Pulmonaria

Pulmonaria

Lungwort

One of the earliest plants to bloom, you can be picking Lungwort’s urn-shaped flowers in February while the rest of the garden still slumbers. Easy-to-grow Pulmonarias prefer the lacy light of a woodland setting and cool moist soil. They are excellent noninvasive ground covers.

Lance-shaped dark green leaves create a handsome solid-colored bed for nodding clusters of vivid cobalt blue funnel-shaped flowers atop short stalks. Granted a four star score at the Chicago Botanic Garden’s Pulmonaria trials, ‘Blaues Meer’s vigorous enduring clump makes a verdant statement beneath Spiraea ‘Ogon’.

Blooms February-April

Size: 8" – 10" high x 18" wide.

Hardy to zone 4.

Here’s one type of frost that should be welcomed into gardens with open arms. The mildew resistant foliage of this compact species has a green midrib and is irregularly splashed with so much silver that there is often more silver than apple green. Such “frost” complements the soft rose-colored flowers, which fade to violet-blue. The Maple-like foliage of Kirengeshoma palmata makes it an interesting neighbor for ‘Apple Frost’.

Blooms March–April.

Size: 12" high x 18" wide.

Hardy to zone 4.

<i>Pulmonaria</i> ‘Benediction’

The lush foliage of ‘Benediction’, with its widely spaced silver spots, ranks above that of other dark green-leafed Pulmonarias. A favorite for massing, we especially enjoy the profusion of deep blue flowers when planted next to Epimedium x rubrum and Euphorbia ‘Great Dixter’.

Blooms early March–May.

Size: 10" high x 18" wide.

Hardy to zone 4.

<i>Pulmonaria</i> ‘Berries and Cream’

The raspberry-pink flower of this species is a new color for Pulmonarias. Against the sparkling, mostly silver leaves with slightly ruffled, mottled green margins, the flowers are as enticing as a bowl of fresh berries and cream. Plant in large drifts and watch the flowers—and your garden—turn purple with age.

Blooms March–April.

Size: 12" high x 18" wide.

Hardy to zone 4.

Spotted by highly regarded British plant maven Bob Brown and named in honor of his wife, this robust P. longifolia hybrid is hailed as one of the best silver-leafed Pulmonaria for hot locales. Dashing, long pointed leaves are initially rimmed with a stippled pewter and green border, which quickly morphs into solid sterling silver. A classy early spring charmer, ‘Diana Clare’s well-tailored clump cushions plentiful, perky dark violet blooms, aging to cobalt-blue on short sturdy stalks.

Blooms late February–April

Size: 10" high x 12" – 18" wide.

Hardy to zone 4.

<i>Pulmonaria</i> ‘Excalibur’

With a metallic effulgence that’s reminiscent of mercury, this Pulmonaria is a refined inspiration for the darker corners of your garden. Its lance-shaped leaves are completely frosted in silver except for a pencil-thin, deep green edge. Impressively mildew resistant, ‘Excalibur’s striking foliage is graced by charming rosy pink and blue flowers long before spring’s treasure trove of bloom gets underway. (pp#8958).

Blooms March–May.

Size: 10" high x 20" wide.

Hardy to zone 4.

With foliage that’s more diminutive than other Pulmonarias, this compact Lungwort can easily squeeze into an intimate space. While the deep cobalt blue of the flowers fades to a softer purple, the distinct silver spots of the narrow leaves remain intense and dazzling. We let ‘Little Star’ skirt the ground beneath the gilded foliage of Clematis ‘Stolwijk Gold’ for a dramatic foliar contrast.

Blooms early March – April.

Size: 8" high x 12" wide.

Hardy to zone 4.

<i>Pulmonaria longifolia</i> ssp. <i>cevennensis</i>

This marvelous subspecies from the Cevennes region of France will perk up any shady spot with its slender, silver mottled leaves that are spear-shaped and distinctively large, reaching up to 2 ft. in length. Wider than most longifolia species, good-sized cobalt blue flowers fade to violet atop a mounding, highly mildew resistant base.

Blooms March – April.

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

Hardy to zone 4.

A beloved older cultivar named for a noted British plantsman, this boldly marked Pulmonaria boasts a dashing mound of steel splotched, long narrow dark green leaves and clustered bright cobalt blue blooms. Its distinctive good looks, abundant full-toned flowers and easily maintained habit earned 'Bertram Anderson' a perfect score at the Chicago Botanic Garden's Pulmonaria Trails and should give you plenty of reason to welcome him into your favorite shady nook.

Blooms February–April.

Size: 10" high x 12" wide.

Hardy to zone 4.

Solidly sheened with silver, ‘Majesté’s thick leafage is extremely elegant—even without any flowers. But in early spring, short arching sprays of both blue and pink blooms make an appearance and, against the leaves, it’s a color-rich delight. Omphalodes ‘Cherry Ingram’s greenery offers a vivid contrast.

Blooms March–April.

Size: 12" high x 15" wide.

Hardy to zone 4.

<i>Pulmonaria</i> ‘Opal’

Good-sized dark green ovate foliage, heavily tattooed with irregular slate-colored blotches, patches and spots, lolls beneath a delicate presentation of funnel-shaped pale ice blue blooms on short stems. ‘Opal’s cool composed visage can be sited amid wild gingers and backed by Anemone leveillei.

Blooms March–May

Size: 6" – 12" high x 6" – 18" wide.

Hardy to zone 4.

<i>Pulmonaria</i> ‘Roy Davidson’ <i>Pulmonaria</i> ‘Roy Davidson’

This prized Pulmonaria’s periwinkle blue flowers stand 6 to 8 proud inches above handsome, evenly silver-blotched foliage. Broad, Hosta-like green leaves are slightly rough to the touch. It works well as a ground cover in a shaded rock garden and blooms for an exceptionally long time.

Blooms mid-February–May.

Size: 12" high x 18" wide.

Hardy to zone 4.

Awarded 4 stars at the Chicago Botanic Garden's Pulmonaria Trails, 'Dora Bielefeld' delivers pretty rose pink funnel-shaped flowers atop a consistently well-groomed apple green mound with wide-spaced pearly speckles and plenty of hearty gusto. Her decidedly feminine blooms seldom fade to purple and make a lovely addition to companions such as Helleborus 'Picotee Lady' and Aruncus aethusifolius.

Blooms February–April.

Size: 12" – 15" high x 15" wide.

Hardy to zone 4.

<i>Pulmonaria saccharata</i> ‘Highdown’

A friend in Montana tells his wife every night that what she’s cooking for dinner is his favorite, and he means it. We’re like that with Pulmonarias. This one is our favorite too—for its flower. It’s the truest, the showiest, the brightest blue, and the earliest to bloom. Large, richly green foliage is dappled in swank grays and silvers.

Blooms February–April.

Size: 12" high x 18" wide.

Hardy to zone 4.

<i>Pulmonaria saccharata</i> ‘Sissinghurst White’

Pristine, soft white flowers crown mercury-dappled and freckled deep green leaves that are broader than other saccharata species. Resembling ‘Roy Davidson’ in terms of spotted foliage, this Pulmonaria is more open, bearing its flowers more loosely and later in the spring.

Blooms February|ndash;April

Size: 10" high x 12" wide.

Hardy to zone 4.

Ruffle-edged, mercury-hued and randomly dappled with green, the spectacular long slender leaves grow upward then gracefully arch downward. A Dan Heims hybrid between Pulmonaria . ‘Redstart’ and Pulmonaria . ‘Excalibur’, this posh steadfast shade dweller debuts colorful clusters of dainty drooping funnel-shaped blooms, which open pink, then turn blue, perched atop short stems.

Blooms March–April

Size: 12" high x 18" wide.

Hardy to zone 4.

A winning Terra Nova introduction between Pulmonaria longifolia ‘Bertram Anderson’ and Pulmonaria vallarsae ‘Margery Fish’, this energetic Pulmonaria serves generous portions of clustered, large royal-blue flowers. The princely deer and mildew-resistant mound is defined by lance-shaped green foliage peppered with plentiful silver spots. Exhibiting good heat and humidity tolerance, ‘Trevi Fountain’ is a superb choice for Southern gardens as well as other woodland settings throughout the country. (pp#13,047)

Blooms March|ndash;April

Size: 12" high x 18" – 2' 0" wide.

Hardy to zone 4.

Our featured plant: Crocosmia x crocosmiiflora ‘Honey Angels’

Colorful Crocosmias, Be Awed by your August garden, Saturday Strolls!

Colorful Crocosmias!

Crocosmias pack a punch of late summer color as our gardens transition into autumn. Their clustered tubular flowers populate the ends of gracefully arching spikes, which emerge from handsome sword-like foliage. Ranging from yellow, peach and orange to fiery red, their prismatic shades look exceptional with white flowering perennials such as Phlox ‘David’, Selinum wallichianum and Aster ‘Bridal Veil’, as well as the blue blossoms of Aconitum, Agapanthus ‘Storm Cloud’ or Aster ‘Twilight’. For fun you could create a hot border, blending them with Kniphofia, Helenium, Salvia and even other Crocosmia, plus be sure to include some in your next bouquet. Commonly referred to as Montbretia and hardy to Zone 6, they appreciate, good drainage, adequate water and some shade in scorching summer sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

YES, it’s possible to be in awe of your late August garden….

At this point in the season, some areas in our gardens may appear a tad worn or lackluster. If you haven’t already done so, you may wish to cut back a few tired looking perennials, such as the Nepetas or Geraniums, so you can enjoy a fresh flourish of growth plus more blooms. Adequate moisture and an additional application of compost will also ensure late summer vigor. Incorporating plants that provide a bounty of flowers and alluring leaves in August and September helps buoy our spirits, and hopefully even inspire a little awe as we approach fall. Though the plants featured in this newsletter either promote a bold statement or possess more refined aspects, they equally caught my eye and made me pause to take a closer look. Perhaps they’ll spark a wondrous moment for you as well. All of us Digging Dog plant wranglers wish you Happy Digging!
