    'Festiva Maxima' Herbaceous Peony has fragrant double white flower with red speckles. This is a classic Peony which has come back into popular use. It was originally bred for the cut flower trade.
    Height: 34 Inches

    'Karl Rosenfield' Garden Peony has double red blooms. It blooms early in the season (May and June), which makes the double flowers last better because of the cooler temperatures.

    'Shirley Temple' Garden Peony has double white flowers which are very showy. The fragrance is excellent, and since it blooms early in May and June, the double flower performance is dependably good.

    'First Arrival' Itoh Peony was introduced by Roger Anderson of Wisconsin in 1986, but the intersectional Peonies have only become well known fairly recently.  'First Arrival' produces large ruffled pink flowers in late spring and early summer over clean green foliage.  The Itoh Peonies combine the best characteristics of both parents, with mildew resistant leaves and compact tight habits.  Their long bloom period makes them a welcome addition to perennial borders.

    'Bartzella' Itoh Hybrid Peony has sulfur yellow double flowers in May and June, held on short stems above green disease-resistant foliage.  The blooms have red center flares on petals, and 'Bartzella' makes a lovely short cut flower.  Roger Anderson of Wisconsin introduced Paeonia x 'Bartzella' in 1986, after years of hybridizing work.

    PRN Preferred:  A heavy bloomer with bright yellow flowers.  Since is it an Itoh, the foliage looks good all season long.

    'Border Charm' Itoh Hybrid Peony has bright yellow single flowers made more showy by red flares at the base of the petals.  Paeonia x 'Border Charm' blooms profusely in May and June, and makes a lovely short cut flower.  Since Tree Peony is one of the parents, the foliage is a good disease-resistant green, on short woody stems.  'Border Charm' was hybridized by Don Hollingsworth.

    'Cora Louise' Itoh Hybrid Peony is one of the more vigorous Itoh introductions, bred by Roger Anderson of Wisconsin.  It combines excellent hardiness with extremely large showy blooms.  The 10" flowers have white petals which are maroon at the base, surrounding the yellow stamens.  The form is semi-double and the flower production in May is plentiful.  Like all the intersectional Peony hybrids, Paeonia 'Cora Louise' is a wonderful tough addition to the perennial garden.

    'Old Rose Dandy' Itoh Hybrid Peony blooms in May and June, with large single copper petals enhanced by brick-red flares and yellow stamens.  Since 'Old Rose Dandy' is an intersectional hybrid between Tree Peonies and Herbaceous Peonies, the woody stems are quite short and are vigorously covered with handsome disease-resistant foliage.  A cross by Chris Laning in 1993.

    We grow an outstanding selection of unique Garden Peonies, many of which we have grown for years in our own gardens with great delight. Heights range between 2 and 3' and plants are hardy to zone 3 and 4. Unusual flower forms, both double and single, make great cut flowers. All are deer resistant!  Please visit the website for specific varieties and descriptions.

    The Peony World has found a significant Holy Grail with the introduction of beautiful crosses between Tree and Garden Peonies. Toichi Itoh of Japan made the original breakthroughs in 1948, but selections resulting from this work have only recently become available. The flowers range from semi-double to double, in clear bright colors from pink, yellow, and lavender to orange, rose and red. The habit is somewhere between the two species, with short woody stems and vigorous green deciduous foliage. See our availability list for specific varieties.

    'Blackbeard' Beardtongue has beautiful foliage in shades of eggplant and dark purple.  The color stays intense throughout the summer and is topped by deep purple stems bearing showy lilac to pink open faced flowers.  Penstemon 'Blackbeard' makes an excellent long lasting cut flower, and when finished blooming in the garden, the seedheads remain deep purple and attractive.  A Walters Nursery introduction.

    'Denim 'n' Lace' Russian Sage produces sky blue flower spikes for an extended period in mid to late summer.  The lacy blooms are produced on the tips of strong stems with grayish green airy aromatic foliage.  The individual blue flowers on the spikes of 'Denim 'n' Lace' Perovskia are closely spaced so the clumps look fuller than other Perovskias, and the lavender calyces remain showy after the flowers are finished, extending the ornamental qualities.  Excellent drainage is a must for this new introduction from Walters Gardens.

    'Dark Vader' Lungwort produces sprays of delicate open faced flowers in shades of blue-purple and pink.  The blooms appear in April and May, and are displayed over showy fuzzy foliage of dark green with silver spots.  The leaves are rounder and shorter than Pulmonaria var. cevennensis, but are equally mildew resistant.  Pulmonarias prefer cooler temperatures, so they are at their most showy in spring and fall.  Pulmonaria x 'Dark Vader' is a wonderful candidate for woodland naturalizing.

    Appalachian Mountain Mint has attractively fragrant foliage topped by spiky round silver-white flowers in late summer. The blooms are highly attractive to butterflies.

Wet site and shade tolerant, as well as deer resistant.
