1. Dandelion
Ah, the classic dandelion! This cheerful little weed is probably the most well-known of the bunch, and for good reason. Those bright yellow flowers pop up in lawns and gardens everywhere, often before you even realize spring has sprung.
Dandelions have a distinctive fluffy seed head, which kids love to blow on, making a wish as the seeds float away.
But they’re more than just a pretty face! Dandelions are edible too! From root to flower, they’re packed with nutrients and can be used in salads, teas, and even wines.
