Viburnum

Viburnum

Viburnum, whether evergreen or deciduous, is certainly a shrub for all seasons: there’s ‘Diana’ to usher in spring and ‘Summer Snowflake’ adorning graduation and June weddings. Blazing with autumn color, and all bearing lustrous fruit through winter to attract feathered visitors, these graceful shrubs exhibit an enduring cold hardiness.

They prefer rich, moist soil and bloom best in full sun, but can also tolerate partial shade.

<i>Viburnum</i> x <i>burkwoodii</i> ‘Anne Russell’

A recipient of the RHS award of merit in 1957, dense mounding ‘Anne Russell’ boasts pink buds and copious, 3 in. waxy white flowers, which exude the most divine scent. The glossy dark green leaves turn a luscious crimson-purple in the fall. We favor it as an informal hedge or as a semideciduous specimen for the shrubby border and come spring, indulge in its fragrance each time we pass by.

Blooms April.

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

Hardy to zone 4.

<i>Viburnum</i> x <i>burkwoodii</i> ‘Conoy’

This evergreen Viburnum was the last, and possibly the finest, of Dr. Egolf’s introductions. Dark red buds open as creamy white to pink flowers amidst the most lustrous of all Viburnum foliage. Later, persistent glossy red fruit brightens the fine textured, deep green leaves, which are pale olive-green underneath and tinged with deep maroon in winter.

We are fond of this compact, colorful, low spreading shrub in containers, as a dense informal hedge, or in mass plantings.

Blooms late April.

Size: 4-1/2' high x 7' 0" wide.

Hardy to zone 6.

An ornamental prodigy from Dr. Donald Egolf’s esteemed breeding program, ‘Mohawk’s allure spans several seasons. Its first offering begins in spring when glistening dark red flower buds appear, followed by the spicy gala of clove-scented snowball-like blooms amid polished foliage, and continues through its brilliant orange-red autumn finale. Anticipation builds as clustered shiny buds wait a few weeks to open, revealing enticing, rouge-backed, waxy white flowers.

Amenable to varied conditions, yet flourishing in moderately moist well drained soil, this compact deciduous shrub hosts disease resistant dark green leaves, and can be cast as a star specimen, planted en masse or transformed into a picturesque backdrop.

Blooms late April – May.

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

Hardy to zone 5.

<i>Viburnum carlesii</i>

This much loved Japanese and Korean denizen has tantalized gardeners with its sweet vanilla-laden scent since 1906. First appearing in late autumn on naked light brown branches, the clustered red buds stir our interest as we eagerly await spring and the snowball-like 3 in. wide cymes of pink flowers, which mature to crisp white against broadly ovate dusty green deciduous leaves. Aside from the fabulously fragrant blooms, the grand slow-growing Korean Spicebush offers plenty of reasons to invite it into your garden: red and black fruit (a beckoning sight for hungry birds), wine-red fall color, attractive smallish rounded frame plus a trouble free low maintenance constitution.

Blooms March-April

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

Hardy to zone 4.

Some say her ambrosial fragrance can waft over 30 ft. away. We say you’ll want to plant this compact, medium-sized beauty as soon as possible. Tinged chocolate when young, the broadly ovate, serrated foliage matures to a dusty dark green with fuzzy gray-green undersides, and in fall broadcasts purple-red shades. Dome-shaped clusters of red buds herald the posh pink flowers which brighten to a satiny white, emitting the most irresistible Daphne-like perfume.

Mingling amid other broadleaf shrubs, positioned alone or employed as a hedge, the energetic deciduous ‘Diana’ should stay close to a well-traveled, moist sunny spot.

Blooms late March to mid-April.

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

Hardy to zone 4.

Pink buds burst forth into waxy white blossoms as spring’s tender greenery attires this relatively tightset Egolf cultivar. Rounded flower heads feature bud and blossom simultaneously, creating a lovely two-toned effect. Lining the spreading branches, handsome, semisheened dark green foliage gives way to an orange-red hue in fall. A stellar stand-alone in the mixed border, ‘Cayuga’ claims Viburnum carlesii and Viburnum carlcephalum lineage, and adapts to an array of growing conditions.

Blooms late April.

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

Hardy to zone 5.

Vibrant color is the hallmark of this captivating newly introduced Viburnum. Embellished with exquisite, flat white lace-caps, the robust rounded habit spawns handsome deciduous 5-lobed maple-like leaves, which emerge a vivid red, age to lambent golden yellow, then flush dark tangerine and burgundy hues in autumn. Bunches of translucent scarlet berries keep the birds happy and our interest sparked. A versatile eye-catching specimen, Cranberry Bush thrives in any reasonable garden soil, enjoys protection from hot afternoon sun and exhibits superior cold hardiness.

Blooms May–June

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

Hardy to zone 3.

<i>Viburnum plicatum f. tomentosum</i> ‘Molly Schroeder’

Headlining pretty pink, flat topped lacecaps poised on tiered horizontal branches, this sterling Viburnum selection from New Zealand promises a repeat autumn bloom and consistently pink flowers year after year unlike other cultivars that fade to white. Broad handsome deciduous foliage–dark green, prominently veined and purplish red come fall–cloaks her easy-going rounded frame. Full of rosy panache, ‘Molly Schroeder’ can be planted alongside Sambucus ‘Black Beauty’ and Physocarpus ‘Dart’s Gold’ with Epimedium ‘Amber Queen’ blanketing the ground below for a festive springtime vignette.

Blooms late April–May.

Size: 5' 0" – 8' 0" high x 5' 0" – 8' 0" wide.

Hardy to zone 5.

The most outstanding feature of this deciduous Viburnum is its horizontal growth habit, with flowers and fruit in parallel rows along the branches. 'Shasta' boasts deeply veined, dark green foliage with a light fuzz on the underside, turning to glowing purple-red at summer's end. Profuse, white flower clusters and lustrous fruit abound in true Vibrunum style.

Blooms April–May

Size: 6' 0" – 8' 0" high x 8' 0" – 10' 0" wide.

Hardy to zone 5.

<i>Viburnum plicatum</i> f <i>plicatum</i> ‘Popcorn’

Heralding summer, this densely growing Viburnum displays sprightly round clusters of clean white flowers, borne in such profusion they nearly obscure the good-looking deciduous foliage. Autumn brings brilliant scarlet hues to the veined deep green leaves. Let Geranium ‘White Ness’ brighten its base while echoing ‘Popcorn’s greens and snowy whites.

Blooms June.

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

Hardy to zone 5.

<i>Viburnum plicatum f tomentosum</i> ‘Summer Snowflake’

The most exceptional attribute of this deciduous Viburnum is its horizontal growth habit, featuring flowers and fruit in parallel rows along the branches. Distinguished by a smaller stature, and foliage that’s not quite as large as Viburnum ‘Shasta’, ‘Summer Snowflake’ maintains a more rounded form and blooms well into summer with an extravagant offering of pure white lacecap flowers. It’s lovely in containers, grouped in a drift, or as a star specimen.

Blooms April – August.

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

Hardy to zone 5.

Our featured plant: Achillea 'Hella Glashoff'

Amazing Achilleas, Invigorate your summer plantings!

Amazing Achilleas…. These sturdy, dependable perennials produce small indivdual blooms that populate broad, flat flower heads, lending welcome horizontal elements to any garden bed. Ideal for bouquets, fresh or dried, the long-lasting blossoms range in color from alabaster to soft yellow and gold, as well as terracotta, pink and sassy red. Cut back their flowers in midsummer and enjoy a fall encore! Spicy scented, attractive fern-like green or gray-tinged foliage cloaks their strong straight stems. Slowly spreading and somewhat drought tolerant, Yarrow seem to thrive on neglect. They can handle low soil fertility plus coastal wind and salt spray. Be sure to check out our diverse on-line Achillea selections!

Invigorate your summer plantings.… A few simple maintenance techniques will help plants appear fresh throughout the upcoming dog days of summer. The addition of a chipped bark mulch or well-rotted compost, applied as a top-dressing, not only reduces water requirements, but generally makes it easier for plants to maintain perky looking leaves and vigorous habits. A July or early August trimming of long-blooming perennials, such as Nepetas and most Geraniums ensures myriad flowers that will keep on coming ‘til the first frost. Featured in this newsletter, you’ll find the fabulous plants that caught my eye as Boobah and I took our morning walk through the nursery and adjacent display borders this past week. Hopefully, you’ll have room to ensconce several of them in a well-traveled spot. Happy Digging!
