Ruellia brittoniana (Mexican Petunia)

Ruellia brittoniana (Mexican Petunia) is a shrubby perennial boasting a profusion of petunia-like, vibrant lavender-blue flowers, 2 in. across (5 cm), from midsummer to fall. Borne solitary or in clusters at the tips of purplish stems, they rise above the foliage of lance-shaped, glossy green leaves. Very showy, they are attractive to butterflies, bees and other pollinators.
