Perennial, stemless, flowers lilac and blue. Sandy or gravelly soil, dry fields and hillsides. Maine to Minnesota, south to Florida and Missouri. Rare in northern Ohio. April, May.
Short, vertical.
Numerous, nearly orbicular in outline but separated into three or five divisions, and the side divisions often two to three-parted; divisions linear or narrowly spatulate, sometimes toothed or cut at the apex.
Large, an inch wide, pale or deep lilac, purple, or blue, rarely white. Var. bi-color, the two upper petals deep violet, the others paler. Occurs sparingly at the north, most common southward.
An exceedingly beautiful Violet, occurring sparingly throughout our northern range but common southward; in early spring it appears abundantly in the markets of Washington and Baltimore. The variety bi-color is strikingly handsome with the two upper petals deep violet and velvety in texture, the other petals paler blue. This is the southern form.

Bird's-Foot Violet. Viola pedata
Viola sagittata
Perennial, stemless, flowers dark violet-blue, rarely white. Wet meadows and marshes. Maine to Michigan, south to Georgia and Texas. Found in northern Ohio, but not frequent. April, May.

Arrow-Leaved Violet. Viola sagittate
Stout and fleshy.
Varying from oblong heart-shaped to halberd-shaped, arrow-shaped, oblong, lanceolate or ovate, toothed more or less; petioles varying from short and margined to long and naked.
Deep violet-blue with darker lines, rather large; lateral petals bearded; spur short and thick.
The Arrow-Leaved Violet may be recognized by its leaves, of which it has a variable collection, but they are so alike in their unlikeness that this is a personal characteristic; they are rarely like arrow-heads, oftener like the bowl of a teaspoon with the handle broadened at the bowl. In addition to the deep violet-blue blossoms the plant also produces cleis-togamous flowers.
