Question
This bright orange flower is growing in a roadside meadow in Harrisville, NH. It looks like Erysimum capitatum - but that is not supposed to occur here. Erysimum asperum can have "orangish" flowers, according to Marilyn Dwelley, but she says the plant is "ash-colored" and this is definitely not ash-colored.
Answer
Dear DavidBlair, good morning. The species in your photograph does look like Erysimum capitatum (sand-dune wallflower). But, to confirm this, we need a measurement of the petal length (including the narrow basal portion where it attaches to the receptable) and sepal length. Could you acquire these for me? If so, please email me at ahaines@nativeplanttrust.org so we can discuss further. This may be a new state record!
