The Garlic Mustard wildflowers are growing all over Cape Cod. They look like a delicate, little wildflower with four 1/4″ white petals and 4 light green sepals, but when you research them, they are an invasive weed.

“Garlic mustard is an invasive non-native biennial herb that spreads by seed. Although edible for people, it is not eaten by local wildlife or insects. It is difficult to control once it has reached a site.  It grows 2-3 (up to 6) feet tall. Lower leaves are kidney-shaped with scalloped edges. This weed spreads by seed and can self-pollinate, helping it rapidly displace native plants along trails, in forests, and on riverbanks, among other areas.”

So, although it looks pretty, they are very invasive to native vegetation.
