Philadelphus

Mock Orange

First introduced to Europe along with Lilacs by Ambassador Ogier Ghiselin de Busbecq in 1562, this classic and easy-to-grow hollow-branched shrub was used by the Turks to make pipes. Its Latin name means “brotherly love” and its orange blossom-like fragrance has enhanced teas, perfumes, and almost certainly, many friends’ walks in the garden.

A denizen of southern Europe and Asia Minor, this sublime, upright, medium-sized shrub steals the show as vibrant, oval-shaped gold leaves burst forth in spring. Citrus-scented, 2 in. wide, crisp white flowers bestow additional enticements, while the deciduous leaves adopt refreshing lime-green hues by midsummer. Acquiring a British AGM plus popularity among pollinators and gardener’s alike, ‘Aureus’s bushy glowing habit relishes a sunny abode with moderate water and protection from hot afternoon sun.

Blooms May–June

Size: 5' 0" – 6' 0" high x 4' 0" wide.

Hardy to zone 5.

<i>Philadelphus</i> ‘Innocence’

We like to inhale the intoxicating orange sweetness given up by these freely borne, pure white blossoms that openly welcome. Gathered at branch tips, the large 4-petaled flowers garnish ovate green leaves randomly splashed and streaked with creamy whites, yellows and golds. A courtly perfumed scene stealer, this 1900s Lemoine Nursery cross between Philadelphus microphyllus and Philadelphus coronarius matures into an imposing shrub with fluid, arching branches.

Blooms June

Size: 8' 0" – 10' 0" high x 8' 0" wide.

Hardy to zone 5.

<i>Philadelphus</i> x <i>x lemoinei</i> ‘Belle Etoile’

Its name conjures thoughts of beautiful stars (Belle Etoile). Brushed with maroon at the base of each of the four petals, the white flowers unfurl just when spring blooming shrubs are finishing their display. In close proximity to an entrance or walkway amid Luzula ‘Auslese’ and Geranium ‘Ingwersen’s Variety’, this graceful shrub is easy to grow, deliciously scented and unmistakably choice.

Blooms July–September

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

Hardy to zone 5.

Of all our selections, this one smells the sweetest. The elegant cream-colored double flowers are bowl-shaped and the green foliage remains glossy and crisp even under stress from heat and sun. Ours grows at the base of an apple tree,constantly tempting us to put aside work for awhile and linger in its scent.

Blooms August–October

Size: 5' 0" – 6' 0" high x 5' 0" – 6' 0" wide.

Hardy to zone 9.

<i>Philadelphus</i> ‘Snow Dwarf’

If space is a premium in your garden and you’re searching for an ambrosial delight, you may want to try this short-sized, winter-rugged Canadian beauty. Oval-shaped dark green leaves and upright arching stems craft a dense foil for the abundance of exquisite crisp white flowers. With its neat dwarf appearance and fragrant summer blossoms, ‘Snow Dwarf’ can be featured as a container specimen or positioned close to the frontlines.

Blooms May–June

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

Hardy to zone 4.

<i>Philadelphus</i> ‘Snowbelle’

Gorgeous terminal clusters of double snowy white blossoms ring in summer, filling the air with zesty citrus aromas. The amazing floral profusion promises a timeless elegance whether it’s gracing ‘Snowbelle’s diminutive deep green foliage, the bouquets of a June wedding or a vase on your table. Small enough for a garden pot or for flanking a pathway, this handsome, low growing Canadian cultivar exhibits a tidy compact profile plus exceptional heat and cold tolerance.

Blooms May–June

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

Hardy to zone 4.

A stellar gathering of newly emerging leaves infused with bronze and purple hues and large single white sterile flowers exquisitely cradled by dark purple calyxes are this hybrid’s distinctive signature. Recently developed at the Memorial University Botanical Garden in Newfoundland by Dr. Wilf Nicholls, ‘Starbright’ inherits Philadelphus delavayi’s classy perfumed blooms and the dogged constitution of Canadian born, Philadelphus lewisii, which withstands drought, deer and cold. Its appealing dense upright frame can be successfully segued into mixed plantings, either massed or as a stand-alone specimen. (pp#18,651)

Blooms June–July

Size: 8' 0" – 9' 0" high x 6' 0" wide.

Hardy to zone 3.

Pure white semidouble blossoms create a delightful passage, ushering the last days of spring into summer’s warm embrace. Distinguished by a lovely orange scent, the pearly-hued profusion of large, cut flower-perfect blooms nearly envelopes ‘White Rock’s pleasing rounded habit. Appreciative of bright, somewhat moist, well-drained sites and a trim once the flowers are spent, this Philadelphus beckons us when in bloom, while its deciduous rich green foliage maintains a tailored appearance throughout the season.

Blooms May–June

Size: 4' 0" – 6' 0" high x 5' 0" – 7' 0" wide.

Hardy to zone 4.

Exceptional Echinops, Plants to freshen up your August garden, Saturday Strolls!

Exceptional Echinops!

The striking floral orbs sport either frosty white, cobalt blue or metallic-blue shades, while perched atop sturdy erect stems with handsome jagged-edged foliage. Cherished by pollinators, floral designers and gardeners alike, Echinops thrive in sunny, well-drained niches, though are tolerant of poor soil as well as rock-strewn or sandy sites. These undemanding European natives are perfect candidates for a formal border, cottage garden, meadow-style planting or a cut arrangement. Be sure to check out our online Echinops offerings.

Cool colors for your summer plantings….

Icy white, pale pink and chartruese shades perk up our August borders, while effortlessly blending with just about any color imaginable. These composed hues provide our eyes with bright, yet soothing focal points and an overall beat-the-heat ambience! Some of our cool-down favorites include: Echinops, Sidalcea ‘Elsie Heugh’  Euphorbia mellifera, Kniphofia ‘Green Jade’, Phlox ‘David’ and Tanacetum ‘Isla Gold’. I’ve also featured a handful of richer-toned flowers that I discovered on my early morning walk today. We hope you’ll try sprinkling a few of these perennials amid your landscapes and enjoy both their tranquil or more spirited effects.

Happy August and Happy Digging from all of us Digging Dog plant wranglers!
