Common name:Dwarf Vinca or Periwinkle
Botanical name:Vinca minor

Periwinkle is a hardy, evergreen groundcover with glossy green leaves and cheery periwinkle blue or purple flowers in the spring. This plant is best suited to large areas and shrub borders, as it would overwhelm most perennials. Avoid its use along the riparian corridor or in urban/open space interfaces as it is aggressive and can escape, overtaking native plants. Easier to control in dry shade areas. Grows about 6 to 8 inches high, and spacing for planting purposes is about 2 to 3 feet, but its spread is indefinite.

Common name:Moss Sedum
Botanical name:Sedum acre

A perfect sedum for rock gardens and borders, Goldmoss sedum forms a carpet of soft green that becomes completely engulfed with yellow flowers in summer. Foliage turns a beautiful shade of red during cold months. Use among stepping stones, along a garden path, or in a parkstrip. Also nice in containers. Grows about 3 inches tall and spreads about 10 inches wide. It is a little brittle, and so is best with only light foot traffic.
