Sanguisorba

Burnet

A profusion of oblong, catkin-like blooms resides above decorative pinnate foliage, generating interest for months. Happiest in a sunny spot where the soil stays moist, these hearty perennials offer contrasting clarity to the softer, less defined forms in the naturalized garden or a border.

Casting strong vertical accents and captivating close-up details, this must-have new cultivar bears long, antique-toned rosy red bobbles studded with soft-looking black-tipped stamens. Handsome pairs of notched matte-green leaves loosely ascend the staunch, branching, red-tinged flower stalks. ‘Blackthorn’s splendid, upright cylindrical blossoms beckon butterflies and plant lovers alike, while its steadfast lusty habit can mingle with other late bloomers such as Persicaria ‘Taurus’ and Pennisetum ‘Karley Rose’.

Blooms July–October

Size: 5' 0" – 6' 0" high x 2' 0" – 2-1/2' wide.

Hardy to zone 4.

Collected in Yunnan, China by plantsman Dan Hinkley, ‘Cangshan Cranberry’ is a stately late-blooming cultivar whose daring bottlebrush-like flowers are suffused with marvelous dusky-burgundy hues. Inspiring British nursery proprietor Marina Christopher to coin the namesake, copious close-knit bobbles roost atop tall, slender, self-supporting reddish stems, while oval-shaped blue-green leaflets distinguish the winsome jagged-edged pinnate foliage. A dynamic counterpoint to blousey trusses and spires as well as daisy-style blooms, this lofty, seldom offered Sanguisorba can be peppered amid Phlox ‘Miss Mary’, Veronicastrum ‘Pink Glow’ and Helianthus salicifolia to great effect.

Blooms August–early November

Size: 5' 0" – 6' 0" high x 18" wide.

Hardy to zone 4.

<i>Sanguisorba hakusanensis</i>

Casting a fanciful feminine style all summer long, this gorgeous aptly named Japanese perennial premiers bushy purplish pink tails that gracefully arch downward on upright stems. A clumping base sprouts gray-green scalloped leaves, which showcase intriguing origami-like patterns as they unfurl and promise a long lasting well-groomed appearance.

Blooms July – August

Size: 18" – 2' 0" high x 15" wide.

Hardy to zone 4.

Fluffy, decidedly feminine and pendulous, the 5 in. long squirrel tail blooms are draped like bodacious pink boas atop sparsely leafed sturdy stems. Loose fine textured filaments define the look-at-me flowers, while red-infused petioles and bold blue-green pinnate leaves further enhance the beguilement.

Blooms July–September

Size: 20" – 2-1/2' high x 15" – 18" wide.

Hardy to zone 5.

<i>Sanguisorba menziesii</i> <i>Sanguisorba menziesii</i>

An assemblage of refined, feathery blue-green foliage gives way to slender branching stems and tightly arranged, finger-length blooms in vivid dark red shades. Earlier to flower than other Sanguisorbas, this enticing perennial cavorts with Nepeta ‘Wild Cat’ and Festuca mairei in our border.

Blooms May–July

Size: 2-3/4' high x 16" – 18" wide.

Hardy to zone 4.

Residing on wiry arching stems, soft pink fingerlike spikes look fluffy and feminine. They nod lazy heads at the handsome bushy mass of tranquil blue-green leaves marked by indented margins that grows below.

Hardy to zone 4.

Each $8.00

AVAILABLE SPRING 2021

<i>Sanguisorba officinalis</i>

Embodied with astringent properties, the Great Burnet’s handsome foliage can soothe not only inflamed skin but your senses as well. The vigorous rounded clump is an airy cool green arrangement of deeply cut, toothed basal leaves that promotes a relaxed presence in the landscape. Come summer, the mood changes when thin, tall branching stems lift tightly set, blood-red bottlebrushes. Create a fervor, plant en masse and savor the alluring color and shape of the flowers that dramatically offset Seseli gummiferum’s white umbels.

Blooms July–October

Size: 3' 0" – 4' 0" high x 2' 0" wide.

Hardy to zone 4.

Sanguisorba officinalis ‘Chocolate Tip’ (P-1786)

Each $8.75

AVAILABLE LATE SEPTEMBER 2020

<i>Sanguisorba officinalis</i> ‘Chocolate Tip’

Famed for its ferny blue-green foliage that’s burnished with chocolate overtones, this superb new cultivar produces a lavish plethora of egg-shaped brunette-tinged maroon flowers. The dense chubby blooms uniquely open from the bottom up, while perched on firm slender branching stems. ‘Chocolate Tip’ brings a buoyant stance and dark saturated hues to the colorful blooms of Agastache ‘Bolero’ and Aster ‘Harrington’s Pink’ in our border.

Blooms July–October.

Size: 2-1/4' high x 16" wide.

Hardy to zone 4.

Sanguisorba officinalis ‘Crimson Queen’ (P-2071)

Each $9.75

AVAILABLE LATE SEPTEMBER 2020

Close-set, long-lasting and early to unfurl, myriad egg-shaped Merlot-hued blooms adorn a sprightly array of wire-thin branching stalks. This striking new cultivar sprouts decorative toothed bluish green leaves, crafting an enduring, no-quibble basal mound that’s ideal for borders, cutting gardens or meadow-style plantings.

Blooms July–September

Size: 3-1/3' high x 18" – 2' 0" wide.

Hardy to zone 4.

Derived from a Korean collection of Sanguisorba officinalis, this snazzy Sanguisorba was selected by Dutch plantsman Piet Oudolf for its deep ruby-red bobbles, perched on tall stiffer stems. Whether in the border or a meadow planting, a vase or frost covered in the garden’s winter light, their distinctive silhouette inspires as much drama as a gathering thunder head. A green bed of pinnate foliage with toothed leaflets launches the strong floral display that can be superimposed against lofty silver-plumed Miscanthus, whorled Veronicastrum blooms and Helianthus ‘Capenoch Star’.

Blooms July–October

Size: 3' 0" – 4' 0" high x 2' 0" wide.

Hardy to zone 4.

<i>Sanguisorba officinalis</i> ‘Tanna’

Well suited for the smaller scale garden, ‘Tanna’s mound of ferny leaf fronds makes an elegant host to the cylindrical, burgundy flower spires that playfully top foot-long stems. Cultivated since the Middle Ages, the cucumber-flavored foliage has been a welcome addition in the salad bowl.

Blooms July–August.

Size: 18" high x 12" wide.

Hardy to zone 4.

A ‘see-through’ plethora of dense, muted pink catkins with pale rose-colored stamens alight sturdy, erect branching stems above a decorative, grass-green basal clump. Beloved by butterflies, the spry, furry blooms turn a warm russet-brown as they age, while close-set, toothed pinnate foliage offers bright canary-yellow hues for autumn. Adaptable to clay soil and larger than the more well-known ‘Tanna’, this durable perennial’s easy-to-blend, long-lasting blooms can be massed near the front of the border or in a less formal venue.

Blooms July–September

Size: 18" – 2' 0" high x 18" wide.

Hardy to zone 4.

A textural delight of saw-toothed, finely divided leaves, ‘Alba’s clump-forming mound lays the foundation for slim, fluffy white, drooping blooms. The elegant cylindrical flowers are abundantly borne on tall branching stems, well above the energetic greenery, and look like luminous catkins caught in a rain shower.

Blooms September–October

Size: 4' 0" – 5' 0" high x 18" wide.

Hardy to zone 4.

You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes. 

All of us Digging Dog plant wranglers wish you Happy Digging and good health.
