Rainy Side Notes
A choice plant for between pavers is the charming blue star creeper, sometimes sold as Laurentia fluviatilis or Isotoma fluviatilis, from Australia. This semi-evergreen, tiny leaf plant cloaks itself with small, sky-blue, star-shaped flowers from late spring into summer, and continues with a sprinkling of blossoms for the rest of the season into fall. My favorite cultivar is Laurentia ‘Deep Blue’ with its darker blue flowers that don’t look washed out when growing close to other brightly hued flowers.
This ground cover gives a clean look between pavers, since it doesn’t creep over stones. Its requirements are well-drained soil and full sun for best results. Its downside is it will creep around the garden and overtake smaller plants. Site it carefully where it can romp around, adding spectacular affects in your garden.
