Veronicastrum

Culver's Root

These elegant perennials impart a lofty vertical element to the late summer garden. Graced with distinctive narrow spires of densely arranged tiny flowers, Veronicastrum are native to meadows and woodlands, and are easy to grow in adequately moist soil.

Studded with lavender blue blooms, the lengthy flower spikes make an elegant presentation. Arranged in groups, they stand proudly on upright, sturdy stems, which sport spaced whorls of neat, broadly lanceolate leaves. This noble Asian native offers an admirable contrast to mounding forms, such as Amsonia hubrichtii.

Blooms July–September.

Size: 5' 0" high x 18" wide.

Hardy to zone 4.

<i>Veronicastrum sibiricum</i> ‘Red Arrows’

True to its name, this distinctive undemanding Coen Jansen introduction asserts deep rosy red buds squeezed onto a central spike, surrounded by slightly smaller side stalks all opening at the same time and presenting a unique arrow shape. Cherished by bees and butterflies, the striking spires unfurl a multitude of tiny violet flowers, while whorled lanceolate leaves attire tall steadfast stems. A glamourous upright mainstay for any planting, 'Red Arrows' soars amongst Trifolium rubens, Phlomis 'Amazon' and Sedum 'Matrona' in a prairie-style landscape or a more formal setting.

Blooms July – September.

Size: 4' 0" high x 18" wide.

Hardy to zone 4.

In addition to the stylish blooms, this sought-after Veronicastrum gives you good reason to adore it. When tall valiant stems stretch skyward, they strut prismatic purple shades that are easily spotted from a distance, promising to turn more than a few heads. Round, dense pink buds set the stage for ethereal-looking lilac flowers on candelabra-like spires, further enhancing the dashing whorls of pointed deep green leaves.

Blooms August – September

Size: 4' 0" – 5' 0" high x 2' 0" wide.

Hardy to zone 4.

<i>Veronicastrum virginicum</i> ‘Album’

Resembling glowing tapers, erect snowy white racemes tipped with green buds make a crisp, classic statement. The luminous blooms hold court above whorls of horizontally set deep green foliage that grow at intervals along sturdy upstanding stems. Veronicastrum ‘Album’ commands our attention, while it sheds light on cohorts such as Geranium ‘Jolly Bee’ or Helianthus ‘Capenoch Star’.

Blooms August – October.

Size: 4' 0" high x 15" wide.

Hardy to zone 4.

‘Apollo’s leafy stems taper delicately into foot-long lilac racemes tipped with vivid green buds, which bend and curve, adding a playful air to its imposing carriage. Display graceful ‘Apollo’ with Angelica archangelica’s rounded umbels, and the rosy plumes of Miscanthus ‘Nippon’.

Blooms August – September.

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

Hardy to zone 4.

‘Erica’s staunch leafy stems taper delicately into long 2-toned racemes of reddish buds and small tightly packed pale pink flowers with prominent darker stamens. Opening from the base up, the slender wands bend and curve, adding a playful air to the impressive carriage below. Display this graceful Veronicastrum with Angelica ‘Vicar’s Mead’ rounded umbels and the wine-red blades of Panicum ‘Ruby Ribbons’.

Blooms July–September

Size: 3' 0" – 4' 0" high x 15" wide.

Hardy to zone 4.

‘Fascination’s leafy stems taper delicately into 15 in. long lilac-rose racemes tipped with vivid green buds, which bend and curve, adding a playful air to its imposing carriage. Display this graceful Veronicastrum with Angelica archangelica’s rounded umbels, and the rosy plumes of Miscanthus ‘Nippon’.

Blooms August–September.

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

Hardy to zone 4.

<i>Veronicastrum virginicum</i> ‘Lavendelturm’

Coined Lavender Towers, this imposing Ernest Pagels introduction is aptly named. Straight-up stems garbed in handsome greenery—whorled, sharply toothed and pointed—give way to long branched spikes embellished with lovely pale purple flowers.

Blooms August – September.

Size: 4' 0" – 5' 0" high x 2' 0" wide.

Hardy to zone 4.

Exceptional Echinops, Plants to freshen up your August garden, Saturday Strolls!

Exceptional Echinops!

The striking floral orbs sport either frosty white, cobalt blue or metallic-blue shades, while perched atop sturdy erect stems with handsome jagged-edged foliage. Cherished by pollinators, floral designers and gardeners alike, Echinops thrive in sunny, well-drained niches, though are tolerant of poor soil as well as rock-strewn or sandy sites. These undemanding European natives are perfect candidates for a formal border, cottage garden, meadow-style planting or a cut arrangement. Be sure to check out our online Echinops offerings.

Cool colors for your summer plantings….

Icy white, pale pink and chartruese shades perk up our August borders, while effortlessly blending with just about any color imaginable. These composed hues provide our eyes with bright, yet soothing focal points and an overall beat-the-heat ambience! Some of our cool-down favorites include: Echinops, Sidalcea ‘Elsie Heugh’  Euphorbia mellifera, Kniphofia ‘Green Jade’, Phlox ‘David’ and Tanacetum ‘Isla Gold’. I’ve also featured a handful of richer-toned flowers that I discovered on my early morning walk today. We hope you’ll try sprinkling a few of these perennials amid your landscapes and enjoy both their tranquil or more spirited effects.

Happy August and Happy Digging from all of us Digging Dog plant wranglers!
