Adorable sky blue star shaped flowers bloom from late spring through summer. The medium green rounded leaves form a dense 2-3” mat and will creep between stepping stones or along a garden path. Tolerant of heavy foot traffic and a variety of moisture levels and soil types, it is ideal for use as a small area lawn replacement or planted around spring bulbs. Plant 10” apart.
