Description

Solomon Seal (Polygonatum sp.) is a very large genus of perennials comprising dozens of species. Many of the species that are appropriate for garden use in Kansas are native to seasonally dry to moist forests in North America and Asia. New growth arises each year from a finger-like slowly spreading rhizome system. The foliage has a central stem with architecturally arranged opposite leaves covering the length of the stem gradually getting smaller towards the end. Small bell-shaped white flowers appear in early spring followed by bluish-purple fruit. Flowers and new spring growth is frost-hardy. Most Solomon seals do well with average garden soils and moisture with many tolerating dry-shade well. Solomon's seal can grow for many years increasing in density without ever needing division. Over time this creates a nearly weed-proof groundcover. in eastern Kansas with 40 inches of rain per year on average, there seems to be plenty of moisture to create extremely healthy patches of Solomon seal that compete well with tree roots. While some species can tolerate sun, there are many better choices as sunburning will likely occur with afternoon sun in temperatures over 95 degrees F. Combine with hostas or other shade plants to create a dramatic effect. Included in our "edibles" database but depends on how hungry you are! Polygonatum biflorum, also known as Smooth solomon's-seal, is native to Kansas and Central U.S. forests in average to moist conditions including dry-shade. It adds a bright splash of light green to the shade garden. Fruiting does occur and desirable self-seeding occurs within the patch. Plants reach heights of 18-24" tall in Kansas. Fall color is a brilliant yellow for a week before going dormant. Maintenance is easy as stems easily detach when raking with fall clean-up. If cosmetic foliage leaf-rust is a problem, just cut back early. During the April deep freeze of 2007, temperatures bottomed out at 18°F after an extra warm March. Hosta and Solomon seal foliage had completely unfurled and was flowering. All hostas were killed to the ground but solomon seal foliage and flowers survived un-damaged! A great "Once it's there, it's there forever" plant for dry-shade!
