Growing Salvia seed is so rewarding. The butterflies and hummingbirds will love your garden when you grow these beauties! Woodland Sage plants are heavy blooming, tall and give a spectacular display of color. They feature multiple spikes of blue flowers over a long season starting in late spring and lasting through autumn. Leaves are long and toothed, soft green nearly silver in color, especially the undersides. They are great as a border plant, container plant, or as a cut flower for fresh or dried bouquets. The plants are tender perennials that are commonly grown as annuals in most cold winter areas.
