Plant Common Name

Dirigo Arubutus Moss Phlox, Moss Phlox

General Description

Cool lavender-blue flowers with darker eyes blanket the pretty moss phlox, 'Dirigo Arbutus', in late spring. This vigorous evergreen perennial is very hardy and has a low, broadly spreading habit.

Moss phlox is a native of eastern North America that naturally grows in open, rocky locations. It has very fine, needle-like leaves of moss green and produces hundreds of five-petaled tubular flowers in spring to early summer. These have incised petals and attract butterflies.

Sun-loving and vigorous, moss phlox prefers very well-drained, average soil. It looks super planted along stone walls, border edges or in rock gardens. Over time, 'Dirigo Arbutus' can spread to great widths, so it is wise to plant it where it can freely grow and spread.
