Digging Dog Nursery Perennial Plants Intro Drawing

Perennials offer endlessly fascinating variety in terms of flower color, scent, foliage texture and hue, and overall form. In spring, the excitement begins as plants emerge, often rapidly attaining full size. This is a good time to fertilize. In summer, sit back and enjoy the bounty, remembering to deadhead and water.

We've tried to present a variety of perennials with fall blooming periods to extend summer's pleasure. In autumn we reevaluate and perhaps relocate. Winter dormancy is the right time to take divisions (usually every second or third year), increasing your collection and possibly a friend's.

One reason for noting a perennial's place of origin is to remind us that perennials are really wild flowers, and our garden unites the finest from meadows, mountains, and forests all around the globe. When planting, it's wise to combine plants with similar cultural needs, and then work within these guidelines for aesthetically pleasing combinations.

We hope our individual recommendations will help. Many of our perennials are varieties that are hard to find, and we think all of them are in some way outstanding.

Digging Dog Plant Nursery Perennial Border

Acaena

Goose Leaf

Our selections of this enchanting, ground-hugging evergreen from New Zealand feature diminutive leaves with a ferny delicacy. Lifting on short stalks above the foliage, globe-shaped seed heads—small thornless “burrs”—are colored a brownish red. Adapted to almost any well drained location, plant it as a cover for your bulb bed, situate it along pathways, perch it on a garden wall or let it creep around paving stones.

<i>Acaena inermis</i> ‘Purpurea’

Colored in a purple-gray shade reminiscent of overripe plums, this enchanting ground-level evergreen from New Zealand sprouts delicate low-lying foliage that sends forth globe-shaped seed heads—small brownish red thornless spheres on short stalks. ‘Purpurea’ warmly interweaves a planting of Dianthus ‘Mendlesham Maid’, Scutellaria ‘Texas Rose’ and Carex glauca above our rock wall.

Acanthus

Bear’s Breaches

The pagoda-style tower of white and purple hooded flowers rises proudly from a textural, 18 in. tall lustrous rosette, fashioned with finely chiseled dark forest green leaves. Though Acanthus caroli-alexandri's origins are uncertain, some say it's a form of Acanthus hungaricus, while others claim it's a hybrid between Acanthus spinosus and Acanthus hirsutus its bold lacy accents are sure to turn heads in a tight spot or a more expansive planting.

Ideal for fresh and dried arrangements, up to a dozen mighty spires muscle upwards with a stylish long-lasting display of hooded pure white flowers nestled amid prickly purple bracts. Varnished, deeply scalloped dark green leaves define the valiant compact clump, which makes a breathtaking specimen in mixed borders.

<i>Acanthus spinosus</i> <i>Acanthus spinosus</i>

Hailing from the eastern Mediterranean, this bold  statuesque perennial is as strong as a gladiator, and equally commanding. Held on lengthy stalks, the deeply divided, 2 to 3 ft. long leaves are glossy and very dark green. Spiny-looking, though not too sharp, the leaves’ erect yet arching architecture were the inspiration for the decorative crown on Corinthian capitals. Mysterious, 2 ft. tall wands of Foxglove-like flowers rise above the imposing mound. Long-lasting and excellent for arrangements, each white-lipped blossom is anchored by a green-gray bract and nearly hidden by a decorative, hood-like purple calyx.

Achillea

Achillea

Yarrow

Legend has it that Achilles used this plant to heal his soldiers’ wounds after battle. As a folk remedy, its leaves are prescribed to soothe abrasions and toothache. We find this sturdy, dependable plant the perfect remedy for many design situations. The broad, flat flower heads project horizontal elements, their colors blend­­ing with other perennials. Spicy smelling, fern-like foliage and strong straight stems add to overall attractiveness. Spreading and drought tolerant, Yarrow seems to thrive on neglect, can handle ocean spray and will bloom again in the fall if cut back in midsummer.

<i>Achillea</i> ‘Alabaster’

Named for the ivory-white color that the pale yellow flowers turn with age, ‘Alabaster’ blooms late and, with dried seed heads, keeps our interest well into winter. Its form is stiff and upright and its foliage gray-green, making an excellent neighbor for Aster ‘Little Carlow’ or grasses such as Miscanthus sinensis ‘Nippon’.

Blooms August–October.

<i>Achillea</i> ‘Hella Glashoff’

In clear creamy-lemon hues, the large flattened umbels are lifted on short, firm leafy stems above a lace-like delicacy of green foliage. Later to bloom and not as tall as most of our other Achillea offerings, this softly colored AGM winner is an exemplary choice for smaller gardens, given border frontage and Aster ‘Twilight’ as a companion.

Aconitum

Monkshood

First cultivated in the mid-1500s, Aconitum derivatives were used as both a medicine and a poison, and an unwanted husband might have easily met his end while drinking his dear wife’s tonic. Simply medieval! Leaves, stems and roots are poisonous, but the stately Aconitum still deserves a place in our gardens because of the unusual blooms it hoists in abundance on stalwart stems. An excellent cut flower, unique for its large draped sepal, Aconitum loves cool summer nights, moist, but not wet soil and protection from the heat of the day. Perfect in the border or at woodland’s edge, their bold presence makes an engaging companion to Anemone, Helenium and late-blooming Persicaria.

A bushy forest-green foundation of lustrous deeply-fingered foliage plus staunch wide-branching stems bolsters the unique bicolored blooms. Coveted by pollinators, floral designers and plantspeople alike, this supposed Aconitum variegatum and Aconitum nepellus descendant premiers tall scene-stealing spires, housing copious, close-set hooded white flowers toned with soft blue hues and indigo-violet edges. ‘Bicolor’ boasts first-rate AGM notoriety for its stately vertical profile and midseason blooms that illuminate plants such as Phlox ‘Gzhel’ and Heracleum ‘Pink Cloud’.

Ajuga

Bugleweed

From the Latin abigo, to drive away, Ajuga was thought to drive away disease. To some of us that disease is winter; the remedy is Bugleweed, herald of spring, with its clear blue, white or pink flowers. The crisp, crinkled foliage hugs the ground for a quick-spreading, evergreen carpet. Use Ajuga en masse under a high canopy, or to soften the hard edges of walls and paving. A moisture-retentive soil is recommended.

Alchemilla

Lady’s Mantle

You might not transmute gold with Alchemilla, but foamy clusters of tiny star-like flowers in brilliant chartreuse will materialize above beautifully scalloped, slightly toothed foliage. A contrast of forms, Alchemilla was used to collect dewdrops in the medieval preparation of the Philosopher’s Stone. We find the way moisture collects and moves like mercury on the pale green leaves always magical. Whether fresh or dried, the flowers are a welcome addition to any bouquet. 

 

Indigenous to Greenland and Newfoundland, this snug low growing Alchemilla combines elfin charm with enduring resilience. The petite dark green leaves are distinguished by deep separate lobes, delicate silver margins and soft hairy undersides beneath a dainty effervescence of clustered chartreuse flowers perched on short stems. Touting age-old curative properties plus superb cold hardiness, Alchemilla alpina’s diminutive mound can be cozied against rocks, along paths or atop stone walls where it abides poor, lean soil but cherishes well-drained, somewhat moist niches.

Adored by bees, florists and plant aficionados, ‘Globemaster’s otherworldly blooms work well when planted amid perennials such as Verbascum nigrum ‘Album’ and Alchemilla ‘Robusta’, so its strapping gray-green leaves will be hidden once they decline.

Blushed with a medley of lovely old-fashioned pinks, this beauty came to us from a U.C. Davis college professor years ago. Its jungle-like foundation of handsome foliage culminates in rose-hued flowers warmed by butter-yellows, creamy streaks and dark wine-colored markings. Claret brush strokes and just a hint of green engrave the petals’ exterior.

Both a florist shop’s darling and a star in the garden, ‘Henry’s Violet’ struts dandy bicolored blooms. Vivid violet-hued outer petals reveal white throats with burgundy flecks, a chartreuse dusting, flaxen highlights and several prominent magenta-laced purple blotches. Sturdy long stems and a flood of fresh green foliage support the large open-funneled flowers that cavort amid Stachys ‘Hummelo’, Salvia ‘Whirly Blue’ and Kniphofia ‘Minister Verschuur’ above our stonewall.

Boasting a compact tailored habit, improved winter hardiness and a generous long-lasting floral fete, this sunshine-colored beauty is a recent member of the Majestic series from breeder Turcieflor in the Loire Valley of France. Firm stems clothed in lusty lance-shaped green foliage bolster the ample terminal clusters of funnel-shaped canary-yellow blooms with rose-colored blushes plus burgundy striations, which serve as nectar-guides for beneficial pollinators.

<i>Alstroemeria</i> ‘Marjorie’s Hybrid’

Ample Lilyesque blooms feature a cozy mingling of dusty mauve, blushed salmon and sunburst gold areas peppered with wine-colored bars.

A lusty presentation of shiny green foliage anchors large abundant clusters of rose pink blooms, flaunting a decidedly feminine aspect.

Salmon-tinged petals are darkened by dusty-rose shades on the backside and set aglow inside by 2 orangey pink-tipped upper petals painted with sunshine hues and small crimson striations. Guaranteed to charm, this Alstroemeria’s lush, medium green base is a soothing counterpoint to its fanciful flowers.

A prized outcome from the late Fred Meyer’s efforts to improve upon a group of European Alstroemeria hybrids, ‘Rachel’ is named after former nursery owner Judy Wigand’s granddaughter, and is renown for her tidy, compact stature and pretty purple blooms. Eye catching lemon-yellow shades give a sunny lift, while snazzy maroon dashes and dark violet splotches enhance the good-sized flower clusters.

Atop a short and shiny, thickset foliar clump that’s quite hardy, the sumptuous orchid shades look especially boisterous when matched with other Alstroemerias such as ‘Yellow Friendship’ and ‘Princess Victoria’.

<i>Alstroemeria</i> ‘Red Valley’

A passionate drama is played out when this cultivar’s seductive blooms unfurl in sassy shades of bright red with scarlet overtones. Staged above thick, ribbed green foliage, the bold floral presentation is heightened by cocoa-colored streaks amid primrose-yellow splashes on the upper petals. ‘Valley Red’ produces flowers that are far more sultry than ‘Princess Victoria’s and makes a sublime companion for reddish chocolate-leafed Eupatorium ‘Chocolate’.

Amsonia x ‘Blue Ice’ (P-1969)

Each $10.75

PREORDER FOR APRIL 2024

<i>Amsonia</i> x ‘Blue Ice’

Springing forth in a seedling block of Amsonia tabernaemontana at Sunny Border Nursery, this energetic compact perennial has an unresolved lineage, with some speculating that either Amsonia montana or Amsonia orientalis may be a parent. What’s for certain is the fact that its flowers are the bluest, most vibrant and longest blooming ones amongst the genus. The pyramidal-shaped terminal clusters of navy-colored buds and starry lavender-blue blooms garnish a refined dense mound clothed in narrow, willow-like dark green leaves. ‘Blue Ice’s easily maintained habit beams brilliant yellow fall color, looks its best when massed and makes a spiffy deer-proof addition to rock work, borders or woodland peripheries.

Blooms May–June

<i>Amsonia hubrichtii</i>

Too long ignored, this hard-to-find perennial adds pleasing texture to the border and delicacy to a bouquet. In early summer, bushy clumps of elegant, upright stems are crowned with steel blue buds and starry gray-blue flowers held in graceful umbels.

We are especially captivated by the willowy needlelike leaves, which eventually burnish to a brilliant gold, and together with the persistent chocolate-hued seed heads, bestow a rich autumn show. A southwestern U.S. native, Blue Star is undemanding and long-lived in any garden soil.

PREORDER FOR MAY 2024

<i>Anchusa azurea</i> ‘Loddon Royalist’

“Of deep glorious color” are the words Graham Stuart Thomas, legendary author and horticulturist, uttered to describe the deep blue tint, vividly imbuing large, edible forget-me-not like blooms, and deeming ‘Loddon Royalist’ the bluest of them all! Selected more than 50 years ago at Britain’s Loddon Nursery, this garden-worthy Borage family member and Mediterranean denizen sprouts a stubble-surfaced dark green basal rosette below infamous white-ringed dimple-centered blossoms, which perch on lax stems and make a tasty culinary garnish. Verbascum ‘Sixteen Candles’ and Geum ‘Prinses Juliana’ are glowing companions for the ever-blue floral wonders, while light sandy or sharp-draining soil plus a shearing right after the flowers have faded will ensure its long-lived vigor.

Anemone

Wind Flower

“The floure never openth it selfe, but when the wynde bloweth,” wrote William Turner, in A New Herbal (1560). In our garden, however, we enjoy the buttercup-shaped flowers in any weather, windy or not. Tasteful and deceptively delicate looking, Anemone is also tough and undemanding. Most will multiply readily in rich sandy loam, and are perfect for naturalizing in a woodland setting.

<em>Anemone Fantasy</em>  ‘Snow Angel’

Centered by ebullient yellow stamens, a flurry of semidouble snow-white flowers prances above trim, compact rich green leaves. The layered, lucent petals plus peppy green foundation create a fresh classic style that earns Snow Angel a front row seat in formal borders, as well as pollinator plantings, cottage gardens and even cut arrangements.

<i>Anemone hupehensis</i> ‘Crispa’

Reminiscent of triple curled parsley, the striking green leaves are embellished with curious curves, crinkles, ruffles and red-tinged margins. In autumn, 2 ft. tall stalks present delicate, 3 in. wide pale pink flowers, centered by shaggy yellow eyes, above an ultra-textured mound, which is more compact and less spreading than other hupehensis cultivars. Though there’s some confusion about its origins, this unusual British selection may be ‘Lady Gilmour’, an age-old cultivar first recorded in 1895.

Size: 20" – 2' 0" high x 2' 0" wide.

Hardy to zone 4.

<i>Anemone</i> x <i>hybrida</i> ‘Alice’ <i>Anemone</i> x <i>hybrida</i> ‘Alice’

Unlike many Anemones, ‘Alice’ spreads slowly, growing into a clump 3 ft. across within 3 years. It is robust and upright with large leaves that outsize the foliage of most hybrida forms. In our garden, the semidouble soft pink flow­ers appear to float against a hedge of Carpinus and contrast well with the yellow fall foliage of Amsonia hubrichtii.

<i>Anemone</i> x <i>hybrida</i> ‘Andrea Atkinson’

For vivacious color, try it with Phlox ‘Blue Paradise’, Tricyrtis or blue-flowering Gera­niums.

Blooms August–late October

Hardy to zone 5.

<i>Anemone</i> x <i>lesseri</i>

This lovely jewel-box-like hybrid affords cupped carmine-red blooms, festooned with spry yellow anthers above an attractive non-aggressive bed of low growing ferny green foliage. Parented by Anemone multifida and Anemone sylvestris, Anemone x lesseri’s fine cut palmately lobed leaves and uniquely colored up-facing flowers make compelling additions to the rockery, an open woodland planting or a border’s front lines. Appreciative of morning light accompanied by dappled afternoon shade on hot days, its dwarf habit requires minimal care, resists those meddlesome deer and prospers in moist well-drained organic-rich soil.

<i>Anemone multifida</i> ‘Annabella White’

A low-laying ferny mound of finespun green foliage and firm, somewhat fuzzy, upright stems lift the enchanting cupped white blooms. Selected from the North American native Anemone, ‘Annabella White’ keeps our interest sparked as abundant seed heads appear looking a bit like unripe strawberries, then later morph into a fluffy dove-gray mop. This compact undemanding perennial lends lovely accents to the rockery, a cottage garden, alpine planting or naturalized meadow, where it thwarts deer, looks most effective en masse and enjoys average well-drained soil with adequate moisture.

Blooms May–June

Size: 10" – 20" high x 10" – 12" wide.

Hardy to zone 3.

Adored by all who behold it, this charming European woodland plant boasts the choicest double Wood Anemone flowers in cultivation. Six ray petals, pure as the driven snow, encompass a fluffy white central tuft of distinctively gathered petaloid stamens.

Blooms late March–early May.

Size: 4" high x 12" wide.

Hardy to zone 4.

Brilliant citrine-yellow petals swirl around golden stamens, their sunny coloration rare for an Anemone. Often tinged red on the outside, the good-sized, saucer-shaped flowers are presented on slender, leafless 6 in. stems above a handsome basal mat of glossy deep green foliage. A southwest European native, this spreading Anemone prefers a sunny, well drained bank where its cheerful blooms can be paired with blue flowering Nepeta reichenbachiana.

Blooms May–June.

Size: 12" high x 8" wide.

Hardy to zone 6.

Native to the far reaches of Himalaya, India and Ceylon, this Anemone quickly emerges in the spring as an attractive basal clump of long-petioled deep green trilobed leaves. Red-tinged stems–silky, stiff, arching and branched–deliver snow white droves of large, open saucer-shaped flowers. Violet-blue anthers and backsides with dusty green and gun-metal blue streaks enhance the exquisite blooms, while spiky green seed heads gathered in ornamental clusters provide autumn allure. Unparalleled in drifts, ‘Glacier’ insists on cool, moist humus-rich soil.

Blooms June–August.

Size: 16" – 20" high x 12" wide.

Hardy to zone 4.

<i>Anemone</i> ‘Ruffled Swan’ <i>Anemone</i> ‘Ruffled Swan’

Hats off to the highly acclaimed Scottish Elizabeth MacGregor Nursery for this exceptional hybrida and rupicola cross.

With Old World appeal, its sweet smelling bounty of yellow-eyed, satiny white blossoms has been lighting up gardens for over 400 years. Atop straight 18 in. stems, delicate cup-shaped single flowers offer a repeat bloom come fall, and later develop ornamental cotton-like seed heads. Deeply cut, palmate green leaves form a lustrous dense ground cover that easily naturalizes in loamy soil and bright shade. Amenable to full sun where its cool and full shade where it’s warm, this ethereal beauty detests desert heat, can accompany early-flowering spring bulbs and may periodically need its energetic rhizomes curbed.

Imparting a strong sculptural presence, these selections are 3-year biennials that thrive in moderately moist well-drained spots. If you cut the blooms before the seed sets, you might be rewarded with flowers for 3 or even 4 years.

<i>Angelica archangelica</i>

The floriferous namesake of St. Michael the Archangel, who is supposed to have revealed its power to battle the plague, Angelica archangelica’s luxuriant, tropical-looking foliage makes a dramatic entrance each spring as leaves unfurl to a length of 2 to 3 ft. Flower buds of mauve, strikingly set against its deeply divided bright green verdure, herald the imposing lime-tinted white flowers surmounting thick, erect stalks. This Angelica’s aromatic young shoots have long been used as a flavoring in sweet confections.

<i>Angelica pachycarpa</i> <i>Angelica pachycarpa</i>

The sizable rounded mound of this Angelica‘s lustrous dark green foliage looks like a parsley plant on steroids. Endemic to New Zealand, its copious deeply fingered leaves offer handsome deer resistant support to the fanciful and fragrant snowy umbels that crown strong stalks. Growing as an undemanding somewhat short-lived perennial, but offering up seedlings as a consolation, Angelica pachycarpa‘s bold leaves bring fantastic architecture to a good-sized con- tainer or the border, especially when grouped with Actaea, ‘Brunette’ or Anthriscus ‘Ravenswing’.

Blooms April–June

Size: 3' 0" high x 3' 0" wide.

Hardy to zone 5.

While the species traipses throughout Europe and Eurasia’s roadsides, meadows and riverbanks, this impressive, yet slightly shorter cultivar can be invited into the moist loamy corners of your garden. The enormous pale pink umbels surmount towering, straight, dark reddish purple stalks and pinnate maroon-infused leaves sporting sawtooth-serrated margins. A mainstay for flower arrangers, honeybees and garden visitors,‘Vicar’s Mead’s robust biennial profile is exemplary for the back of the border where it lends bold yet lacy accents, plus readily reseeds.
