root system.

Is Jackman Clematis deer or rabbit resistant?

Jackman Clematis is not typically deer or rabbit resistant, as these animals often browse on clematis vines and foliage. The vigorous 8-12 foot growth habit means damaged areas usually recover quickly during the growing season. Consider fencing young plants or using deterrent sprays in areas with heavy deer or rabbit pressure.
