Roses, Apples, and Strawberries Walk Into a Family
Apples, cherries, strawberries, almonds, and roses are all in the same family. Broccoli, cauliflower, kale, cabbage, and Brussels sprouts are all the same species — just selectively bred into wildly different forms.
Plant taxonomy under the APG IV system, built on DNA analysis, reveals relationships that looking at leaves and flowers never could. The deepest split in flowering plants — monocots vs. eudicots — happened 130 million years ago. Monocots include grasses, orchids, and palms. Eudicots cover roses, oaks, sunflowers, and cacti.
246 species from mosses to orchids. Many plants once grouped by flower shape turn out to be unrelated, while species that look nothing alike share recent ancestors. Your kitchen, garden, and local park are full of secret relatives.
Did you know?
- *Broccoli, cauliflower, kale, cabbage, and Brussels sprouts are all the same species — Brassica oleracea — bred into different forms.
- *Strawberries, apples, and almonds all belong to the rose family (Rosaceae).
- *Orchids are the largest family of flowering plants, with over 28,000 known species.
- *Grasses (Poaceae) cover about 40% of Earth's land surface, making them the most ecologically dominant plant family.
- *Cashews and mangoes are in the same family (Anacardiaceae), which also includes poison ivy.
What is GuessKin?
GuessKin is a free daily guessing game built on real-world taxonomy. Choose from over 20 categories and try to identify the mystery plant. Each guess reveals how closely related your answer is to the target through a shared classification tree.
How does it work?
Every plant in GuessKin sits on a taxonomy tree — a branching hierarchy that shows how things are classified and related. When you make a guess, the game shows you the nearest common ancestor between your guess and the answer. The closer that ancestor is to the answer, the warmer you are. The tree visualization grows with each guess, narrowing down where the answer lives and helping you triangulate.
How to get the best score
- •Fewer guesses is better. The ideal game is guessing it in 1. Every guess counts against your score.
- •Speed matters too. The timer starts on your first guess. Quick, confident answers are rewarded.
- •Read the tree. Each guess gives you real taxonomic information. Pay attention to which branch the answer is on and which branches you've already ruled out.
- •Start broad, then narrow. Your first guess splits the tree. Pick something that gives you maximum information, then drill into the revealed branch.
Each GuessKin category uses a real classification system. These aren't made-up groupings — they're the same systems scientists and specialists actually use. New categories are added regularly. Every category is free, with no accounts and no ads.
