Trollius

Globeflower

Gracing gardens since the 16th century, these marvelous blooms inspired their name, which translates to “basin” in Latin or “globe” in German. Globeflowers are undemanding perennials that look best in drifts and are the perfect choice for the waters’ edge, a boggy spot or the border, granted a moisture-retentive, organic-rich soil and shelter from hot sun. A sterling addition to bouquets, the Buttercup-like blossoms surmount straight stems above handsome, deeply divided glossy leaves and promise a long summer fling with regular deadheading.

Reminiscent of Mother-of-Pearl or King Tuts alabaster vessels, the light creamy white color that imbues these large blooms brings a quiet refinement to the garden. Layered chiffon-like petals embellish stylish cup-shaped flowers, while below deeply chiseled, glabrous green foliage grows into an attractive, moisture-loving basal clump. Developed by George Arends over 60 years ago, this exquisite cultorum hybrid can be intermingled with the chartreuse sprays of Alchemilla mollis "Robusta".

Blooms early June–mid-July

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

<i>Trollius chinensis</i> ‘Golden Queen’ <i>Trollius chinensis</i> ‘Golden Queen’

Bearing a crown of 12 or more narrow vertical petals surrounded by an outer ring of cupped soft orange sepals, this Trollius is known as the Queen of the Buttercups. Lustrous dark green leaves serrated, toothed and finely cut meld a vigorous basal clump that launches the sturdy, 3 ft. tall flowering stems in no need of staking.

Blooms June–July

Size: 2-1/2' – 3' 0" high x 18" wide.

Hardy to zone 4.

<i>Trollius</i> x <i>x cultorum</i> ‘Cheddar’

Pale yellow, tissue-like petals fashion a chic, nearly double, shallow open cup. Casting a soft feminine mood, the sumptuous blooms pose above an attractive mound of shiny foliage carved into small sections. A Dutch introduction, ‘Cheddar’ deserves to find its way into more gardens, where it will flourish in damp open sites matched with companions such as Sanguisorba ‘Chocolate Tip’ or Geranium ‘Dark Reiter’.

Blooms June–July

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

Steeped in old-world allure, the gleaming flush of lusty deep green lobed foliage coronates large double lemon-yellow globes. A 1920s selection that shares lineage with Trollius europaeus, Trollius asiaticus and Trollius chinensis, this hybrids urbane silken flowers alight tall sleek stalks, flaunting showy stamens and a composed beauty. "Lemon Queen" demands cool moist soil and easily rules a woodlands edge with confidants such as Astilbe "Perkeo" and low growing Anemones.

Blooms June–July

Size: 2-1/4' high x 18" wide.

Hardy to zone 4.

Large creamy-yellow double blooms revel atop strong, straight leafy stems and deep-hewn toothed greenery that sports a shiny finish. This new, vastly improved cultivar arose from seed that Dutch nurseryman Coen Jansen sent to Jelitto Perennial Seeds in 2011 following his work with Trollius ‘Alabaster’, an old introduction from George Arends’ famed nursery. A friend to bees and floral designers, but not bunnies, ‘New Moon’s vigorous habit and posh Paeony-style flowers can be surrounded by Iris chrysographes ‘Black Form’ and Athyrium ‘Ghost’.

Blooms June–July

Size: 2' 0" high x 18" wide.

Zone 3/4.

Surviving the test of time, this cherished compact Trollius was first trialed at Britain’s Wisley Gardens around 1929. Poised on sturdy stems, large, dazzling yellowish orange blooms are bedecked with ornate central clusters of darker tangerine petals. ‘Orange Crest’s ebullient buttercup-like display and tasteful, deeply divided glabrous leaves crave morning sun and cool moist soil.

Blooms June–July

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

Distinguished by overlapping, incurved petals bathed in cool lemon-yellows, beautiful globes gracefully alight foot long olive-green stems. A polished foliar mass grounds the bounteous one to two in. blooms. Maintaining a fresh look even when exposed to drier conditions, the large richly green leaves are rounded and divided into 5 parts with each lobed leaflet emargined by prominent teeth.

Blooms June–July.

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

Captivating Crocosmias, Plants that Dodge to Dog Days of Summer, 2020 T-shirst have arrived!

Captivating Crocosmias!

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

Dodge the Dog Days of summer….

with plants that pack a punch of blooms and alluring leaves at this time of year. By late August, our borders can look a tad tired and may be in need of some sprucing up. Adequate moisture and an additional application of compost will ensure late summer vitality. 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.
