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.

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
