Plant Combinations: Garden Phlox ‘Laura’ (Phlox paniculata ‘Laura’) and Rue (Ruta graveolens)

phlox Laura  rueThe fine delicate foliage of the rue appears in the spring adding a lovely blue green color to the garden. It is followed later in the summer by the purple-blue flowers of the garden phlox ‘Laura’ that echo the blue of the rue leaves. At summer’s end the phlox fades but the foliage of the rue remains until frost. Both plants thrive in full sun and moist but well-drained soil.

Dead heading will prolong the bloom time and mulch will keep the roots cool and happy. The foliage is mildew resistant, but watering early in the day is recommended for maximum protection against the fungus.
