What does milkweed mean?
Milkweed refers to a type of perennial plant known for its milky sap and its role as a vital food source for monarch butterfly caterpillars. The most common species is Asclepias syriaca, often found in North American meadows and gardens. Milkweed plants are characterized by their clusters of small, fragrant flowers and their ability to thrive in a variety of conditions.
