Dragons Ridge Solomon’s Seal Raised ridge ‘Koryu’ with ighter green stripes down the middle of each leaf makes this Solomon’s seal very different. Easy growing in moist woodland soil. Creamy, green tipped dangling flowers in spring. Low growing, arching foliage to about 16″. Easy and something different for the woodland garden. As with most Solomon’s Seal will make a nice patch over time. We have found most Polygonatums will increase much better given some morning or a bit of afternoon sun. In deep shade the spreading habit is reduced. Hardy zones 4-9
