Smoketree, the common name for the genus Cotinus, aptly describes the hazy, smoky look of the flowers sported by this fabulous plant. Best described as a deciduous large shrub or small tree, Cotinus boasts species with varying heights, unique summer flowers, outstanding fall color and low maintenance requirements, all features that can make it an excellent addition to your landscape.

Cotinus Care

Thriving in full sun, the smoketree isn’t particular about soil conditions; it is drought tolerant and virtually disease and pest-free. Cotinus does, however, require excellent drainage, and it is important that the soil not be soggy or compacted which will choke off roots. Although this plant may be pruned for size it is important to remember that the flowers appear in the late spring on old wood, therefore, fall or early spring pruning will eliminate the smoky flowers. When pruning is required to maintain size or shape, consider coppicing (cutting entire bush down to 12″ tall in early spring) every other year. This allows you to enjoy the flowers on alternate years but keep the plant to a manageable size.

Cotinus Varieties

We recommend two species and various varieties of Cotinus because of their sizes, colors and landscape beauty. The large C. obovatus, American Smoketree, is native to the eastern United States. A large specimen grows to 20′ tall and wide, with large bluish dark green leaves. In the fall, the leaves turn bright yellow, orange and bronzed red.

The smaller C. coggygria generally grows to 15-20′. The flower puffs of the purple-leaved cultivars ‘Purpureaus’, ‘Royal Purple’, ‘Norcutt’s Variety’ and ‘Velvet Cloak’ appear even stronger purple than the dramatic leaves. Especially when positioned against a light colored fence or wall, the purples seem to glow.

On the other hand, ‘Golden Spirit’, growing to only 7′ tall with lime green spring leaves, stands out against dark walls and fences, whether in the ground or in a container. ‘Pink Champagne’ pairs tannish-pink flower puffs with green leaves for a 10′ tall and wide, clean, contemporary look.

One of our favorites, ‘Grace’, is a hybrid of the two species. Growing to 15′ tall and wide, the purple leaves create a beautiful backdrop to large, deep pink smoke puffs. Autumn foliage colors include orange and a stunning red/purple/bronze.

Choosing Your Cotinus

With so many varieties of this stunning plant available, it can be difficult to choose your best Cotinus. Check the specific growing conditions for each variety, as well as its mature size, when selecting one for your landscape. Care for it meticulously until established, and you’ll be rewarded with many years of dramatic beauty to enjoy.

Adding structure and an aspect of year-round permanence to any yard, small shrubs are excellent for enhancing the perennial border. Thought of as the spine and bones of good landscaping, small shrubs hold the soft body of flowers together and add consistency between areas. Well-chosen selections integrate with perennials to add interest for more than just one season. Not only do they add support for perennials in late summer but also they provide definition to the bed throughout the year. Though shrubs take longer to reach maturity, their outstanding foliage, lovely flowers and attractive shapes and forms add to the beauty of the garden.

Choose Shrubs That Promise Year-Long Interest

The ideal shrub for the mixed border has outstanding foliage – deep green, purple, gold, silver, or even variegated. Its leaves may be glossy, soft or even fuzzy to touch. Colorful veins or other variations may mark its foliage to seize your interest throughout the seasons. And, certainly, the ideal shrub has flowers. Late-blooming flowers liven up the border during the tired end-of-summer days, while early-blooming varieties add excitement to a garden just bursting into spring. You’ll also want to take into account flower color when working shrubs into a planting scheme. White is a delightful and safe choice because it harmonizes with all other colors. Consider also mellow blues, pinks and other pastel shades to add a peaceful mood to the garden. Bold colors of yellow, orange or red will add a warm, daring feeling and dramatic interest. In fall, colorful leaves cover the ideal shrub before falling to the ground. And in winter, twisted, colorful branches and bright berries provide visual interest even under a layer of frost or snow.

Top Border Shrub Choices

*Prune hard in late winter to control height in mid-border positions.

Ornamental Grasses lend a unique dimension to any landscape with their texture, sound, motion and architecture. By planting ornamental grasses, you can also add multi-seasonal excitement to your landscape. Either combined with other ornamental plants or featured by themselves in “Grass Gardens,” ornamental grasses are attractive from spring until late fall and often through winter as well.

Choosing Ornamental Grasses

It can be challenging to select the best ornamental grasses for your landscape. Choose from varieties that are short or tall, upright or weeping. Foliage can be bold or fine and comes in colors ranging from green, blue-green, lime-green, gold and red to variegated with horizontal or vertical bands of white or yellow. Flower heads can be showy plumes, fuzzy foxtails or airy particles and appear from mid-summer to fall, depending on variety. Dried flowers and leaves may persist into winter, looking particularly effective against a snowy backdrop.

Depending on the conditions of your landscape and your grass preferences, there are many different types of grasses to try.

Screens Or Barriers

Taller growing varieties such as Plume Grass (Erianthus ravennae) or Giant Miscanthus (Miscanthus floridulus) can be used as effective screens or windbreaks. The wind rushing through their foliage creates added sensations of sound and movement. Even some of the medium-sized growers, such as varieties of Miscanthus sinensis, can enclose a patio or act as a barrier against wind, noise or an undesirable view.

Specimens

Many ornamental grasses also make excellent specimen plants and can turn a dull corner into a focal point of color and texture. Some of the most dramatic grasses for specimen planting include Maiden Grass (Miscanthus sinensis gracillimus) with its graceful arching vase shaped foliage and pinkish blooms which age to cream, and Porcupine Grass (Miscanthus sinensis ‘Strictus’) that has upright green and yellow banded stems.

Waterscaping

Water gardens and ornamental grasses go together beautifully. A grouping of grasses looks particularly effective at the water’s edge, softening the boundary between land and water. Many grasses such as Miscanthus can tolerate moist conditions, some, like sweet flag (Acorus) and Giant Reed (Arundo donax), can grow in shallow water. Sedges (Carex), which are not true grasses, although similar in appearance, are also moisture-tolerant. Look for varieties with plain, variegated or golden foliage.

Groundcovers

Grasses that are groundcover varieties spread by underground stolons rather than forming tight clumps. One such selection is Ribbon Grass (Phalaris arundinacea ‘Picta’), a fast-spreading green-and-white variegated variety, particularly useful as a groundcover in difficult areas such as slopes or even under trees that cast light shade. Give this one plenty of space! You’ll also want to try green or variegated Liriope and Black Mondo Grass (Ophiopogon).

Beds and Borders

Massed in groups, ornamental grasses are wonderful as a background to, or in combination with, other plantings. Try planting them with perennials such as Black-eyed Susan, Sedum ‘Autumn Joy’ and Veronica ‘Goodness Grows’ or ‘Sunny Border Blue’ for a dynamic summer and fall interest addition to your landscape. Varieties for mass planting include Switch Grass (Panicum virgatum), whose upright delicate flowers are held above leaves that turn reddish in the fall; Korean Feather Reed Grass (Calamagrostis acutifolia ‘Stricta’) which yields stunning buff-colored plumes over a long period and Fountain Grass (Pennisetum alopecuroides) that sports maroon foxtails which age to cream in late fall. A number of different forms of Fountain Grass are available: ‘Hameln’ is a dwarf variety with creamy foxtails, while ‘Moudry’ has unusual black flowers. For edging beds and borders, plant low-growing Blue Fescue (Festuca glauca). Its steely blue clumps hold their color though winter and contrast well with pink or purple flowers or foliage.

Growing Grasses

Ornamental grasses are relatively easy to grow. A site that receives at least six hours of sun per day is best, although varieties such as Hair Grass (Deschampsia) and variegated Miscanthus (Miscanthus sinensis ‘Variegatus’) can grow well in as little as four hours of sun. Soil preparation, as with everything you plant, is a must, so work in plenty of organic matter such as peat moss, humus or compost. Fertilize in early spring with 5-10-5 or bone meal, when new growth is starting to show. Clumps should be cut back to within 6″ of the ground at this time, and can be divided if needed.

You’ll love the look ornamental grasses can give your landscape, and these easy-care plants can be effective at many functions in many different types of landscapes. Give them a try today!

There’s an unfounded rumor that raspberries are difficult to prune. This isn’t true if you understand the type of raspberry in your garden. Summer-bearing raspberries produce only one harvest per year while everbearing, or fall-bearing, raspberries can produce two harvests.

Raspberry Types

Summer-bearing raspberries plants bear fruit on one type of cane, a floricane. These large, thick canes grow fruiting lateral branches. Most of the purple and black raspberry varieties and some red varieties are summer-bearing plants.

Everbearing raspberries grow two types of fruiting canes, floricanes and primocanes. The floricanes are similar those of the summer-bearing raspberry. However, the primocane has no lateral branches. Instead, the fruit buds are located on the thick cane. Most red and yellow raspberry varieties are everbearing.

No matter what type of raspberry you grow, proper pruning improves production and the taste of the fruit, the appearance of your garden and makes it easier to harvest the delicious fruit.

Raspberry Pruning Tips

If you are growing summer-bearing raspberries, you will follow a cycle of pruning out the older floricanes, which already bore fruit. If you are growing ever-bearing raspberries, you will prune out floricanes and the top one-third of the primocanes where fruit developed in the fall. However, you can choose a second option for pruning everbearing raspberries. Simply cut the entire plant to the ground in early spring to produce berries from fall until the first frost. This sacrifices the summer harvest, but puts all plant energy into fruit production for fall harvest, creating a larger, more robust crop. It also protects the canes from any extreme winter conditions and reduces insect damage. Using row covers or greenhouses to maintain a warmer temperature easily extends the harvest season later into the fall.

To simplify the pruning process…

When you grow your own berries, you know exactly how they were grown, you save money, and best of all, they taste great, even with dirt under your fingernails!

Tall or short, red, pink, purple, blue, white and shades in between, few shrubs provide the versatility of hydrangeas. Generations of gardeners have loved and designed their gardens using these showy shrubs as summer privacy screens, landscape focal points and beautiful cut flowers. Now, thanks to new hydrangea introductions, there are even more ways to use them.

Discover the Newest Hydrangeas

New types of hydrangeas are being introduced every year, and these showstoppers are fast favorites among both experienced hydrangea aficionados as well as newcomers to the hydrangea craze.

• ‘Endless Summer’
  Termed “the best new flowering shrub of the decade” by some gardeners, this cultivar has gained a reputation as the first “reblooming” hydrangea. Blooming from early summer to first frost on both new and old wood, it is unfazed by high heat or extreme cold. Now gardeners in colder microclimates can grow beautiful low maintenance 3-5’ tall and wide hydrangeas. The 8″ diameter mophead balls of light blue or pink flowers bloom the entire summer.

• ‘Bloomstruck’
  A dwarf ‘Endless Summer’ this hydrangea grows to only 2-4’ tall and wide with pink or blue 4-5″ diameter mopheads on upright red-purple stems. Perfect for containers, in smaller gardens or in the front of cutting beds, it also graces balconies and decks. In fall, red-purple colored leaves extend the beauty.

Color Tip: Change the flower colors of ‘Endless Summer’ and ‘Bloomstruck.’ The soil pH affects the flower color of many hydrangeas. To intensify the pink color, decrease the acidity by adding hydrated lime. To intensify the blue color, increase the acidity by adding sulfur. Our staff can suggest products to help you determine your soil pH and the amount of lime or sulfur to use.

• ‘Quickfire’
  Also known as Hydrangea paniculata, this variety blooms earlier than most other hydrangeas and has flowers along an elongated stalk. The flowers, blooming on new wood, open as white, gradually turning to pink in the summer and darker rose in the fall. The soil pH does not affect the flower color. As one of the hardiest hydrangeas, this beauty grows to 6′ tall in most soils, full sun or dappled shade and tolerates drought conditions.

• ‘Little Quickfire’
  A dwarf form of ‘Quickfire,’ this tiny powerhouse has all the beauty and benefits of its bigger relative but in a small package. Growing only to 3-4′ tall with a slightly larger spread, this hydrangea makes a big statement in a little space when covered with blooms and can be an ideal choice to start out with hydrangeas.

• ‘Bobo’
  Another paniculata hydrangea, this variety creates huge drama for such a little plant. Growing only to 3′ tall and wide, it’s a thriller in containers, and easily won the Gold Florall medal for best novelty plant. ‘Bobo’s early season white flowers also bloom on new wood and cover the plant on strong overhead stems. Unaffected by soil type or pH, this hardy hydrangea steals the show wherever it is planted.

No matter how you use these newcomers in your landscape – larger varieties in the back of beds or as borders, smaller options in the front or in containers – their long-lasting flowers will make you think summer truly is endless.

A simple water feature can make a large impact even in small spaces. The addition of a container water garden will transform, beautify and diversify your existing garden into an oasis that brings relief during the dog days of summer and beyond. Sit back, relax and enjoy the melodious sound of dancing water from your garden pond, and it will provide soothing, background music to your summer retreat. Bring wildlife into the garden by incorporating fish, frogs and snails into your mini aquascape. A simple water feature may be placed in the garden, on a deck, patio or porch or even added to a rooftop garden for a tremendous impact in a tiny space.

Choosing a Container

Container water gardens can be created from practically anything that has the capability of holding water or supporting a liner. Ceramic sinks or tubs, half-barrels, buckets, pottery or planters and troughs can all be used to create beautiful ponds. Remember, these features will look their best when the shape and materials are similar in style to that of your home and surrounding gardens.

Lining Your Container

If you have chosen a whiskey barrel or other similar wood container, follow these simple instructions to incorporate a liner to waterproof the container.

1. Center your flexible liner over the whiskey barrel or other container. Push down in the center so excess material is evenly spaced over the outside lip. Begin folding the liner over itself at 4 to 6 inch increments, working your way around the container and minimizing any bulges. Fasten each fold with a ½ inch staple placed about ½ inch from the top of the container.
2. Trim the liner so it is even with the lip of the barrel or container.
3. Fill your container with water, and then arrange your aquatic plants and pump/filter system.

Rigid pond liners are also available to insert into half whiskey barrels for ease of waterproofing these containers, but double check sizes to be sure you choose the right fit.

With such a wide assortment available, pots and planters make great garden ponds when properly prepared.

1. Plug the drainage hole with a small piece of pond liner spread with caulk.
2. Seal any minor cracks with caulk.
3. Paint the inside of the container with a water garden sealant.

Properly lined, your container will hold water easily without slow leaks that can traumatize plants and destroy your water garden.

Picking Plants

The use of aquatic plants will help you avoid the need for algaecides by reducing pond algae in two ways. First, aquatic plants remove excess phosphorus and nitrogen from the water. Second, plants shade the water from sunlight, thereby inhibiting algae growth. For a healthy balance, cover half of your pond surface with floating plants for shading. Submerged plants should be planted at a rate of one bunch, 6-10 plants, for every 5 square feet of surface area. Marginal or bog plants will complete the ecological balancing act.

• Floaters: Water Lettuce (Pistia stratiotes), Water Hyacinth (Eichhornia crassipes), Frogbit (Hydrocharis morsus-ranae) and Miniature Water Lilies (Nymphae spp.). These plants provide habitat and will shade the pond water surface to reduce the production of algae.
• Submerged Oxygenators: Anacharis (Elodea Canadensis), Water Buttercup (Ranunculus aquatilis) and Fanwort (Cambomba caroliniana) are great choices that help maintain water clarity by consuming excess nutrients that contribute to the production of algae. These plants can reproduce rapidly, but they are easily controlled in the small pond by simply removing surplus growth.
• Marginal Plants: Sweet Flag (Acorus spp.), Dwarf Cattail (Typha minima), Dwarf Papyrus (Cyperus profiler), Iris (Iris pseudacorus) and Camelion plant (Houttuynia cordata). Placed at a pond’s edge, these marginal aquatic plants add color, height and variation to the water garden. They also provide cover, habitat and oxygen.

Be careful not overwhelm your container water garden with too many plants or it will be difficult to maintain a natural balance.

Fish and Other Pond Life

Different types of wildlife will love to be a part of even a small water garden.

• Fish: Fish create additional interest to a water garden by adding sparkle and movement. Good choices for a small water garden are: Goldfish, Red Comets, Calico Fantails and Shubunkins. Do not overstock your water feature. As a rule of thumb, each inch of fish should have 6 square inches to one square foot of water.
• Snails: Slow and steady, snails can help keep your water garden clean and healthy. Japanese Trapdoor Snails eat algae stuck to the sides of the pond and will consume excess fish food.
• Tadpoles and Frogs: Tadpoles will morph into amusing frogs. Tadpoles eat algae and add motion and interest to the pond, especially for children. Frogs will lend sound to the garden and aid in insect control.

Water Garden Container Care

Several common problems can occur even in small water gardens, but they are easily controlled and you can keep your water garden looking beautiful.

• Algae: Despite all your planning, it is perfectly natural for your pond to turn green at first. Once the plants get to work, the green will fade. If you find that you require a little extra help in algae control, try Microbe-Lift or Barley Straw pellets, both are natural algae controls. Adding an extra snail or other algae-eater to the pond can also help control the color naturally.
• Mosquitoes: Mosquitoes may be managed in several ways. Adding water movement to the pond with a pump and small fountain will keep the insects from breeding or settling on the water. Adding BT (Bacillus thuringiensis) to the water in the form of Mosquito Dunks will also discourage the insects. Incorporate small fish into your pond garden, they eat mosquito larvae. Other mosquito predators include: dragonflies, bats, tadpoles and frogs, all of which can be a part of your backyard ecosystem.

Maintenance

Check the pond weekly. You need to be observant to animal activity and any abnormal growths or marks. Inspect plants and fish for health, insects or disease. Clean up any dead or yellowing foliage. Replace evaporated water as necessary. If your water contains chlorine or other chemicals, be sure they are removed before adding this water to your pond. Chlorine is toxic to fish and beneficial bacteria. Chlorine will dissipate after a few days if it is exposed to air, but do not add fish or plants until after this is accomplished.

With just a little thoughtful planning, the right plants and proper care, you can have a small water garden to brighten up a small space in your yard.
