There are many non-native plants at the preserve, due to its long history as a working farm as well as natural and human-caused disturbances. Only a few of them are invasive, growing so strongly that they displace many plants that would otherwise grow here. Here are two plants that are blooming at the preserve right now that are from Europe. They're not species we've tried to control; they may be weed pests in some places but they occur only occasionally here. Birdsfoot trefoil (Lotus corniculatus) is blooming in the turfgrass of some of the trails, and along a drainage ditch at the edge of a field. It gets its name from the shape of the flower. And we have both yellow- and white-flowered examples of moth mullein (Verbascum blattaria) growing in the parking lot meadow. The common name refers to the fuzzy filaments on the anthers of the flowers; they look like moth antennae. This is a biennial species—each plant lives two years. The first year it is inconspicuous as a basal rosette; in the second year it sends up the flower spike.
