Families are field shortcuts; lookalikes can still be dangerous

Crops, weeds, and ornamentals that share a family often share flower shape, fruit type, or chemistry. That helps you guess pollination, how a weed will spread, or whether sap might irritate. It does not make a roadside plant safe to eat.

Treat unknown umbels, milky saps, and ornamental seeds as not food until a local extension name is certain. Invasives that look pretty still take a bed.

If two plants look like cousins, ask before you graze, cook, or keep the pretty one.
