To identify this white wildflower in Maine, look for small white flowers on branching stems.
Each petal is deeply notched, so it might look like there are eight petals instead of four on every flower. The green leaves are covered with gray hairs.
Although bees, wasps, and other insects will eat Hoary Alyssum pollen, you’re better off killing this weed before it takes over your property. It can survive cold winters and hot summers. In addition, it thrives in poor soils and spreads prolifically, making it incredibly difficult to eradicate.
#7. Wild Calla
- Calla palustris
Also known as: Water Arum, Water-dragon, Swamp Lily, Marsh Calla
Growing Information
- USDA Hardiness Zone: 2-6a
- Life Cycle: Perennial
- Approximate Mature Size: 6-16 in (15-41 cm) tall
