Polygala sanguinea L.

Field milkwort, blood milkwort, purple milkwort

About plant names...

Field milkwort is a North American native plant. These plants do well in sandy or rocky soils with low nutritional content, in both dry or moist conditions.

Plants: 3-16" (7.6-40 cm) in height, with a hairless stem, although it may look pock-marked and irregular near the top from flowers that have dropped away. A cross-section of the stem resembles the keel of a ship or has four sharply-defined edges. The thin taproot smells a bit like wintergreen.

Leaves: Linear or narrowly elliptic, attached directly to the stem (sessile) or via very short stems, up to 1" (3 cm) × ¹/₁₆-⅛" (2-5 mm). They may be either alternate or opposite.

Flowers: A compact raceme atop each stem, which may be purplish-pink, rose-colored, white, or pale green. The coloring comes from enlarged sepals called “wings.” The entire flowerhead is up to ¾" (2 cm) tall and about ⅜" (1 cm) around. They appear from May to October.

Fruits: Each tiny flower becomes a tiny capsule with two hairy seeds.

Individual flowers are bilaterally symmetrical, and consist of two “wings,” which are actually sepals; and a smaller yellow corolla, the true flower. There are also three more sepals and three petals, but they are too small to see in this view. · 12/12/2020 · Bemis Rd Conservation Area, Pepperell, Mass­a­chu­setts
