This is a very fragrant native woodland phlox with powder-blue flowers in spring. Reaching only 1 foot tall, it can spread to almost 2 feet and makes an attractive groundcover under shrubs or planted with other spring-blooming wildflowers. Leaves are semi-evergreen and hairy; stems root along their length. The blue flowers are salverform with petal lobes. This plant attracts hummingbirds and butterflies.

Gracefully arching 2 to 3-foot tall burgundy stems support narrow leaves streaked in pure white. From late spring to early summer, this species bears white flowers that mature into spherical black fruit in autumn, when the foliage turns a golden yellow. Variegated Solomon's seal is a fine choice for a shady bed. -Matt Griswold, Regional Picks: Northeast, Fine Gardening issue #27

Convallaria majalis Convallaria majalis
(Lily of the Valley, May bells)

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Lily of the valley's bell-shaped, sweetly scented flowers bloom in early spring. It likes partial to full shade and is perfect for a woodland garden. It may not be the best choice for your beds and borders because it tends to spread, but it is a perfect ground cover if you have a large shady spot under some trees.
