Corsican Mint ~ Wonderful, mat forming groundcover that features tight green, aromatic foliage. Tiny lavender flowers in summer. Plant as a lawn substitution or between stones so that the gentle scent of mint is released when walked on. Excellent for front entryways and back patios. Will take moist areas as well as normal landscape scenarios and will reseed easily in the garden.
Lily of the Valley: These fragrant beauties have a tough-as-nails constitution that shrugs off bone-chilling temperatures. Plus, lily-of-the-valley is shade tolerant, making it a great groundcover for wooded backyards. Most commonly seen with white flowers, there are also varieties with pretty pink blooms. There’s also a variegated form with dark green leaves with white stripes. This plant is hardy to Zone 3. And they are deer resistant.
