Like yellow primroses, in whose family they actually are, the fringed loosestrife flowers open in midsummer when hot sun and dry wind might wither more delicate flowers. But fringed loosestrife, in the river-bottom woods and along railroad tracks where the ditches are damp, blossoms in duly and seems well able to survive the summer.

Fringed Loosestrife.

Lysimachia ciliata L.

July. River woods.

The plant is tall, often three feet high or more, with pairs of opposite, yellow-green, tapering leaves all along the branching stalk. Along the upper half of the stem there are flower stalks and branches which spring from the axils of the leaves, with slender, curving stems bearing oval, tapering buds. These open as five-petaled, pale yellow flowers with a pale red blotch at the base of each, petal. There are five curving stiff stamens and the pistil, and five recurved, sharp-pointed sepals cupping the flower.

Although fringed loosestrife has a tall, lank plant, the flowers nevertheless have some of the quality of spring blossoms. The upper part of the plant is a spring-flowering plant; the lower half is more like a summer weed. Perennials, they grow in the heavy rich ground of the river bottoms where they bloom abundantly during most of July.
