Planting & Care

Where to Plant

Sunlight: This shrub thrives in full sun, requiring at least 6 hours of direct light daily. While it can tolerate light partial shade, you will notice thinner foliage and fewer of those signature yellow pea-like blooms if it does not get enough sun.
Soil: It prefers well-drained soil and is famous for its ability to handle poor, rocky, or sandy conditions. If you have heavy clay, plant it on a slight mound or incorporate organic compost to improve drainage, as it cannot stand having "wet feet" for long periods.

Watering Requirements

During the first year, water deeply twice a week to ensure the root system establishes properly in its new home. Once mature, this tree is exceptionally drought-tolerant and tough, but inconsistent water during extreme heat may lead to premature yellowing of the delicate leaflets. Aim to keep the soil moist but never soggy to maintain the best canopy density.

Pruning Tips

Since this tree is grafted onto a standard, you should prune in late winter or very early spring before new growth begins. Focus on removing any "suckers" growing from the base or the main trunk and trim the weeping branches back if they start to touch the ground. Think of this like a haircut that maintains its tidy umbrella shape and prevents the interior from becoming too congested.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the buds begin to swell. Avoid using high-nitrogen fertilizers late in the summer because this encourages tender new growth that will not have time to harden off before the first frost. This plant is a nitrogen-fixer, meaning it creates much of its own food, so a light touch with fertilizer is usually all it needs.

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.

If you are looking for a landscape focal point that combines the architectural grace of a weeping willow with the toughness of a Siberian native, look no further than the Walker Weeping Pea Shrub (Caragana arborescens 'Walker'). This small, deciduous tree—often referred to as the Walker Weeping Peashrub—is a masterclass in texture and form, making it an indispensable tool for designers working in challenging climates.

Spring’s Golden Cascade

The show begins in late spring when the Walker Weeping Pea Shrub erupts in a profusion of bright yellow, pea-like flowers. These blooms are a magnet for early-season pollinators and hummingbirds. Because this cultivar is typically grafted onto a standard (a straight trunk), the branches drape downward in a steep, pendulous fashion, creating a "waterfall" of color that reaches all the way to the ground.

A Fine-Textured Statement Piece

What truly sets the 'Walker' cultivar apart from the species is its incredibly fine foliage. While other Peashrubs have rounded leaflets, the Walker features narrow, linear leaves that look almost needle-like or fern-like. This airy, feathery texture provides a stunning contrast when planted near broad-leafed perennials like Hostas or Bergenia. In autumn, the foliage transitions to a soft yellow before dropping to reveal the intricate, weeping branch structure that adds architectural interest to the winter landscape.

Resilience Meets Elegance

Don't let its delicate appearance fool you. As a member of the Fabaceae (legume) family, this plant is a nitrogen-fixer, meaning it actually improves the soil it grows in. It is exceptionally cold-hardy and thrives in the wind-swept plains and high-altitude gardens where other ornamental trees struggle. Whether you use it as a standalone specimen in a rock garden or as a sophisticated accent near an entryway, the Walker Weeping Pea Shrub delivers high-end aesthetics with low-maintenance requirements.
