Browallia americana: Self-Sowing Annual with Blue Flowers

Browallia americana 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.
