Press Releases: First Look! New Proven Winners Perennials for 2021-2022 Announced 

  • Amsonia ‘String Theory’

    (Bluestar) People have loved ‘Storm Cloud’ and we are now pleased to offer a complementing threadleaf Amsonia to the Proven Winners program. ‘String Theory’ can be described as a compact version of the industry standard Amsonia hubrichtii. The compact habit is covered with light periwinkle blue flowers in late spring, flowering later than ‘Storm Cloud’. While other Amsonia can often display chlorotic leaves, ‘String Theory’ displays healthy dark green leaves throughout the summer. We have observed the same brilliant golden orange fall color as you would expect from A. hubrichtii.

    Height: 18-22” Spread: 32-36” Zones 4-9

     Clematis ‘Stand by Me Lavender’

    (Bush Clematis) Riding on the coattails of the much-talked-about ‘Stand by Me’ comes a new color for the Bush Clematis type! This variety has the same performance as ‘Stand by Me’ but with a lavender shade of flowers to join the original’s blue. Dark purple buds open to lavender purple, bell-shaped, nodding flowers. Attractive cream thread-like seed heads follow. Broad, green foliage. This plant benefits from staking, cages, or neighboring plants for support.

    Height: 34-38”  Spread: 24-36”  Zones 3-7

     Geranium pratense ‘Boom Chocolatta’

    (Hardy Geranium, Cranesbill) This perennial certainly does have a chocolatey look! This Geranium pratense hybrid has rich, dark bronze leaves and an upright habit, with blue-purple flowers covering the top of the habit, starting in early summer. Compared to older genetics, 'Boom Chocolatta' is more vigorous, and has a very refined habit. Use it as a contrast with green-leaved plants in your sun garden!

    Height: 24-26”  Spread: 28-30”  Zones 4-8

     Heuchera DRESSED UP™ ‘Evening Gown’

    (Coral Bells) ‘Evening Gown’ is the inaugural member of a new series of Heuchera for Proven Winners that is prized for its incredible ruffled leaves, a feature that makes it a welcome texture for any landscape or container. Huge 6”, glossy black leaves have ruffled margins and form a substantial mounded habit. Best color and performance in part shade. Substantial flower scapes hold pink buds that open to white flowers.

     Hibiscus SUMMERIFIC® ‘Edge of Night’

    (Rose Mallow) One of our most hotly anticipated additions to the SUMMERIFIC® lineup in recent years! At only 3-3.5 feet tall, this is our most compact Hibiscus to date. 7-8” bubblegum pink flowers have overlapping petals and darker pink veining for a dramatic 3D effect. Jet black foliage is the darkest we’ve seen on a Hibiscus and contrasts nicely with the green flower calyxes and red veining and petioles. Compared to ‘Evening Rose’, this has darker foliage, a more compact habit, and brighter pink flowers. Best color and performance will be in full sun.

    Height: 3-3.5'  Spread: 4-4.5'  Zones 4-9

     Hosta SHADOWLAND® ‘Hope Springs Eternal’

    All gardening is an exercise in optimism, and ‘Hope Springs Eternal’ is appropriate name for a hosta that will bring joy year after year. Heart-shaped, blue horizontal leaves have a crisp creamy white margin and form a formal habit. Its most notable feature are the incredible ruffling on the leaves that undulate all the way to the pointed tips. Near white flowers in midsummer.

    A majestic, variegated large hosta that will capture the hearts of any gardener who showcases it in their garden. Medium green, heart-shaped leaves have white centers and light green intermediate streaking between the center and margin. The contrast between the margin and the center is dramatic and refined. Near white, tubular flowers have a lavender pattern in the center of the petals are borne on thick, upright, tall stems. The flowers were notably the most attractive we’ve seen on a hosta.

     Leucanthemum superbum AMAZING DAISIES® ‘Banana Cream II’

    (Shasta Daisy) This improvement on the classic ‘Banana Cream’ takes all the characteristics that gardeners love and kicks it up a notch. Just like the original, flower buds are lemon yellow and eventually brighten to creamy white. Improvements include being more floriferous, holding the yellow color longer, a more appealing habit, and earlier to start flowering. Growers will love that the vernalization week requirements are much shorter—we recommend 4-6 weeks for best performance, although we have observed flowering without vernalization.

     Leucanthemum superbum AMAZING DAISIES® ‘Spun Silk’

    (Shasta Daisy) Like the beautifully intricate creations of arachnids, ‘Spun Silk’ brings a wild new look to the classic Shasta Daisy. Narrow petals with fringed edges create the “spider” look, with the 4.5” graceful white flowers topping a medium-sized habit. The perfect choice for bringing new and interesting texture to the garden. ‘Spun Silk’ requires vernalization to bloom; we recommend 6-8 weeks minimum.

     Monarda ‘Pardon My Lavender II’

    (Bee Balm) An improvement on the original, ‘Pardon My Lavender II’ replaces ‘Pardon My Lavender’ in the catalog. Compared to the original, this has more vigor, is more polished, and has better disease resistance. No room for the tall, bushy, traditional Bee Balm in your garden?  Now there’s a compact selection that’s easy to tuck into the front of your sunny border and combination containers.  Reaching just a foot tall at maturity, this compact selection forms a well-branched clump of deep green, glossy foliage. In midsummer, lavender purple flowers sit just at the top of the foliage. Though the plant may be smaller, the flowers are the same size as taller selections, measuring a full 2½-3" across. They add a cool splash of color to the border in high summer.

Slightly running, but controlled and refined habit. In midsummer, intense rose pink flowers sit just at the top of the foliage. Though the plant may be smaller, the flowers are the same size as taller selections, measuring a full 2½-3" across.  They add a bright splash of color to the border in high summer.

Just like its predecessors in the Opening Act series, ‘Opening Act Romance’ blooms 2-3 weeks earlier than Tall Garden Phlox (Phlox paniculata) and is mildew and disease resistant. ‘Opening Act Romance’ blooms later (1-2 weeks) than ‘Opening Act Ultrapink’. If sheered back, these plants will rebloom later in the season. Spreads slowly by stolons.

We have grown to be one of North America’s largest wholesale perennial growers with a reputation for superior quality, excellent service, and cutting edge new varieties. Our breeding program works with almost 100 different genera of perennial and has introduced hundreds of cutting edge new perennials to date. This combination of high quality product and unique plant introductions has led to a partnership with Proven Winners® as the home of Proven Winners® Perennials.


The Walters Gardens, Inc. story began in 1942 when Dennis Walters and his new bride, Harriet, took over the family perennial business from Dena Knoll, Harriet's mother. With the help of his four brothers, Dennis expanded the company to include bare root, potted, and packaged perennials, and built one of the industry's first tissue culture labs at Walters Gardens, Inc. in the mid 1970s.

Today, the company is run by the second and third generations of Walters aided by numerous other family members and dedicated employees including plant health experts, skilled horticulturists, capable customer care and marketing staff, and a pool of sales representatives and brokers nationwide. Our company has grown from a small farm of less than five acres worked by just a few men to a multimillion dollar corporation with over 200 employees, 1,500 acres of land, and 500,000 square feet of greenhouse space. Over 18 million perennial liners are shipped annually to independent garden centers, wholesale growers, landscapers, and municipalities across the US and Canada. Each year, approximately 100 new items are added to our catalog of over 1,000 bare root and plug perennial liners.

Plug Liners

Most of the plants offered in our catalog are grown in plug form. Our plants are grown in standardized tray sizes, including 20, 30, 72, and 128 count. The majority of our plugs are easy to transplant Elle Plugs, while others are traditional loose fill plugs. The type of plug used is based upon the specific needs of the plant.

Larger 20 and 30ct plugs are best suited to customers looking for faster turnaround times and sales the same season. Smaller 72 and 128ct plugs are better suited for growers looking to produce larger quantities at a lower input cost. They are typically planted in summer for sales the following spring.

We offer a number of perennials in economically priced 72 and 128ct plugs which are ideal for growers looking to produce larger quantities of their best selling items at a lower input cost. Don’t see exactly what you’re looking for? We accept custom orders for 72s and 128s (minimums apply). Please contact us for details.

One of the most common questions we hear is why Deep Cell vs. Elle? We trial every perennial in both trays to determine which option provides the best product for our customers. Our Elle trays hold plug liners that have been wrapped in a thin paper sleeve designed for ease of transplant. The sleeve is biodegradable and in a healthy environment does not hinder root development. Deep cell trays hold loose fill plug liners and have the added depth some perennials need to encourage better root development.

Mangave is a relatively new phenomenon, as a cross between the genus Manfreda and Agave. These rare hybrids combine the best of both worlds: the better growth rate and the interesting patterns of Manfreda, and the habit and refinement of Agave. Join Laura, our trials manager, to learn some Mangave production tips.
