Penstemon

Beard Tongue

Among the most exuberantly blooming plants this side of the Mississippi, Penstemon is part of the enchantment of the West. A member of the Snapdragon family, even cultivated varieties retain a natural air, with dainty, long trumpet flowers and five (pent) prominent stamens.

Sturdy and easily grown, species vary from 1 to 5 ft. tall, and range in color from white to pink to purple to deep wine redone for every sunny spot. Trim after the first bloom to encourage a repeat flowering, and cut to the crown in winter for bushy growth next season.

<i>Penstemon</i> ‘Stapleford Gem’

Earning the prestigious RHS 1993 Garden Merit Award, this outstanding Penstemon’s large, delicately colored trumpets seems to shimmer with hushed violet-blue-hued petals and paler, purple striated white lower lips and throats. Waxy green, lance-shaped leaves densely cloak the robust lush-looking foundation while wine-red stems add warm accents.

Blooms June – September.

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

Hardy to zone 6.

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!
