BROADLEAF EVERGREENS

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!

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

__________________________________________________

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’

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’

  • 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)
