Verbena

Vervain

Our noteworthy offerings from this diverse genus feature captivating cool-colored summer-time flowers, coarsely toothed hairy foliage and tall 4-angled stems. Easily grown in average garden soil, they will delight you with months of bloom and a lighthearted presence.

<i>Verbena bonariensis</i>

A celebrated perennial whose fans include both experienced gardeners and novices, plus florists and hummingbirds, this versatile South American native delivers outstanding flower-power. Rough, lance-shaped dark green basal foliage gives way to wiry and sparsely leafed angular-branching stems, which elevate a consortium of tiny lavender-violet blooms. With fragrant flowers borne in dense tufts atop its airy profile, Brazilian Vervain brings a colorful carefree look to cottage gardens or more wild venues, especially when sprinkled amid ornamental grasses.

Blooms June – October

Size: 3' 0" – 6' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 7.

This vigorous North American native grows upright and develops a dense, broad crown after a few seasons. The effect is almost candelabralike, with tiny blue-violet flowers and purple bracts opening in an upward-moving whorl along branching flower spikes. The vibrant glow of the flowers reflects the deep purple stems and brightens the dark green pointed foliage. For an interesting blend of forms, plant this Vervain with Rodgersias and Helianthus hirsutus.

Blooms July–September.

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

Hardy to zone 4.

This vigorous North American native grows upright, developing a dense, broad crown after a few seasons. The effect is almost candelabra-like, with tiny blue-violet blooms and deep purple bracts opening in an upward-moving whorl along branching flower spikes. The vibrant bicolored glow of the blossoms reflects the deep purple stems and brightens the pointed dark green opposite foliage.

For an arresting blend of forms, plant this Vervain with Helianthus ‘Gold Lace’ and Sesleria ‘Greenlee’.

Blooms June – October.

Size: 3' 0" – 4' 0" high x 18" – 2' 0" wide.

Hardy to zone 4.

Verbena hastata ‘Pink Spires’ (P-1779)

Each $8.00

AVAILABLE FALL 2019

Vividly colored flowers and darker pink buds are housed on well-branched slender spires of small pink blooms opening from the bottom up. The pretty floral parade rides straight-backed, tall steadfast stems clothed in opposite, pointy dark green lax leaves, creating a dynamic juxtaposition between the untaut foliage and the plant’s stiff upright stature. ‘Pink Spires’ promises nonstop blooms all summer long, injects height into your border, never needs staking and makes a stellar cut flower.

Blooms June–October.

Size: 3' 0" – 4' 0" high x 18" – 2' 0" wide.

Hardy to zone 4.

Perched on stiff tribranched candelabra-style stems, small dense clusters of electric purple flowers work tirelessly from late spring ’til early autumn, delighting pollinators and plant enthusiasts. Attractive rough-surfaced dark greenery—oblong and toothed—loosely cloaks the upright bushy habit that endures heat, drought and most pests. A somewhat tender, low growing perennial, ‘Santos’ craves sun and good drainage, fits easily into smaller gardens or containers plus makes a dazzling companion for Dahlia ‘Bishop of Llandaff’ and Crocosmia ‘John Boots’.

Blooms June–mid-October

Size: 18" – 2' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 7.

Our Featured Plant: Crambe cordifolia

Compelling Crambes!


A study in Paleolithic proportions and high drama, this Cruciferous family member is a sturdy long-lived perennial. Large, coarsely toothed crisp green leaves launch a hefty multi-branched pale green stem, which bolsters an enormous Gypsophila-style cloud of tiny 4-petaled white flowers. Crambe can be utilized as a backdrop or a bold specimen mid-border, plus makes a stunning addition to cut arrangements, fresh or dried. It craves a sunny spot with well-drained average garden soil.

Usher in Summer with June Blooms!


June is an exciting month in the garden. It is a time of transition, a changing of the guard, so to speak, as many early flowering perennials are beginning to fade, while the summer bloomers are taking center stage. I’ve included a handful of perennials, whose beckoning floral or foliar effects usher in summer! 

Happy digging and happy summer from all us Digging Dog Plant Wranglers!
