Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Ground cover for shady slope in Illinois
Answered by: Nan Hampton

QUESTION:

Dear Mr. Smarty: I have a shady sloping area that I am trying to cover with low fast growing, perennials that will keep maintenance to the minimum and prevent erosion. Grass would be very difficult to cut. Non invasive please.

ANSWER:

Ferns are the first plant to come to mind and there are several evergreen ones—Polystichum acrostichoides (Christmas fern), Dryopteris marginalis (marginal woodfern), Asplenium platyneuron (ebony spleenwort), and Polypodium virginianum (rock polypody).  Here is more information about the Christmas fern, marginal shield fernebony spleenwort, and rock or common polypody. All these ferns are generally less than 2 feet high.

Another suggestion for an evergreen plant is Lycopodium digitatum (fan clubmoss).  A synonym for the botanical name is Diphasiastrum digitatum and here is more information about it.  It grows to only about 1 foot, but may be difficult to establish.

You can see our list of Illinois Recommended natives that are commercially available and suitable for landscaping.  If you use the NARROW YOUR SEARCH option in the sidebar you can limit the list to plants that grow in the shade by choosing 'Shade...' under LIGHT REQUIREMENTS.   You can also use other criteria to limit the list even more.  Here are a few possibilities from that list.  None of these are evergreen.

Aquilegia canadensis (red columbine)

Arisaema triphyllum (Jack in the pulpit)

Asarum canadense (Canadian wildginger)

Campanula rotundifolia (bluebell bellflower)

Dicentra cucullaria (dutchman's breeches)

Maianthemum racemosum ssp. racemosum (feathery false lily of the valley)

Mertensia virginica (Virginia bluebells)

Polygonatum biflorum (smooth Solomon's seal)

Podophyllum peltatum (mayapple)

Uvularia grandiflora (largeflower bellwort)

Uvularia sessilifolia (sessileleaf bellwort)

Here are photos from our Image Gallery of some of the plants above:
