Field Notes
While looking around Limestone, Maine for our science class, we found a patch of purple flowers with an average of 5 petals on square, hairy stems in a developed area of town. Upon further examination, we saw that this plant had smooth edged, lance-shaped leaves of approximately 5.5 centimeters in either an opposite or whirled arrangement. This fits the description of the Purple Loostrife, an invasive species.

Comments

Sorry for the delay in responding. Well done MSSMBlueTeam. Your pictures, description and account leave no doubt that there is loosestrife way up there in Limestone.

I hope the plant you cut with the flower spikes did not go elsewhere. This plant is very prolific and you could accidentally spread this invasive without meaning to.

Great work BlueTeam.
