Winter-Fruiting Trees for Lasting Beauty

‘Winter King’ green hawthorn has persistent fruits that are loved by cedar waxwings.

Now that fall has passed, it is a dismal thing to look out the window and see no color. But, this does not have to be the case if you plant beautiful trees that still offer bright colorful fruits to the garden in winter. The first one everybody thinks of is holly, but there are several more that fit the bill.

American Holly

American holly has a classic holly look and the trees can become very large.

American holly (Ilex opaca, USDA Hardiness Zones 5-9) is an eastern native tree that can survive in some shade but grows and looks best in an open area with full sun. The pyramidal tree can reach up to 50-60 feet tall, so find a big place in your yard or garden to plant it.  It has leathery evergreen leaves and bright red berries that turn from green to red in fall that stay on through the winter. A caveat is that it is a dioecious tree, which means that plants have either female or male flowers, never both. That means that both male and female plants are needed to produce fruit. One of the oldest and best varieties is the heavy-fruiting,  ‘Jersey Princess‘, which was bred at Rutgers University. It fruits heavily and has a neat, narrow habit. A good pollinating partner is ‘Jersey Knight‘. Be aware that the leaves are very prickly, so wear thick garden gloves with gauntlet sleeves when handling them.

Yaupon Holly

Smooth-edged leaves and pretty winter berries make this a fine holly tree for southern gardeners.

The more southern sun-loving yaupon holly (Ilex vomitoria, Zones 7-9) has smooth-edged leaves and female trees develop copious red berries that remain on the stems through much of winter. It is a native species that naturally exists in open coastal woods from Virginia down to Florida and across to Texas. Wild specimens can reach up to 45 feet high, on rare occasion, but generally do not exceed 25 feet. The golden-berried ‘Anna’s Choice‘ is a lovely female variety reaching 15 feet that bears lots of sunny fruits against its fine, scalloped leaves. ‘Will Flemming‘ is an unusually upright narrow male yaupon holly tree that reaches 12-15 feet. Its spring flowers will pollinate female trees, like ‘Anna’s Choice’.

American Wahoo

American wahoo is a spectacular tree that deserves more attention in landscapes and gardens.

American wahoo (Euonymus atropurpureus, Zones 3-10) is a relative of the invasive non-native burning bush (Euonymus alatus), but in fall this non-invasive eastern native shows off exceptional pinkish-red fruits with orange inner seeds as well as purplish-red leaf color. In spring it bears purplish flowers. The multi-stemmed tree can reach up to 20 feet and looks best when planted as specimen trees in a sunny, open lawn. Well-drained, fertile soil is needed. Some stem pruning must be done to encourage an open trunk. Birds love the fruits.

Green Hawthorne

‘Winter King’ offers one of the most spectacular displays of red fruits is any tree.

The green hawthorn (Crataegus viridis, Zones 4-7) is a small native tree that exists across much of the eastern United States. Wild specimens have large thorns up and down stems, so approach this tree with caution.  ‘Winter King’ is an improved variety with spectacular red fruits in winter, profuse white flowers in spring, very few thorns, and silvery bark. The scarlet fruits (called “haws”) resemble very little apples, and technically they are edible, but most gardeners leave them to the birds. (European hawthorns (C. monogyna) are a bit larger and often used to make jams and jellies.) In fall, the leaves turn purple and scarlet, and the brilliant red fruits last well into winter.  ‘Winter King’grows 15 to 20 feet tall, adapts to any kind of well-drained soil and is drought tolerant and disease resistant.

Crabapples

Birds love the jewel-like fruits of crabapples.

There are literally thousands of flowering crabapple varieties. The best flower and fruit beautifully and are very disease-resistant. One that comes highly recommended by my daughter is ‘Prairifire’ (Malus ‘Prairifire’, Zones 4-8), a highly disease-resistant variety first introduced in 1982 and developed by Dr. Daniel Dayton of the University of Illinois. It displays some of the most stunning hot-pink spring blooms against purplish-red spring leaves that turn dark green in summer and bronze-red in fall.  Its fall crabapples turn bright red and are held into winter until birds pick them off. The tree reaches about 20 feet tall, needs full sun, and resistants many foliar diseases that attack crabapples. Plant it in full sun for best growth and flowering.

Any one of these trees, or all of them, will brighten your winter landscape. I hope this has given you some plants to buy when planning for any garden additions for next season.

Viburnums For Any Landscape

Right: bright red Viburnum opulus berries, do droop. They also feed hungry songbirds.

What exactly is a Viburnum? Viburnums are trees or shrubs, evergreen or deciduous, that may be diminutive three-foot globes or grow 60 feet tall. Their leaf texture varies from smoothly shiny to velvety, and, their leaf edges may be serrated, dentate, lobed, or not! Viburnum flowers are either round or flattish and range in color from white to pink. The blossoms are either deliciously fragrant, have absolutely no scent, or can be downright offensive. Just forget trying to determine what viburnum you are admiring by its fruit color alone since berries range from yellow to orange, red to black, and blue to purple.

According to the great Georgia plantsman, Dr. Michael Dirr, their characteristics are simply too varied to make a definitive identification without a very good reference guide. In his 2007 guidebook, Viburnums, Flowering Shrubs for Every Season, by Timber Press, Dirr admits that even taxonomists can’t agree on how many species presently exist in the genus Viburnum with the true number probably falling somewhere between 160 to 250.

What makes a Viburnum a Viburnum?

The Koreanspice bush, V. carlesii, provides a perfect example of a viburnum’s opposite leave arrangement.

Famed tree and shrub specialist Michael Dirr’s definition is:

  1. The fruit is a drupe, generally ellipsoidal, flattened, ovoid to rounded, with a fleshy coat, hard bony endocarp, and a single seed within; and
  2. The leaves are always arranged opposite; a few species, occasionally, have three leaves at a node.

Growing Viburnum

Besides their exquisite beauty, the main reason why we embrace viburnums in our home landscapes is their extreme hardiness. Many varieties can be very drought tolerant (once established) as some of our best Southeastern native viburnum hail from dry woodlands. A few, such as our native Arrowwood, will also tolerate wet feet. Most will grow well in full sun to part shade, can take a variety of soil types, and still thrive.

Planting Viburnum

In the absence of good soil, you could amend the planting hole fill dirt with Black Gold Garden Soil for improved drainage that will still provide enough moisture retention essential for a newly transplanted viburnum. Otherwise, mulch the base of your new addition with Black Gold’s Garden Compost Blend in order to help hold moisture, keep developing roots cool in summer and warmer in winter, and to suppress weeds.

Great Viburnum

In my home landscape, I have found several species of viburnum grow well under the canopy of a large Black Walnut tree, where it is very dry. Here I have planted Koreanspice bush (V. carlesii) and Cranberry viburnum (V. opulus), and they both perform beautifully.

Viburnums have also been evaluated for their resistance to deer grazing. The toughest survivors of deer predation are our native Arrowwood (V. dentatum); Blackhaw (V. prunifolium); Smooth witherod (V. nudum), which is sometimes erroneously called “possum haw” and, the Maple-leaf arrowwood (V. acerfolium).

Koreanspice Viburnum

Koreanspice viburnum (V. carlesii, Zones 4-7) is one of our most popular, old-fashioned, pass-along southern shrubs. Grown for its intensely sweet springtime fragrance, the late March to early April flowers of Koreanspice begin pale pink, turning white with age, grow 2-3 inches across, and are rounded. This 8-10 foot tall shrub has dull green leaves that turn reddish in the fall, and red to black fruits.

Cranberry Viburnum

Cranberry viburnum is named for its brilliant cherry-red fruit clusters that begin coloring in late summer. The popular double-flowered variety ‘Roseum’ is sterile and bears no fruit.

The Cranberry viburnum is named for its brilliant cherry-red fruit clusters that begin coloring in late summer. Its famous leaf fall color is much more dramatic in cooler regions where leaves turn gold, red, and burgundy. A very good cultivar is V. opulus ‘Compactum’, which should top out at just 5-6 feet.

Chinese Snowball

For sheer drama, nothing compares to the Chinese Snowball (V. macrocephalum). This multi-trunked small tree can reach 12-feet or more in height and grow just as wide. Sometimes semi-evergreen in mild winters, this very dark-leafed viburnum is beloved for its 6-8 inch, rounded, springtime flowers that begin pale chartreuse and age to purest white. They are so beautiful that we can forgive it for not bearing any scent. A significant bonus is that it also flowers again from late summer into fall. Since the Chinese Snowball’s hydrangea-like flowers are sterile, there is no fruit, therefore no unwanted seedlings.

Bodnant Viburnum

Your winter landscape could be delightful including a Bodnant viburnum in it. Viburnum x bodnantense ‘Dawn’ has bright pink, strongly perfumed flowers in late February to early March in my Wake Forest, North Carolina, Zone 7-8 garden. The small, rounded, sweetly fragrant flowers are borne on bare branches on a rather rangy shrub, but ‘Dawn’ blends nicely into the mixed border the rest of the year.

Viburnum Tinus

Garden centers offer V. tinus ‘Spring Bouquet’ in autumn, which is the right time to plant them. During the late fall months ‘Spring Bouquet’ forms tight rose-colored clusters of buds that will start popping open during the first months of the new year. These viburnum flowers are only slightly fragrant, but they will cover the small shrub. This evergreen viburnum will need part shade in summer, winter protection from sun, plus they benefit from being shielded from desiccating winds.

Doublefile Viburnum

Doublefile viburnum (Viburnum plicatum) has lovely tiered branching and should not be pruned.

Since they bloom in early April, Doublefile viburnums, V. plicatum f. tomentosum, are great substitutes for ailing native dogwoods. Named for its flowering habit of doily-flat flowers positioned side-by-side along the top of long horizontal branches, this is a stunning small tree. These viburnum are deciduous in winter, have dark green foliage in summer, and bright red berries in late fall. A cultivar named ‘Summer Snowflake’ will bloom well in early spring, then sporadically repeat off-and-on throughout the summer.

Chindo Viburnum

Chindo viburnum is another popular viburnum that isn’t grown for its flowers at all. Promoted by the late Dr. J C Raulston of North Carolina State University, V. awabuki ‘Chindo’, is a loosely pyramidal-shaped, shiny-leafed, evergreen shrub that can reach 15-20 feet. It grows in sun or shade and is shaped reminiscent of a large-leafed holly, so it makes an ideal screening plant. One warning is that a Chindo viburnum won’t like winter temperatures that drop below zero; so, if it does get that cold you may have to trim your plant back severely in springtime to encourage new growth to flush.

There is probably a perfect viburnum for just about any location in your landscape, so how do you go about narrowing your selections? Ask your garden center professional for their recommendations, check with your local Cooperative Extension Service, and find a copy of Dirr’s Viburnums book.

Gravelscape and Green your Front Yard

Gravel can make architectural plants stand out like sculpture. (Image by Maureen Gilmer)

Nowhere are water-needy lawns disappearing as fast as in arid southern California and the American Southwest. This is the proving ground for a lot of alternatives to traditional turfgrass. A big problem is always the front yard, where your property value is rooted in curb appeal. What you do there will have a big impact on the future marketability of your home. This is why unconventional front yard solutions, no matter how sustainable, may cost far more than you realize, but desirable low-cost options do exist.

Gravelscaping

A border of colorful succulents stands out against a gravel patio.

The most versatile and affordable replacement material for lawns out west is gravel, due to lower cost, availability and color range. Spreading gravel takes muscle, but it’s an easier DIY project than precision placement of precast concrete units. Gravel can be raked and walked on, leaving a beautiful blank canvas to envision your dryland planting ideas.

All manner of bold cacti and succulents look great against a gravel base. You can even color coordinate your gravel colors and textures with regionally appropriate plantings for a sharp, clean, low-water landscape your neighbors will appreciate. Just be sure to consider plantings as you plant your gravel lawn, so you can establish them as you lay your gravelscape. Increasing soil fertility, with enrichments such as Black Gold Cactus Mix and Just Coir, will give your low-water plants a head start.

Replacing Lawn with Gravel

Here are eight rules we have learned in the desert to guide your lawn replacement with gravel:

  1. Use proper edging. Where your gravel ends, problems begin. Use a solid edge boarder (metal, wood, plastic) that is at least 1 to 2 inches above grade to ensure no spill over onto adjacent beds or paving.
  2. Lay dividers between gravel colors. It’s fun to use more than one color to create just the right look, but if you don’t divide them well, they eventually merge together resulting in a visually muddy colored mess. Make plans for a substantial divider within that great crisp edge you created.
  3. Insist on professional-grade weed barrier. Landscape suppliers provide thick, heavy-grade weed barrier fabric that is easy to install and long lasting, though a bit more expensive than consumer grade. It stays put, won’t tear and most importantly, resists decomposition far longer.
  4. Be sure all the lawn is dead. Failure to kill all of the grass and weeds that once grew in your lawn can doom your gravel to future infestation. Even with weed barrier fabric, Bermuda grass can travel many feet underneath to find light and water, if not properly eradicated before-hand.
  5. Choose the right gravel from the start. Though weed barrier helps keep gravel from your soil, some gravel will always make its way in. If you bring in gravel that’s in high contrast with your soil color, it’s there to stay. In the future, some of it will mixed in to forever speckle that ground.
  6. Avoid dark gravel in hot climates. Dark gravel colors absorb heat quickly, then radiates it back into adjacent spaces after sunset. Conversely, white gravel is coolest but causes glare. Neutrals are ideal.
  7. Grade and ensure adequate thickness. Gravel should be laid from 2 to 2.5 inches thick on a uniform surface. When adding gravel to critical junctures with paving, the ground must be dug out so all grades are even. Too often the gravel layer is thinned to meet the patio surface grade, which always results in bald spots at these high traffic areas.
  8. Pedestrians first. Round river gravel is great to walk on, but it rolls easily, so it cannot be used on an incline. Crushed gravel has sharp edges and points that dig into moist earth for anchorage but is not easy on the feet. Always consider gravel texture on walkways in your design, especially with respect to senior citizens and small children.

Everyone can have a beautiful gravel front garden the neighborhood will love. Make it broad and beautiful, in any style, so your property values are maintained while conserving water.

Gravel Style Guide

A selection of different types of gravel.

Different gravel textures and colors yield different looks and offer different functionalities. Here are some of the most common design styles using gravel:

Earthy: Fine, sand-colored gravel can be swept to visual perfection to make architectural plants stand out like sculpture.

Transitions: This fresh edge between green and rosy gravel (below) is not sustainable without a strongly defined divider to keep it crisp; rose gravel already too thin at top of concrete slab where grade is much too high.

Thyme Lawns

Vita Sackville-West’s twin time lawns are shown in the foreground of the beautiful landscape at Sissinghurst Castle.

In Queen Elizabeth’s day, everyone had to bathe at least once a year, whether they needed it or not. Clothing was not washed more frequently either. This period, with its voluminous skirts and skintight corsets, made communal living quite odiferous after awhile. The only solution was to cover up the stink with the scent of garden herbs.
