From Schreiner’s catalog, 2017: BOUNDARY WATERS (Schreiner 2017) M. 35" $50.00. Harkening back to our state of origin (Minnesota, of course), Boundary Waters literally bubbles and surges like the network of waterways above Lake Superior. Beards, colored a slight yellow, barely counter the intense deep blue color saturation. Large flower petals impart a feeling of permanence. Who can resist a clump of this satisfying color in their garden? Dip your toe in our Boundary Waters in our photo at right. Seedling 2004 #155. |
