110+ Weed Riddles with Answers

This deck never fully decides which weed it means, and that's the point. One half is straight backyard trivia -- dandelion, crabgrass, kudzu, the taproot that regrows no matter how many times you pull it. The other half is cannabis culture vocabulary -- joint, grinder, budtender, terpenes -- and a handful of riddles deliberately use both meanings at once, daring you to guess the wrong garden. When this deck runs dry, the Boob riddles pick up right where these leave off.

Which Weed Is the Riddle Talking About

Check the setting before you answer. A clue about a lawn, a mower, or a flower bed points to an actual plant -- chickweed, bindweed, foxtail -- and wants the specific species, not just 'a weed.' A clue about a lighter, a dispensary, or a rolling tray is working the cannabis vocabulary instead, and wants terms like budtender or trichomes.

The riddles that mention both -- a grandmother pulling the same plant a dispensary sells by the gram -- are doing it on purpose, playing the word's two lives against each other for the punchline. A last group leans on slang phrases that mean one thing in a business meeting and another at a party: joint venture, grassroots campaign, green thumb. Those reward knowing both definitions, not just one.

Where This Deck Fits

The garden half works anywhere -- these read like a normal riddle set, fine for a classroom or a family road trip, since nothing in the plant vocabulary needs an adult audience or a second look.

The cannabis half is built for a different room: a game night with friends who'll get the budtender and 4:20 references without an explanation, or an adult group chat where a well-timed riddle beats another meme. Deal a garden one first to set someone up, then follow with the cannabis version of nearly the same clue and watch them catch the switch a beat too late.
