Geranium phaeum - Mourning Widow Geranium


SHADE PERENNIALS & THEIR COMPANIONS - 3


Shade has finally come into its own as a garden environment. And a wonderful place it is for any of the shade-lovers below or on the two previous pages of perennials, ornamental grasses and bulbs that prefer the coolness of a shady bower. Plant them with the recommended companions for extra emphasis.

POLYGONATUM

                    A plant with "presence", Solomon's Seal can be used as described on the following page.

                  • white Solomon's Seal
                  • Solomon's Seal with variegated foliage

                  • PULMONARIA

                    Lovely Lungwort will enchant in spring with often spotted foliage and variously-coloured nodding flowers. Some forms have blooms that start out pink, then change to blue. Other forms have flowers whose colour remains consistently white, pink, blue or red. If your plants go dormant early, your soil is too dry. Move them into evenly moist conditions in partial to full shade.

                    Pulmonaria:  Lungwort, Bethlehem Sage

                      Pulmonaria

                                  combined with:  Delphinium elatum 'Blue Connecticut Yankee' & Liatris spicata (rosy-purple)
                                A more subtle perennial than most, the Lungwort can be found in other forms at the link below.

                              • pink Pulmonaria
                              • Pulmonaria with silver foliage
                              • Pulmonaria with variegated foliage

                              • RANUNCULUS

                                Let the word "fast-spreading" forewarn you about this perennial for partial shade. Keep it out of your formal gardens and put it with companions that aren't apt to be overcome by its aggressively creeping nature.

                                Ranunculus repens:  Buttercup, 18-24" tall

                                  with:  ferns, Hosta
                                Try the link below for more ideas.

                              • yellow Ranunculus

                              • RODGERSIA

                                Magnificent Rodgersia, also known as Roger's Flower, is a bold foliage perennial that demands consistently moist to wet soil. If you possess such conditions, such as a bog or water garden, consider this plant. Its airy plumes when in bloom are a sight not available to those of us with mostly sunny and dry gardens.

                                Rodgersia:  Rodgersia, Roger's Flower

                                  where:  bog and water gardens, along streams, in dappled shade of high trees
                                    with:  Iris x germanica
                                      with:  water-loving Iris, Filipendula, Trollius, Astilbe, Hosta, Primula, ferns
                                        with:  Ligularia stenocephala 'The Rocket'


                                      SMILACINA

                                      Another perennial for shade that has arching leaf-clothed stems is Solomon's Plume, or False Solomon's Seal. Sometimes known also as False Spikenard, Solomon's Zigzag and Treacleberry, this spring-blooming native wildflower prefers neutral to acidic soil in light to full shade, although bloom will be better with some sun. Correct pronunciation for this genus can be either smye-luh-SEE-nuh or smye-luh-SIGH-nuh.

                                      Smilacina:  Solomon's Plume, False Solomon's Seal, 2-4' tall

                                        where:  light to full shade, under trees and flowering shrubs
                                          with woodland plants:  ferns, Epimedium, wildflowers
                                            with:  Aquilegia, Hosta, Dicentra, Pulmonaria

                                        • TIARELLA

                                          Foamflower, or Allegheny Foamflower, provides wonderful fuzzy spring flowers on stalks rising out of somewhat heart-shaped foliage. If your soil is slightly acidic, so much the better since this is what they prefer. Try this plant soon. You won't be disappointed.

                                          Tiarella cordifolia:  Allegheny Foamflower, 6-10"x12" tall

                                                      with:  Anemone blanda, Asarum canadense, Dicentra, x Heucherella, Iris cristata 'Abbey's Violet' (the best blue form)
                                                        combined with:  Trillium (white), Polemonium reptans & Phlox divaricata
                                                          in light shade with:  Iris x germanica

                                                        I love this perennial! It will delight you as well in its many forms. Check out the link below for more.
