What are your three favorite “all-but-forgotten” perennials that every garden should include? Why do you like them?
Anemone tomentosa ‘Robustissima’ is a late season plant for sun to part shade and a wide range of soils. Deer and rabbit resistant with few pests or diseases. The fuzzy texture and gray-green leaves of Stachys byzantina ‘Helene von Stein’ complement other sun plants wonderfully. Leaves mask brown lower foliage of asters. The 3 to 5-foot tall Baptista australis and PRAIRIEBLUES cultivars offer gorgeous blue and purple flowers and they attract butterflies. They like full to part shade and tolerate poor soils.
My three favorite forgotten perennials are plumbago, bergenia and Stokes’ aster. Plumbago (Ceratostigma plumbaginoides) is a ground cover with sky blue flowers in fall and red leaves. Intersperse it with spring bulbs for three seasons of interest. Bergenia (Bergenia cordifolia) is versatile, handling conditions from moist sunny areas to dry shade. It is rabbit and deer resistant. When you rub your two fingers on either side of the leaf you can make it squeak (hence another common name: pig squeak). The long-blooming and easy-care Stokes’ aster (Stokesia laevis) is fairly pest and disease free. Rabbits tend not to eat it, and it attracts butterflies.
Three favorites of ours are pasque flower (Pulsatilla vulgaris), Laddie peony (Paeonia peregrina) and balloon flower (Platycodon grandiflorus). Pasque flower blooms very early in spring with extremely soft leaves and silvery green buds. Red, white or purple flowers; purple seems to have more vigor. The ferny-leaved Laddie peony also blooms very early with red flowers. It’s a hybrid of Paeonia peregrina and P. tenuifolia. Balloon flower is named for blue, pink or white flowers that start out looking like a balloon and open to look like a star. They have a long blooming period in summer.
What trends do you see in container plantings, such as type of pot, materials, sun or shade, foliage or flowers.

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.

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.
What plants do you predict will be best sellers this year? Why?
Bryon Angerman, nursery manager, Alsip Home & Garden, St. John, Ind. and Frankfort, Ill.
I believe these two compact hydrangeas will be hot plants this year. First is Invincibelle Wee White® hydrangea, a compact and reblooming white variety of ‘Annabelle’ hydrangea. Its dwarf habit of 18-24 inches and versatile adaptability to full-sun to part-shade planting locations will yield three to four months of continuous flowers on sturdy stems. It’s sure to become a staple in every landscape. Also look for Mini Mauvette hydrangea for similar habits with pinkish purple flowers.

Hydrangea Little Quick Fire will be a best seller this year. It blooms early with pure white flowers turning to pink, then rose. Its more
compact size, at 4-5 feet and fits into most urban gardens better than most other panicle hydrangeas. Hosta ‘Autumn Frost’ is an attention grabbing plant with powder blue leaves and showy yellow margins. Last year’s Perennial of the Year, Asclepias tuberosa, should continue to be a big seller because of its gorgeous orange flowers and because it is a host for monarch caterpillars.

Being at a retail garden center and nursery, I get to hear customers’ requests and questions about plants for their gardens. Being on the board of the Perennial Plant Association for 6 years, I get to hear hybridizers and growers claims about the “BEST” plants. It is wonderful when the claims of the hybridizers and growers match the requests of the gardeners and designers. The other fact that is worth stating is that the plants are trialed much better than in the past, so there is proof from many areas of the country that the recommended plants will perform and survive.
The first plant that I expect to be a good seller is one that has been selected by the members of the Perennial Plant Association as the Perennial Plant of the Year for 2018. It is Allium ‘Millenium’. Allium ‘Millenium’ is one of the very best ornamental onions. Unlike spring-blooming Allium bulbs, this hybrid Allium blooms in mid to late summer with large large 2 inch rose-purple, globe-shaped flowers over shiny deep green strappy, grassy foliage. Mature plants have dozens of globes covering this perennial plant. Allium ‘Millenium’ attracts butterflies and bees love it as well, but deer and rabbits stay away. This Allium is good for winter hardiness Zones 5-9; prefers full sun to part shade and is 10-12 inches tall.
second plant is a flowering perennial Echinacea. It is Echinacea KISMET™ Raspberry and it is different due to sheer flower number and a fabulous habit. It blooms first year, early in the season, with large flowers and continues until a hard frost. It is a great plant! I saw it in trials in the Chicago area and in Colorado. It attracts butterflies and hummingbirds. It is a wonderful cut flower with a great fragrance. It is deer resistant. It is hardy from Zone 4 to zone 10. It forms an upright mound that is 16 inches tall by 24 inches wide, up to 18 inches in flower. It is a beautiful hot pink color that blooms June, July, August, September and October. And, it likes average well drained soil in full sun.
The third plant is a hybrid of a native grass. Native plants are one of the strongest trends in gardening these days. The natural beauty of native Blue Grama Grass is raised to a higher level in Bouteloua gracilis ‘Blonde Ambition’. Its allure includes an abundance of horizontal seed heads, which resemble elegant, petite flags. They emerge chartreuse and transform to blonde. These exquisite blooms hover above thin, blue-green, two-foot stems. ‘Blonde Ambition’ was named a 2011 Plant Select® Winner for its resistance to pests, exceptional performance in low water conditions, retail appeal, and long-lasting attractiveness in gardens and containers. It pops right back up after snowfall. Bouteloua gracilis‘ Blonde Ambition’ was discovered and introduced by David Salman of High Country Gardens. It is easily grown in average, dry to medium, well-drained soils in full sun. It tolerates a wide range of soils, except poorly-drained, wet ones. It is hardy from Zone 3 to Zone 10. It is a tufted, warm season, Missouri native grass noted for its distinctive arrangement of mosquito larvae-like seed spikes which hang from only one side of its flowering stems. It is native to prairies, plains, open rocky woodlands and along railroad tracks. It has narrow, bluish-gray leaf blades (to 1/4 inch wide) that typically form a dense clump growing 12-15 inches tall. Foliage turns golden brown in autumn, sometimes also developing interesting hues of orange and red. Inflorescences of blond colored flowers appear on arching stems above the foliage in early to mid-summer, typically bringing the total height of the clump to 20 inches tall.
All three of these should be at the top of the selling lists for the 2018.
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.
Mark Maradik, plant manager, Pasquesi Home & Gardens, Lake Bluff
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.
I have read that purple coneflowers (Echinacea) are a good source of food for birds in the winter. Will they be okay if not trimmed back until spring? If so, how early should they be trimmed?
I have a large variegated sedum with pink flowers that I have had for years. I noticed that it has started to send up some all-green shoots. Why is it doing this and how can I keep my plant variegated?
What happens if I miss an issue?
