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.

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!

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.
