Planting & Care

Where to Plant

Sunlight: Staircase Yellow Lupine thrives in full sun, needing at least six hours of direct sunlight daily to produce its best bloom. While they can handle some light partial shade, too little sun will result in leggy, weak stems and significantly reduced bloom production.
Soil: The ideal soil is lean, loose, and very well-drained, with a slightly acidic to neutral pH. If you are dealing with heavy clay, you must amend the area generously with coarse grit and compost to ensure sharp drainage, as these plants will quickly rot in soggy conditions.

Watering Requirements

During the first season, give your new Lupine consistent moisture to help its deep taproot establish; water deeply when the top inch of soil is dry. Once established, they show good drought tolerance but perform best with supplemental water during hot, dry spells. Inconsistent watering will quickly stress the plant, resulting in smaller, shorter bloom spikes and prematurely browning foliage.

Pruning Tips

Lupines bloom on new wood, and the key to prolonging their show is simple deadheading. Once a flower spike is completely spent, snip the stalk off at the base where it meets the main foliage; this quick action encourages the plant to channel energy into a new flush of side-shoots for repeat blooming. For simple winter cleanup, you can cut the entire plant back to its basal foliage once the leaves yellow in late fall.

Fertilizer Needs

Since Lupines are legumes, they have the fantastic ability to fix their own nitrogen, meaning they are very light feeders and thrive in lean soil. At planting, you can work in a bit of bone meal or a low-nitrogen, high-phosphorus fertilizer to support strong root and bloom development. What to avoid is applying a high-nitrogen fertilizer late in the season, as this will only encourage soft, weak foliage growth at the expense of a hardy root system.

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.

Choosing the Right Size

Size	Plant Age	Best For
Quart	6 mo to 1 yr	Ground covers, perennials, grasses. Budget-friendly for mass plantings.
#1 Container	1 to 2 yrs	Shrubs, perennials, small trees. Value choice for patient gardeners.
#2 Container	2 to 3 yrs	Shrubs and trees where you want faster establishment.
#3 Container	3 to 4 yrs	Most plants. Immediate visual impact. Our most popular size.
#5 and larger	4+ yrs	Specimen plants, privacy screens, maximum instant impact.

Proven Winners® Staircase™ Yellow Lupine

Few plants capture the wild beauty of nature while boasting the refined grace of a cultivated perennial like Staircase™ Yellow Lupine (Lupinus polyphyllus 'Staircase Yellow'). Part of the renowned Proven Winners® series, this stunning variety stands tall with its glowing yellow, pea-like flowers that rise in dramatic spires above lush, deeply divided green foliage!

This herbaceous perennial forms upright, statuesque clumps, reaching 18-24 inches tall and wide. Its palmately compound leaves, meaning each leaf resembles an open hand with multiple leaflets, add texture and visual interest even when not in bloom.

Lupines, beloved for their ability to fix nitrogen in the soil, thrive in cool climates and are best suited for USDA growing zones 4-8.

Can Staircase™ Yellow Lupine be grown in containers?

Yes, Staircase™ Yellow Lupine grows well in containers given its compact 18-24 inch size. Choose a deep pot (at least 12 inches) to accommodate the taproot, and ensure good drainage since lupines dislike wet feet. Best success in zones 4-8 with cool conditions.

How much moisture does it require?

Staircase™ Yellow Lupine prefers consistent, moderate moisture but is drought-tolerant once established. This perennial thrives in zones 4-8 with well-draining soil that doesn't stay waterlogged. Water regularly during its late spring to early summer bloom period, then reduce frequency as it matures.

What is its cold hardiness temperature?

Staircase™ Yellow Lupine is hardy in USDA zones 4-8, tolerating winter temperatures down to -30°F. This Proven Winners® perennial thrives in cooler climates and benefits from cold winter periods for best flowering. Shop at Nature Hills for reliable cold-hardy lupines.

How should it be mulched?

Apply a 2-3 inch layer of organic mulch around Staircase™ Yellow Lupine, keeping it several inches away from the crown. This cool-climate perennial benefits from mulch that retains moisture while allowing good air circulation. Refresh the mulch each spring before the late spring bloom period.
