Violet Family

Viola cucullata

Viola papilionacea

Common Blue Violet (Viola sororia). Ubiquitous in lawns, and there are some unaccountably dour types who try to eradicate it. Violets cause no harm; they never grow too high and are easily mowed, and they give us flowers like these. If you see a purple to pale blue violet in a neglected place, and especially if you see large numbers of them, this is probably the species.

Viola hirsutula

Viola fimbriatula

Viola sagittata

Viola triloba

Viola blanda

Viola pensylvanica

Viola canadensis

Viola striata

Johnny Jump-Up (Viola tricolor). This is the original Pansy, still so called in many places; it is every bit as colorful as our garden pansies, but smaller. It often escapes from plantings, and can occasionally establish itself in sidewalk cracks or vacant lots. Although it is associated with spring, it can bloom occasionally throughout the year
