The roadside daylily isn't a native plant. It appears with such frequency, however, that it is now appears to belong. Sadly, in some places it is quite invasive and difficult to get rid of. Hemerocallis fulva grows along roadsides, in ditches, near salt water, next to old foundations, and just about anywhere it pleases. Although it prefers full sun it will also perform admirably in shade. This massive grouping was found along a sheltered bay in Harpswell, Maine. The salty ocean was just a matter of fifteen feet away. These daylilies were thriving.
Recommended Plant: Thalictrum rochebrunianum. Flowering in summer, this meadow rue send up flower stalks that are 4-6'. The leaves of the plant stay closer to the ground. The leaves are similar to columbine and blue-green in color. It is apparently deer resistant as well, which makes it attractive in certain locations. This meadow rue does best in full sun and rich soil. It is best planted in groupings to create a mass of the airy flowers. One variety goes by the name "Lavender Mist" which is fitting, given the flowers.
