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.
I have some peonies that I want to transplant but cannot plant them in their permanent place until next spring when our new house will be built. Can I dig them now and transplant them again next spring?

Is it possible to plant and grow Italian cypress in the Chicago area? Are our winters too severe for it? If they are, is there an alternative conifer that will provide a similar look?
