Planting & Care

Where to Plant

Sunlight: Provide at least 6 hours of direct sun for the most prolific blooms. While it tolerates partial shade, fewer than 4 hours of sun will result in leggy growth and fewer flowers.
Soil: This vine thrives in rich, well-drained soil that stays cool. If you have heavy clay, mix in organic compost to improve drainage, as "wet feet" will quickly lead to root rot.

Watering Requirements

During the first growing season, provide 1 inch of water weekly to help the root system settle into its new home. Once established, this Clematis is moderately drought tolerant, but inconsistent moisture during hot spells can cause the foliage to brown or the flower size to shrink. Always water at the base of the plant to keep the leaves dry and prevent fungal issues.

Pruning Tips

The Duchess of Cornwall is a Group 3 (Late) bloomer, meaning it produces flowers on new growth each season. In late winter or early spring, cut all stems back to about 12 inches above the ground, just above a pair of healthy buds. This "hard prune" prevents the plant from becoming a tangled mess of bare wood and encourages a fresh flush of vigorous, flower-bearing vines.

Fertilizer Needs

Apply a balanced, slow-release fertilizer or a rose-specific formula in early spring as new growth appears. Avoid using high-nitrogen fertilizers late in the summer because this encourages tender green growth that can be easily damaged by the first frost. Feeding the plant early ensures it has the energy required to produce its signature deep purple blooms all summer long.

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.
