Veronica

Speedwell

According to legend, Saint Veronica used her handkerchief to soothe Christ’s brow, and forever after, it bore markings that are supposedly replicated in these long blooming Speedwell flowers. Flourishing in sunny, well drained sites, our Veronica selections are undemanding, and deliver dazzling color to the summer border.

Veronica incana ‘Pure Silver’ (P-1861)

Each $8.00

AVAILABLE SPRING 2021

Bees, butterflies and plant lovers arrive in droves to enjoy the tapering frosty tipped spires of tight-knit, vivid blue-violet flowers carried on branched leafy stems. Looking a bit like a Sage, the slender, toothed lance-shaped leaves create a tasteful, compact cool silver mass that is more tolerant of hot humid summers than other incana. An ideal low growing candidate for sharp-draining borders, pathway edging, walls or rock gardens, "Pure Silver" enhances companions such as Potentilla "Apricot Whisper" and Agastache "Firebird".

Blooms June–July

Size: 12" – 2' 0" high x 8" – 12" wide.

Hardy to zone 4.

Strong erect stems elevate a refreshing floral display of tall, slender pure white columns crowded with small tubular blossoms that taper into curvy green tips. Beloved by bees, butterflies and flower arrangers, the sophisticated spires bloom for several months, and last in a vase for 7 to 10 days. This clump-forming hardy perennial dons toothed and pointed, lance-shaped leaves, lending a lush green presence to the rockery or mixed border, especially when planted in eye-catching drifts.

Blooms June – August.

Size: 3' 0" high x 15" wide.

Hardy to zone 4.

Recently awarded a bronze medal by the Boskoop Horticultural Society, this vibrant new introduction comes to our country courtesy of the acclaimed Dutch nursery, Rijnbeek. Slender toothed green leaves, which are less prone than most Veronica to mildew and leaf spot, compose a tidy basal bed beneath plentiful dark blue spires. The plump electric-hued inflorescences seem to glitter as fanciful looking, long light-colored stamens unfurl, setting ‘Marietta’ apart from its Veronica longifolia cousins.

Blooms June-July

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

Hardy to zone 4.

All the way from Asia Minor’s sunny Mediterranean haunts comes this irresistible yet hard working evergreen ground cover. Offering up hordes of endearing bright blue, white-eyed blooms over a long period, this prostate Speedwell crafts a gray-green, matting carpet defined by light hairy stems and fuzzy deep cut foliage that looks a bit like miniature oak leaves.

Veronica pectinata is tailor-made for softening steps, rock walls or a path’s edge and is a cinch to grow, requiring only minimal water and a well drained nook.

Blooms July–mid-September.

Size: 2' 0" – 4' 0" high x 12" – 15" wide.

Hardy to zone 4.

With vibrant blue-violet flower spires, a well-groomed low growing appearance and exceptional cold hardiness, this hard-to-find reliable Siberian beauty captivates gardeners and butterflies alike. A slowly creeping dense mat of compact, somewhat round-tipped and widely toothed forest green leaves supports electrifying blooms all summer long and makes a resilient nofuss contender for a well-drained rockery, pathway or trough garden.

Blooms June–September.

Size: 8" – 12" high x 12" wide.

Hardy to zone 3.

Plentiful and sumptuously colored, the dense, dark violet-blue tapers crown a compact, noninvasive base of glossy deep green foliage that stays fresh well into fall. Show off this perky new British cultivar right up front with Achillea ‘Marmalade’s cheerful yellow flowers.

Blooms June–July.

Size: 15" – 18" high x 18" wide.

Hardy to zone 4.

A hybrid between Veronica armena and Veronica pectinata, this stellar weed-suppressing evergreen ground cover was introduced in 2007 by Dr. Jim Ault from the Chicago Botanical Garden. ‘Tidal Pool’ touts its parents’ finest traits plus exhibits a more close-knit, faster-to-spread prostate habit that’s festooned with oodles of small, white-eyed, vivid blue-violet blossoms. Acquiescent to cold, heat, humidity and dry conditions, the petite, slightly pubescent oak-shaped green leaves are dusted with blue and emphasize versatile good looks for nuzzling against steps or rocks, edging pathways, draping over walls and any other sunny, well-drained nook.

Blooms April–May

Size: 2' 0" – 4' 0" high x 2' 0" – 2-1/2' wide.

Hardy to zone 4.

Our Featured Plant: Crocosmia ‘Zeal Tan’

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.
