Broadleaf evergreens have year round interest!

Often in spring we think we need flowers and color but evergreens are just as important to the landscape! Evergreens are often the bones of the garden. They are an integral part of winter, spring, summer and fall. Broadleaf evergreens are the trees and shrubs for all seasons because they have wonderful year round interest!

Rhdodendrons are wonderful for year round screening

The Benefits of Broadleaf Evergreens

They provide year round interest
Great for privacy screening
Drought resistant, once established
Provides habitats for birds and other small animals
Pollinator friendly!
Great for Martha’s Vineyards climate zone 7A (hardier than zone 7A).

Most broadleaf evergreens have a spectacular display of spring blooms!

Luckily they don't typically bloom all at the same time! Pieris japonica and Skimmia are the first to bloom, followed by the rhododendrons then azaleas.

BROADLEAF EVERGREENS OF THE WEEK

__________________________________________________

SKIP CHERRY LAURELS

Skip Cherry Laurels are vibrant evergreen trees that can create dense privacy hedges for any yard. Skip laurels grow to be 10-18 feet tall and 5-7 feet wide, with a moderate growth rate of roughly 24 inches per year. While they thrive in full sunlight, Skip laurels also fare very well in the shade. Their dense foliage is glossy green year-round. In the springtime, you’ll be rewarded with fragrant white blossoms that attract all kinds of pollinators. In fall and winter, Skip laurel trees produce red berries that attract songbirds.

Make excellent privacy screens

Green year-round
Fragrant, white blossoms in spring
Drought-tolerant
Smaller leaves than other laurels give a neat, compact look
Deer-resistant

***************************************

MAHONIA

Mahonia x media ‘Winter Sun’ is a small to medium-sized evergreen shrub capable of growing ten feet tall and five feet wide. It has a compact, upright growth habit with large, frond-like leaves that develop in whorls along its coarsely branched stems. Large spikes of fragrant, yellow flowers appear in late fall or early winter. The flowers develop into clusters of waxy blue berries eaten by many bird species. It is a dramatic focal point in the winter garden.

PLANTING TIP
Plant Winter Sun Mahonia in a sheltered, preferably eastern-facing site. It appreciates a moisture-retentive, but draining soil. Place where its blooms and fragrance can be readily appreciated in winter, such as near a path or seating area.

***************************************

AZALEAS

This year our spring flowering shrubs include the usual evergreen rhododendrons and azaleas. Azaleas are in the rhododendron family. Azaleas are a genus with many species. There are both evergreen and deciduous varieties available. ‘Most’ deciduous azaleas bloom after the evergreen azaleas. They will bloom on old wood before the plant has leafed out for the year.

Some deciduous, fragrant azaleas that we have available this year are:

Azalea viscosum, native swamp azalea: These bloom a little later and often bloom before the foliage emerges, making them extra showy. The fragrant blooms will perfume your entire property. They get 8-10ft tall and 6-8ft wide.
My Mary: A new yellow, fragrant, deciduous, spring blooming azalea that attracts pollinators and butterflies. It grows 4-5ft tall. (from Fern Brook)
Rhododendron prunifolium: Another azalea that we are carrying new this year. (from Fern Brook). Prunifolium is a species azalea (not a hybrid). It is a native wild azalea and is rare and hard to find. It is the first time we have ever had it!

There are some deciduous Weston hybrids with viscosum that stay smaller. If an 8ft shrub is too big for your spot try one of these :

Lemon Drop: A yellow blooming fragrant deciduous azalea
Innocence: A white blooming fragrant deciduous azalea

To see these deciduous azaleas in their full splendor they will be blooming in a few weeks at the Polly Hill Arboretum!

BUXUS (BOXWOOD)

This year we will have a great selection of Buxus, an evergreen deer resistant shrub. We have Green Beauty, Green Mountain and Wintergreen Boxwood. We also carry a variegated boxwood, as well as a selection of dwarf boxwoods, including one we propagate from the Polly Hill Arboretum. They do best in some afternoon shade and are a great back drop for deciduous plantings. Buxus typically bloom in May. “Even though the flowers are insignificant, Boxwood is on the RHS 'Plants for Pollinators' list, highlighting plants that produce large amounts of nectar and/or pollen. It is a great choice for encouraging beneficial insect wildlife into your garden!” (Plants | Candide)

Buxus that we have available:

Buxus sempervirens: A new variety we are carrying this year is Buxus sempervirens Dee Runk. This variety has an elegant columnar habit with a soft and lush foliage of ovate, lustrous leaves. Its deep green foliage has shown good resistance to boxwood blight.
Buxus microphylla var. japonica 'Winter Gem' : “An excellent evergreen shrub for small hedges. Among the hardiest of the small-leaved boxwoods, the rich green foliage can acquire a golden bronze hue in cold winter zones, but is one of the first to become green again in spring. Makes a wonderful addition to formal gardens, providing year-round interest.” (monrovia)

HOLLIES

We love hollies at Vineyard Gardens! Chuck Wiley, co-owner of Vineyard Gardens, grew up near a nursery in NJ, called Fernbrook, that grow beautiful American hollies, Ilex opaca. American hollies are more deer resistant than other hollies. They need a male and a female tree nearby for berry production.

American holly, Ilex opaca

“The stout, stiff branches of this pyramidal evergreen bear dark green, non-glossy, spine-tipped leaves. Bright red berries occur on the female plants. Many varieties are grown for ornament, shade, and hedges. You must have both a male and female plant to have berries, The male must be the same holly species as the female and bloom at the same time. This is a slow-growing tree (but slower growing is stronger). Berries are attractive and a good winter food source for birds.” (Ladybird Johnson Wildflower Center) The height of American holly grows up to 25ft. They can be pruned to be kept smaller.

Ilex opaca ‘Jersey Knight’: A male cultivar that is considered to be a good pollinator. typically grows to 7-8’ tall and spreads to 3-4’ wide over the first 10 years.
Ilex opaca ‘Jersey Princess’
Ilex opaca ‘Portia Orton’
Ilex opaca ‘Satyr Hill’

Japanese holly, Ilex crenata

“A dense, multi-branched, evergreen shrub with a rounded form that typically matures to 5-10’ tall and as wide. It is native to forests, thickets and mountain slopes in Japan, Korea, China and eastern Russia.. It has glossy, spineless, evergreen, deep green leaves which are attractive all year, white flowers which bloom in late spring (May-June), and black rounded berries which mature in fall on pollinated female plants.” (missouri botanical garden)

Ilex crenata ‘Steeds’

Ilex crenata ‘Helleri’
Ilex Crenata ‘Soft touch’
Ilex crenata ‘Compacta’
Ilex crenata ‘Green Lustre’

Japanese holly, Ilex crenata ‘Green Lustre’

Blue holly, Ilex x meserveae

“Bushy evergreen hybrids are (a) average height to 6-7’ tall, (b) glossy blue green leaves with prominent spiny margins, (c) purple stems, (d) greenish-white flowers in small clusters in May, (e) showy bright red berries on female plants in fall, often persisting until spring, and (f) excellent winter hardiness to USDA Zone 5.” (missouri botanical garden)

Ilex x meserveae ‘Blue Maid’
Ilex x meserveae Castle Spire’

other hybrids

Ilex x aquipernyi ‘Dragon Slayer’
Ilex x Oak leaf
Ilex x Koehneana
Ilex x Nellie R Stevens
Ilex x Winter Bounty

Inkberry, Ilex glabra

“A mound-shaped, colony-forming shrub 6-12 ft. tall and wide. Lance-shaped, sparingly-toothed, glossy, leathery foliage varies in color from dark- to light-green both in summer and fall. Inconspicuous flowers are followed by black berries which persist well into winter. This species differs from all other evergreen hollies by lacking spines on the leaves, only having teeth toward the tip of the leaves.” (Ladybird Johnson Wildflower Center)

Ilex glabra ‘Compacta’

Ilex glabra ‘Shamrock’

Winterberry, Ilex verticillata

“The leaves of Common winterberry are not shaped with sharp teeth like other hollies and are not evergreen. The purplish green foliage turns black, in fact, with the first frost. The inconspicuous flowers, however, are followed by dense clusters of bright red berries that remain on the branches throughout winter. Winterberry is a globular, upright, medium-sized shrub, typically 6-10 ft. tall. Extremely showy in late fall and early winter when covered with their bright red fruit, these shrubs are either male or female--a trait typical of the holly family. Birds are readily attracted to them.” (Ladybird Johnson Wildflower Center)

Spring Flowering Shrubs

LILACS

We have a great selection of lilacs starting to bloom now! .

Canadian Lilac, Syringa vulgaris Pocahontas: The species of the purple lilac, Syringa vulgaris, is said to be the most fragrant (but they are really all fragrant). Extend the lilac season with this extremely hardy, early blooming variety. Deep maroon-purple buds open in early May to fragrant, deep violet blooms 7 to 10 days before common lilac varieties bloom. Reaches 10 ft. tall and wide.
Korean Lilac, Syringa patula Miss Kim: Try a Miss Kim Lilac if you need one that stays a little smaller. This upright, compact lilac blooms later than others, extending the season with deep purple buds that reveal clusters of highly fragrant, lavender-blue flowers. Foliage is burgundy-tinged in fall. Reaches 6 to 8 ft. tall and wide
Charles Joly, Syringa vulgaris: This is a great choice if you want a larger lilac,10-12ft tall. Gorgeous, deep wine red, double flower clusters are highly fragrant. Blooms mid-season, typically in mid-May. A lovely spring accent, screen or border specimen.
Sensation, Syringa vulgaris: A bicolor purple and white flowering lilac. A mid-season bloomer that typically flowers in mid-May. Branches are erect and open with rich green foliage. Use to create a beautiful spring flowering hedge, screen, or accent.
Dwarf Korean Lilac, Syringa meyeri ‘Palibin’: This is another species of lilac that we carry which stays much smaller. This one has smaller leaves and smaller purple blooms that are also fragrant. Blooms profusely in midseason, typically mid-May, and first flowers at an early age. Use in shrub borders with an evergreen background or plant in groups to form a low hedge.
We also carry white French Lilacs

Plant your lilacs in full sun, well drained, rich soil and you will have fresh lilac bouquets every spring!

Honeysuckle

SHRUBS

One of my favorite spring flowering shrubs is the fragrant honeysuckle, Lonicera fragrantissima. It is extremely fragrant, long blooming and comes back bigger and better year after year. This early bloomer fills my whole yard with perfume every spring. It does best in full sun but will do fine in partial shade.

VINES

This year we have 3 varieties of fragrant honeysuckle vines.

Mandarin, Lonicera x 'Mandarin': “Delightful, tubular, mandarin orange flowers with pale orange interiors on this vigorous vine with a twining habit that will quickly cloak shade arbors, old trees, and woven wire fences. Drape over walls or let it sprawl across the rooftop for cottage garden charm.” (monrovia)
Major Wheeler, Lonicera sempervirens: “Blazing red and gold blooms appear all summer long, and into fall. Stems are often red to purple turning greenish brown with age. A vigorous, fast growing vine, perfect for covering a fence post, arbor or trellis. This excellent selection thrives in high humidity and is mildew-free.” (monrovia)
Goldflame, Lonicera x heckrottii: “An excellent vine to use as a cover for trellis, arbor and fencing. Also works well when pruned to form a dense shrub-like shape. Purple to deep pink buds open to sweetly fragrant, golden yellow, tubular flowers throughout summer.” (monrovia)

Hummingbirds love them!

Rhododendrons

This year our spring flowering shrubs include the usual evergreen rhododendrons, as well as deciduous azaleas which are in the rhododendron family. They are shallow rooted plants that grow as an understory in the woodlands, like in the Blue Ridge Mountains. They are also found in various parts of Asia, like China and Nepal. They grow in high elevations because they like it cool.

Rhododendron cawtabiense, also called cawtaba rhododendrons:

Roseum Elegans: Medium sized broadleaf evergreen shrub that reaches 9-12’ tall and wide. Beautiful rose-lilac colored flowers. Best along a woodland border.
Grandiflorum Catawba: (Native)The Catawba evergreen rhody reaches 6-8’ ft tall & wide and has lilac-purple, trumpet-shaped flowers. It is beautiful planted in a grouping, as an informal hedge or a mixed or woodland border. They are in bud now!
Chinoides Rhododendrons: A smaller rhody that gets to about 4’ with white bell shaped flowers. Outstanding for use as an informal hedge or foundation plant.
Cunningham’s White: A smaller rhody that gets to about 4’. It’s a perfect middle-of-the-border flowering shrub. A natural under oaks and older coniferous trees. Also perfect in the woodland understory and in wild gardens.

*********************

Rhododendron maximum : (Native) A large broadleaf evergreen reaching up to 15ft by 12ft wide. They prefer to grow in cool, moist spots with well drained soil, part shade to full shade. They have dense, large leathery leaves with rose-purplish to pink to white blooms. They are in bud now!

*********************

Hybrids developed by Weston Nurseries.

PJM: A durable rhody that tolerates heat as well as cold. An excellent choice for borders, mass plantings, or containers. PJM’s are smaller leafed rhodies with bright laveder purple blooms, developed at Weston Nurseries. They are blooming now!
Olga Mezzit: A compact smaller leaf evergreen, developed at Weston Nurseries. More heat and sun tolerant than other varieties. An excellent choice for borders, mass planting, or containers. They are blooming now!

*********************

Many of the deciduous azaleas are native, including viscosum and its hybrids.

Rhododendron viscosum: (Native) Native to Martha’s Vineyard! Gorgeous and fragrant.

They need to be watered often when newly planted!
Rhododendrons benefit from an application of mulch to keep moisture in the soil for their shallow roots.
