Verbascum

Verbascum

Mullein

This genus has a host of common names, including “Beggar’s Blanket” and “Old Man’s Flannel.” In England, the very poor used to put the thick leaves into their shoes for warmth. Although most of the more than 300 species are biennials, our offerings are predominately perennials. Though some are dwarfs and some are giants, nearly all have fuzzy stamens and prefer very well-drained sandy or rocky soil. We like to use them in the border or rock garden as specimens or en masse for a meadow-style planting.

Grounded by gray-green rosettes, these upstanding candelabras of copious, violet-eyed, sunshine-hued flowers stage a truly incandescent spectacle. Irregular scallops, net-veining and long petioles define its dynamic large basal leaves. Preferring a somewhat dry, well drained site, ‘Sixteen Candles’s proud yellow spires command attention alongside Nepeta reichenbachiana.

Blooms June–August.

Size: 3-1/4' high x 2' 0" wide.

Hardy to zone 5.

Luminous tapers unfurl droves of tightly set pure white flowers centered by fleecy purple filaments and bright orange anthers. The flat-faced blooms shine above wrinkled grayish green leaves. Conveying a bright floral lift all summer long, this undemanding perennial can be sited in drier garden areas with Achillea x schwellenberg and Eryngium "Blue Glitter".

Blooms June–August

Size: 3' 0" – 3-1/2' high x 18" wide.

Hardy to zone 5.

<i>Verbascum</i> ‘Clementine’

When British plant breeders, Vic Johnstone and Claire Wilson, developed more than a thousand hybrids utilizing various wild Verbascum species, they chose only the best dozen seedlings and dubbed them ‘The Riverside Hybrids’; this splendid toasty hued prodigy was one of them. Sprouting from handsome rippled green basal leaves, numerous, well-branched straight stems bolster burgundy flushed button-like buds on tall floral spikes.

Large and luscious, wide-open coppery orange flowers, festooned with a central cluster of woolly light violet filaments, lend warm vertical accents to Allium ‘Gladiator’.

Blooms July – August.

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

Hardy to zone 5.

<i>Verbascum</i> ‘Gainsborough’

This Verbascum’s hushed colors are soothing to the senses and easy to blend with other perennials. Centered by delicate orange stamens, the cupped, dusky primrose yellow flowers and cream-colored buds squeeze onto numerous branched candelabra-style spires. Downy gray leaves converge at the base of the statuesque presentation, while Echinops ‘Arctic Glow’s snow white spheres make a pleasing counterpoint.

Blooms July – August.

Size: 4' 0" – 4-1/2' high x 18" wide.

Hardy to zone 5.

A felted biennial rosette of ample, grayish green ripple-edged foliage unleashes spectacular 6 ft. tall luminous flowering stalks. The crowded, blunt-tipped stout stems house fuzzy, round silver buds and large saucer-shaped blossoms bathed in soft custard yellow hues with orange anthers. These long blooming, multibranched beauties are some of the last flowers to grace our mixed border, delivering glowing vertical accents ‘til October’s end.

Blooms July–October.

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

Hardy to zone 6.

<i>Verbascum nigrum</i> ‘Album’ <i>Verbascum nigrum</i> ‘Album’

With flower spikes reaching over 3-½ ft. tall, ‘Album’ is truly dramatic. Its many white flowers are tinged with crimson at the base of each petal and accented by golden orange stamens. The large basal leaves are coarse, deep green and textured. Their undulating margins, and often their stems, are tinted a deep burgundy color.

Blooms July–August.

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

Hardy to zone 5.

A remarkable perennial of Olympian proportions, Candlewick originates in Europe’s Bithynian Mountains. Large, felted, wavy-edged leaves form a huge, silvery basal rosette that lasts through the winter. In summer, woolly “candles” branch out at the base, and soar skyward with cheerful clusters of bright yellow flowers. Outstanding as a feature plant in a shrubby Mediterranean border, this monumental Mullein appreciates a dry spot.

Blooms July–September.

Size: 6' 0" – 8' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 7.

<i>Verbascum phoeniceum</i> ‘Flush of White’

Studded with yellow-eyed pure white blooms, slender flowering spikes herald a niveous display anchored by the tidy compact rosette of ripple-edged green foliage. ‘Flush of White’s uniform snowy coloration is unusual for a Verbascum, while its smaller stance becomes an added bonus where space is limited.

Blooms May

Size: 2' 0" – 2-1/2' high x 18" wide.

Hardy to zone 6.

<i>Verbascum phoeniceum</i> ‘Rosetta’

'Rosetta' puts on a colorful flower display, bejeweled in pretty carmine-pink hues. Anchored by comely, crimpled dark green leaves, the tall spires host sumptuously hued, gold-centered, saucer-shaped flowers that celebrate the vivid hues of Phygelius ‘New Sensation’ and Liatris ‘Floristan Violett’.

Blooms May–August.

Size: 2' 0" – 2-1/2' high x 18" wide.

Hardy to zone 6.

<i>Verbascum phoeniceum</i> ‘Violetta’

As a precursor to the royal floral show of this delicate Mullein, enchanting buds swell, resembling tiny, dark silk cushions. A deep green, flat rosette of oval-shaped, crinkled leaves provides an attractive foil for the airy and richly colored flowering spires. Illuminated by gilt stamens, papery purple blooms are flat-faced and look fabulous in arrangements. Self-seeding easily, and shorter in stature than many Verbascum species, ‘Violetta’ is perfect for more intimate spaces.

Blooms May–August

Size: 2' 0" – 3' 0" high x 18" wide.

Hardy to zone 6.

<i>Verbascum</i> ‘Pink Domino’

Romantic shades of rose-pink and salmon dress up these dark-eyed saucer-shaped blooms. Standing straight and tall, the lovely spikes rise from a rich green, purple-streaked, ripply rosette. Sprinkle among Monarda ‘Purple Rooster’ and Eryngium ‘Big Blue’ for divergent flower forms and an unrivaled feminine touch.

Blooms June – August

Size: 4' 0" – 4-1/2' high x 18" wide.

Hardy to zone 5.

A stately stand of tall branched racemes laden with large, cupped white blooms distinguishes this new Verbascum cultivar. Fuzzy basal foliage, steeped in soft smoky greens, launches the sparkling display that shows a lively splash of color when reddish purple floral filaments appear.

Blooms June – August

Size: 3-1/4' – 4' 0" high x 18" wide.

Hardy to zone 5.

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!
