Diascia

TwinSpur

These increasingly popular South African perennials are good-looking, vigorous and quick to fill out. The long blooming cloud of pink to peach to lavender-colored flowers make these gracefully spreading plants perfect for containers.

<i>Diascia</i> ‘Blackthorn Apricot’

The striking color of these good-sized flowers will remind you of delicious summer peaches. Held about 6 in. above the fine dense mat of dark green foliage, they blend beautifully with Nepeta ‘Kit Kat’ and Scutellaria ‘Moonbeam’. Take advantage of this cultivar’s vigorous growth in a rock garden or in the front of a border with Eucomis ‘Sparkling Burgundy’ and Salvia sinaloensis.

Blooms April–October.

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

Hardy to zone 8.

‘Blue Bonnet’ forms a compact mound of slender, dark green, glossy triangular foliage that gracefully softens the edge of our garden path. The unique blooms are quite painterly: pink infused with blue, like a watercolor portrait, and highlighted by a cluster of bright yellow stamens.

Blooms June–September.

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

Hardy to zone 8.

<i>Diascia</i> ‘Coral Belle’

Highly saturated coral pink spurred flowers, each adorned with a yellow spot on its upper petal, are held gracefully above a tidy mound of handsome broad leaves. For elegant contrast in foliage and form, pair with Schizostylis ‘Alba’.

Blooms May–mid-October.

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

Hardy to zone 8.

The pearly blooms of this recent British selection herald an exciting new color within the Twinspurs. Arising from close-knit, grayish green linear foliage, the wiry 18 in. stems display myriad flowers that open with pinkish hints, and soon pale to nearly white. Let ‘Blush’ colonize a well drained spot atop a stone wall, where its carefree stance brings charm to such plants as Dracocephalum ‘Fuji Blue’ and Antirrhinum sempervirens.

Blooms June – October.

Size: 18" high x 18" & spreading wide.

Hardy to zone 8.

An inspiring new breakthrough selection discovered in South Africa’s Drakensberg Mountains, this tough Plant Select introduction broadens the hardiness range of the genus, exhibiting exceptional tolerance to both hot and cold temperatures. From spring until frost, upright fine textured green foliage bolsters an abundance of coral-pink wands, brimming with luscious flowers enhanced by darker pink centers. A stalwart beauty that easily graces an array of sites, ‘Coral Canyon’ can be planted next to Kniphofia pauciflora and Phygelius ‘Moonraker’.

Blooms June|#8211;October

Size: 15" high x 18" wide.

Hardy to zone 5.

<i>Diascia integerrima</i> ‘Pink Adobe’

Evoking images of New Mexico’s plastered adobe walls, the uniquely colored, pale salmon pink flowers with maroon throats offer a head turning, nonstop display for months on end. Relaxed stems clad in needle-like green foliage form a tightset, deep green mound that is reliably cold hardy. Originating from a group of seedlings at High Country Gardens, this sturdy, small-sized gem appreciates a midsummer trim and rich garden soil.

Blooms June–October.

Size: 15" high x 18" wide.

Hardy to zone 5.

<i>Diascia</i> ‘Langthorn's Lavender’

Rosy purple masses of small comely blossoms and linear narrow green leaves set this low growing charmer apart from the more commonly known pink and apricot blooming Diascias. ‘Langthorn’s Lavender’s diminutive form can be tucked along the front of the border or into a crevice, where its perky summer-long floral parade, riding atop upright stems, makes a delightful color echo with the plumes of Astilbe c. ‘Pumila’.

Blooms June-October

Size: 8" – 12" high x 12" wide.

Hardy to zone 8.

Our featured plant: Crocosmia x crocosmiiflora ‘Honey Angels’

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!
