(Browallia americana)
bro-WAL-ee-ah ah-mer-ih-KAY-nah
Synonyms:  Browallia elata
Genus:  Browallia
This plant produces distinct, 2-inch blossoms primarily in rich blue (but also in shades of purple and white), with dark eyes smudged white. It is suitable for sun and partial shade.
Noteworthy Characteristics:  A tender perennial from tropical South America, it will self-sow, but almost too late to produce flowers for the season. In fertile soil, it will amount to a large, airy mass of long-blooming and stunning blue flowers that may require staking.
Care:  Grow in fertile, well-drained soil in full sun to half shade.
Propagation:  Sow seed in early spring for summer-flowering plants.
Problems:  Aphids, white fly, tomato spotted wilt virus, fungal leaf spots.
