Like its namesake, Mexican Petunia blossoms are quite similar to the annual petunia, but the two are unrelated. Lavender-blue flowers present themselves in mid-spring and continuously emerge until cold winter weather. Though the foliage appears lustrous and delicate, this shrubby plant can thrive in a variety of conditions and requires little to no care. It is a vigorous grower, and does well in pots that keep its spread contained. Plant form and flowering potential is dependent on how much sun it gets. Plant in full sun to encourage more blossoms and shrubbiness. Pair with New Gold Lantana or Arizona Yellow Bells for a dramatic color contrast.
