What three dwarf shrubs do you think gardeners should know about and why?
Evelyn Fink, garden center manager at The Fields on Caton Farm, Inc., Crest Hill
Yuki Cherry deutzia, Kodiak Black diervilla and Little Henry itea should have a presence in everyone’s garden. They will work well complementing taller shrubs in mass plantings and as a focal point when planted individually. All of them grow in full sun to partial shade with sizes ranging from 1½-4 feet. The itea will also grow in full shade. The unique shape and flower of each plant combined with the rich burgundy to wine-red fall color make these must-haves for plant lovers.

The native Sugar Shack buttonbush (Cephalanthus occidentalis) thrives in wet heavy soils and clay. Fragrant pincushion-shaped white flowers attract pollinators. Red fruit in winter. Bobo is the best Hydrangea paniculata to date from Proven Winners. It is 2-3 feet tall and completely covered with long-lasting white flowers. The Low Scape Black Chokecherry (Aronia melanocarpa). Only 2 feet tall, tolerant of all soils; very cold tolerant. Profuse small white flowers in spring and dark purple fruit. Brilliant red/orange/ magenta fall leaves.
Jeff Schulz, owner, The Hidden Gardens, Willowbrook
My favorite dwarf shrubs have all-season interest and can be pruned to stay even smaller. Fothergillia gardenia (24-30 inches tall) is the smallest fothergillia cultivar. White flowers emerge in spring just before the leaves. Fall color is red, orange and yellow. Disease-free. Spilled Wine Weigelia (24-30 inches tall and wide) has dark purple leaves all summer if planted in full sun. Long-blooming pink flowers in spring, Deer resistant. Bobo hydrangea (30-36 inches tall and wide) produces loads of white flowers in mid- to late summer, changing to pink in fall. Flowers are held upright on strong stems and do not flop.
Besides mums, what are a few other plants you would recommend for containers for fall color?
Dwarf or miniature sunflowers add a bright, sunny pop of color to any container. Mix them with pink celosia, ornamental kale, dwarf ornamental grass and ornamental peppers for a special autumn arrangement. The kale is a great addition as the colors get brighter with colder temperatures. Ornamental pepper can also be taken in and kept as a houseplant through the winter months. Or use aster through October and plant in the garden before the soil freezes. Comes in many colors.
The rudbeckias ‘Indian Summer’, ‘Prairie Sun’ and ‘Becky Cinnamon Bicolor’ all have beautiful large flowers. Herbs and leafy vegetables like Swiss chard ‘Bright Lights’, mustard ‘Red Giant’, bronze-leaved fennel and variegated sage all add fun textures. Plectranthus ‘Mona Lavender’ combines nicely with ornamental kale and cabbage. Also plant trailing pansies like those in the ‘Cool Wave’ series at the edge of planters and hanging baskets. Another creative way to add interest to fall planters is with preserved and dried botanicals, sticks or accents.
Our favorite addition to autumn containers – hands down – is ornamental kale. As the temperatures drop, the leaf color intensifies and the plant actually becomes more attractive. We frequently pair ornamental kale with late season grasses as well as decorative gourds and squash tucked amongst the foliage to celebrate the abundance of the harvest season. Your visitors may still be enjoying your kale peeking through the early snow on Thanksgiving Day!
What trends do you see in container plantings, such as type of pot, materials, sun or shade, foliage or flowers.
Brenda Williams, Sales, Pesche’s Greenhouse, Floral & Gifts, Lake Geneva, Wisc.
As our lives get busier, gardeners are looking for easy care and double duty – plants with colorful or unique leaves. Like coleus.They come in all sizes from thrillers to fillers and even a spiller called ‘Rose Lava’ that tumbles over the edge. A tall nicotiana or canna lily easily substitutes for a spike in the center of a container. A euphorbia like ‘Diamond Frost’ might look delicate but is an excellent performer whose “flowers” are actually tiny white leaves.
I also see more succulent containers. With their diversity in texture, color and form plus low maintenance, they fit well in our busy lives. They are modern and bold.
Lori Harms, owner of Countryside Flower Shop, Nursery and Garden Center in Crystal Lake.
This year we saw a huge increase in holiday greens sales, selling over 100 more than the year before. Spruce tips were in short supply so we used multiple birch logs in assorted lengths to gain height for the focal point. Magnolia leaves, seeded eucalyptus, winterberry branches and juniper berries were used to highlight the containers, along with evergreen fillers. We added elegance with glittered and iced branches in natural, gold, white or red. We also created whimsical looks by adding snowman heads or larger millimeter balls with stars or hearts on sticks for splashes of color.
Tina Perkins, Manager, Winding Creek, Millbrook
We have recently seen a progression towards decorative ceramic pots for container planting. Customers use them for fairy gardens or succulents, which seem to be trending. Depending on the size of the pot, customers may use a mix of small indoor plants and succulents. Usually indoor plants can take lower light conditions or a porch location. Succulents have become more popular to use in containers as they generally require higher light conditions. Both types of plants like a lighter soil.
Miniature gardening is the rage. What enchanting miniature plants work well in a shaded area?
Many miniature plants grow in shade. Some unusual ones are the 6-inch tall Solomon’s seal (Polygonatum humile ‘Tom Thumb’), the 2-inch tall Ajuga reptans ‘Planet Zork’ and two cultivars of the very slow-growing conifer Cryptomeria japonica: ‘Koshyi’ and ‘Tenjan’. Or look for two European gingers, Asarum forlesii ‘Mercury’ and Asarum takaoi ‘Roundabout’, which are about 3 inches tall. Also: the maidenhair fern (Adiantum venustum), mosses and miniature hostas
The best and most obvious answer is miniature and small hostas. From the ever-expanding “mouse” series with ‘Holy Mouse Ears’, ‘Mighty Mouse’ and ‘Giantland Sunny Mouse’ to newbies such as ‘Mini Skirt’, ‘Ladybug’, ‘Baby Booties’ and ‘Little Starlet’… perfection! Add some grass-like carex such as ‘Beatlemania’ for texture, miniature Solomon’s seal (Polygonatum humile) and dwarf heucheras from the Little Cute series, and your garden fairies will be in heaven.
If you’re planting in the ground, these low-growing perennials will add interest and texture to your garden: Irish and Scotch moss (Sagina sublata and S. subulata ‘Aurea’ – best in part shade), brass buttons (Leptinella squalida) and miniature hostas. Add color with annuals such as polka dot plants (Hypoestes), ‘Strawberry Drop’ coleus and torenia. It’s important to add perennials and annuals into your garden for a longer season of color.
Now that bedding impatiens (I. walleriana) are not recommended because of impatiens downy mildew, what are three good annuals for shade?
Chris Williams, production manager, K&W Greenery, Janesville, Wisc.
I like New Guinea Impatiens. They make nice bushy plants that are full of large colorful flowers and are easy to grow. You also get a large color selection with New Guineas. The SunPatiens and Bounce impatiens are fairly new plants, and they are recommended for sun as well as shade. Then there’s coleus. Who doesn’t like its colorful foliage? Many varieties grow upright, but others also spread. Torenia, also known as wishbone flower, has trumpet-like flowers of white, yellow, rose and purple that cover nicely mounded, low-growing plants.
Karen Wedel, manager of the outdoor floral department, Wedel’s Nursery, Garden Center, Kalamazoo, Mich.
One of my favorites is begonia. Tuberous varieties have large colorful blooms; wax begonias are good for mass planting. I’m also a fan of the big leaf, 16-20 inch tall Whopper series with large waxy leaves and summer-long flowers.
Another idea is coleus and caladiums. They come in different foliage colors, work great in gardens and containers. They are both also easy-care.
Finally, torenia or wishbone flower, named for the small “wishbone” inside the mouth of the pink, yellow or blue-purple flowers. Blooms all summer. Some varieties will trail.
Kevin DeBoer, manager, Big John’s Farm Market and Greenhouse, Chicago Heights
My favorite is Dragon Wing begonias. They’re usually sold in 4½ inch pots or hanging baskets. At my house I removed them from the baskets, then planted them in the ground in full shade. They turned out awesome! Plain wax leaf begonias are also good.
In addition, I like coleus. They don’t produce flowers, but they have many different vibrant leaf colors. In full shade New Guinea Impatiens will flower sparingly, but if you put them in some sun, they will flower more.
We all seem to plant the basic herbs like basil, rosemary and parsley. What suggestions can you offer for more exotic herbs that I could add to my garden to spice things up both for cooking and adding interest/beauty to my landscape?
Ron Peterson, head grower, Milaegers Garden Center, Racine, Wisc.
I think lemon grass (Cymbopogon citratus) would be a good candidate for landscape interest and culinary use; it is even reported to have more mosquito control attributes than citronella. It is a warm season annual grass that grows quickly and is used in teas and Thai cooking to add a lemony flavor without the acidity of lemon juice. Stevia is a natural sweetener option for those trying to avoid added sugar. There is also a mint called Berries and Cream which merges peppermint with berry flavors for a unique twist on the traditional mint options.
Lisa Hilgenberg, horticulturist, Chicago Botanic Garden, Glencoe
Golden lemon thyme (Thymus x citriodorus) adds good citrus flavor to dishes and tea. The 8-inch tall cultivar ‘Aureus’ makes a good edging paired with Salvia officinalis ‘Icterina’. The chartreuse ‘Lime’ shines in dark garden corners.
Red shiso (Perilla frutescens) has frilly garnet red leaves, edible flowers and a spicy cinnamon/clover flavor. Papalo (Porophyllum ruderale) has a taste between arugula and cilantro. Plant once cilantro bolts to seed. Steely blue foliage up to 5 feet tall.
Joe Heidgen, co-owner, Shady Hill Gardens, Elburn
A plant that is often included with the popular herbs that gardeners know at Shady Hill is the scented geranium. It doesn’t look anything like a garden geranium, but it has a wide range of fragrances, as well as varying leaf shapes and colors. The fragrances may be lemon, rose, pine, ginger, lime, balsam or apple. It can be used in cooking and also in potpourri and sachets. Some scented geraniums are upright, some cascading, but all are unique and quite easy to grow. They are ideal for planters.
Kevin DeBoer, manager, Big John’s Farm Market, Chicago Heights
Onion or garlic chives can be grown and cut for use in potatoes and eggs. We also have five different types of mint that can be grown and used for mojito, flavoring water and teas. Some varieties such as pineapple mint are attractive and add beauty to the garden. Thymes such as English and lemon can be used in pasta and in marinades for grilling. A good marinade for meat can be made from thyme, rosemary, sage, Italian olive oil and pepper.
What are some trends in gardening you see becoming more prevalent in the next few years?
Current gardening trends continue to explore a variety of annual shade alternatives. Consider begonias of all types, such as fibrous, hiemalis, nonstop, rex, tuberous and the trademarked Big series and Dragon Wing. For a tropical feel, caladiums, elephant ears, and banana plants are not only exotic but add an element of height. Lastly, the hundreds of coleus varieties, along with black and chartreuse sweet potato vines, are colorful, reliable, and rich in texture.
I believe choosing plants for butterflies, bees and other pollinators will be an important trend in 2015 as folks realize the important role they play in our environment. Growing fruits and vegetables will also remain an important focus of gardeners, especially those that can be grown in containers and small spaces. Low-maintenance plants, preferred by both aging and beginning gardeners, will be another trend to watch in 2015.
People are looking for “bee-safe” plants that are free of neonicotinoids and other harsh pesticides. Also, they want to do vegetable gardening with non-GMO varieties. Succulents are very hot. The indoor use of succulents in dish gardens is a no-brainer; they look cool, they’re so easy to care for and make great unique gifts. Ornamental kale and cabbage have become very popular for fall decorating.
The popularity of hostas has made gardeners realize how much fun it is to use foliage for color, so they are looking beyond flowers to the reds and purples of coral bells (Heuchera); the yellow fall bottlebrushes of Amsonia hubrichtii; and the great fall colors of shrubs such as Viburnum, oakleaf hydrangeas (H. quercifolia), witch hazel (Hamamelis) and trees such as seven son flower, (Hepticodium), Ginkgo and scarlet oak (Quercus coccinea).
I applied commercial compost and hardwood mulch to an area where I am establishing a small garden. I did a few soil tests on the area and the results indicated the nitrogen was depleted. I intend to spread a bag of dried blood to rectify this problem When is the best time to apply the dried blood?
I’d like to know the secret to growing a decent-sized pumpkin for jack-o-lanterns for the grandkids and for decorating. My experience in recent years is that they get about as big as a basketball and then begin to rot. What am I doing wrong?
I thought that purple coneflowers were insect proof, but now I see some aphids at the bud and tiny flies. What is wrong?
