Polygonatum biflorum var. commutatum 2019 Perennial Plant of the Year
Common Name: Great Solomon’s Seal
The delicate white flowers of the great Solomon’s seal bloom from late May to early June in Calgary, creating a spectacular show in any shade garden. Blue-black berries appear in the fall, and the plant turns a golden yellow in October. Clumps of this tall variety accent ferns and hostas and are excellent for cutting. Great Solomon’s seal is also deer and rabbit resistant and attractive to butterflies. Plants spread by rhizomes to form care-free colonies when in ideal growing conditions. When clumps are large enough, dividing may be done in early spring, just as the new growth emerges, or in early fall, before cold weather sets in. You won’t regret planting this showstopper.
Trumpet gentian forms a low slow-spreading carpet of pointed green leaves bearing spectacular large up-facing blue flowers. Performs best in a rock garden where the roots can stay cool and moist. Can be a challenge to grow in Calgary.
