A friend of mine plants an apple tree every year in her backyard in the highlands. Every winter she has an apple story to tell — new varieties she’s tried, weird historical trivia she picked up from apple growing forums, or something surprising she read about apple genetics. Last Christmas she casually mentioned that apples are technically members of the rose family. I thought she was joking. She wasn’t.
That single fact sent me down a research spiral, and I came out with a list of apple facts so strange that they don’t feel real. But they are.
Why Apples Are More Fascinating Than You Think
We eat apples so often that we stop seeing them as anything special. They’re just — apples. Round, familiar, in every supermarket. But dig even a little into the science, history, and biology of this fruit and you find things that sound made up. Here are fifteen of the strangest apple facts I’ve come across, and none of them will disappoint you.
#1: Apples Are Related to Roses
The Rosaceae Family Connection
Apples belong to the Rosaceae family — the same botanical family as roses. Look closely at an apple blossom in spring and you’ll see the resemblance. Five petals arranged in a symmetric pattern, similar structure, similar flower architecture. The family relationship isn’t just visual — it’s genetic.
Other Rose Family Members
The Rosaceae family also includes pears, peaches, plums, cherries, apricots, strawberries, raspberries, and almonds. If you grow any of these in your garden, you’re basically running a rose family reunion. That’s why many of these plants are affected by similar diseases and pests — they share evolutionary history and susceptibilities.
#2: Apples Float in Water
The Science Behind Apple Buoyancy
Drop an apple in water and it floats. That’s not by accident — it’s why apple bobbing works as a traditional game at Halloween parties in Western cultures. If apples sank, the whole tradition would be impossible.
25% Air Content Explained
An apple is approximately 25% air by volume. Tiny pockets of air trapped inside the flesh give the fruit enough buoyancy to float. This is also why apples feel lighter than they look — you’re holding a fruit that’s mostly water and air with some fiber structure holding it together.
#3: Apple Seeds Contain Cyanide
Amygdalin Explained
Apple seeds contain amygdalin, a compound that releases cyanide when metabolized by the body. This is a genuine, verifiable fact — not internet myth.
How Much is Dangerous
Before you throw away your fruit bowl, the amounts are extremely small. You’d need to chew and swallow roughly 150 to 200 apple seeds to reach a potentially harmful cyanide dose. Swallowing a few seeds accidentally is completely harmless because the outer coating protects the amygdalin from being released.
Should You Worry?
No. Casual apple eating with occasional swallowed seeds poses zero risk. The seeds’ outer shell has to be broken through chewing for the amygdalin to convert to cyanide, and even then the amounts per seed are tiny.
#4: Over 7,500 Varieties Exist
How Many Can You Name?
Most people can name maybe 5 or 6 apple varieties — Gala, Fuji, Granny Smith, Red Delicious, Golden Delicious, Honeycrisp. There are over 7,500 known apple varieties in the world. Supermarkets carry a tiny fraction of what exists.
Rarest Apple Varieties
Some varieties exist in only a handful of orchards worldwide. The Black Diamond apple grown in Tibet is dark purple, almost black. Newton Wonder is a heritage English variety kept alive by a small number of dedicated growers. Api Etoile has a star-shaped cross-section.
Extinct Apple Varieties
Sadly, thousands of apple varieties have gone extinct over the past century due to industrial farming’s focus on a handful of commercial types. Heritage apple preservation societies work to save the remaining rare varieties from being lost forever.
#5: Apples Originated in Kazakhstan
The Wild Apple Forest
The wild ancestor of the modern apple — Malus sieversii — grows in the forests of Kazakhstan, specifically in the Tian Shan mountains near the city of Almaty. The name Almaty literally means “father of apples” in Kazakh.
How Apples Spread Worldwide
From Kazakhstan, apples traveled westward along ancient trade routes, spreading through Central Asia, the Middle East, Europe, and eventually to the Americas with European colonizers.
Silk Road Apple Journey
The Silk Road played a major role in apple distribution. Traders carrying apples across Asia introduced the fruit to new regions. Each new location produced local varieties as trees cross-pollinated with wild species and were selected by growers over generations.
#6: Apples Have More Genes Than Humans
Apple Genome Science
The apple genome contains approximately 57,000 genes. Humans have around 20,000 to 25,000 genes. Apples have more than double the genetic complexity of the humans eating them.
What This Means
More genes doesn’t mean apples are more complex organisms than humans — plant genomes have accumulated duplications over evolutionary time. But it does mean apple breeders and geneticists have an enormously complex biological system to work with when developing new varieties.
Apple DNA Research
Apple genome sequencing has helped scientists understand disease resistance, flavor development, and storage properties. This research directly benefits modern apple breeding programs producing better varieties for growers and consumers.
#7: Apple Trees Can Live 100+ Years
Oldest Apple Trees
The oldest known apple tree in North America is located in Vancouver, Washington. It was planted in 1826 and is still alive nearly 200 years later. Some heritage apple trees in Europe are documented as being over 300 years old.
Apple Tree Lifespan
Modern commercial apple trees on dwarfing rootstocks typically live 30 to 50 years before productivity declines. Heritage varieties on standard rootstocks can live and produce fruit for well over a century when properly maintained.
Famous Old Apple Trees
The Isaac Newton apple tree at Woolsthorpe Manor in England, believed to have inspired his gravity discovery, is still alive and producing fruit approximately 400 years after being planted. Grafted descendants of this tree have been planted in gardens worldwide.
#8: Apples Ripen Other Fruits
Ethylene Gas Science
Apples produce ethylene gas as they ripen. Ethylene is a natural plant hormone that triggers ripening in many other fruits. This is why apples stored near other fruits will speed up their ripening — sometimes helpfully, sometimes not.
How to Use This Trick
If you have hard, unripe stone fruit or pears, place them in a paper bag with an apple. The ethylene concentrates in the enclosed space and speeds ripening by 1 to 3 days. This is a genuinely useful kitchen trick that gardeners and home cooks use regularly.
Ripening Bananas with Apples
Green bananas placed in a paper bag with an apple ripen significantly faster than bananas left on the counter alone. It’s the same ethylene principle at work.
#9: Newton and the Apple Story
Is the Story True?
Yes and no. The famous story of an apple falling on Isaac Newton’s head is fictional. But there is a genuine historical event that the myth is based on.
What Really Happened
Newton observed an apple falling from a tree in his mother’s garden at Woolsthorpe Manor in 1666. This observation apparently prompted him to think about the invisible force that pulls objects toward the ground. He never claimed the apple hit his head — that embellishment came later.
The Real Apple Discovery
Newton’s observation of the falling apple contributed to his development of the law of universal gravitation. The tree he watched still stands and produces apples today, over 350 years later.
#10: Apple Company Has Nothing to Do with Apples
How Apple Got Its Name
Steve Jobs named the technology company after visiting an apple orchard while on a fruitarian diet. He liked that “Apple” would come before “Atari” in the phone book and thought the name sounded fun and non-intimidating.
The Logo Story
The famous bitten apple logo was designed by Rob Janoff in 1977. The bite in the apple was included partly to prevent people from mistaking it for a cherry or other round fruit.
Alan Turing Connection Theory
A popular theory suggests the bitten apple logo honors Alan Turing, the computer scientist who took his own life by eating a cyanide-laced apple. Both Apple co-founder Steve Wozniak and logo designer Rob Janoff have said this is not true, but the theory persists as internet folklore.
#11: Apples Were Used as Currency
Historical Apple Trade
In medieval Europe, apples and cider were significant enough trade goods to be used as forms of payment. Rents were sometimes paid in apples, and apple orchards were valuable property assets.
Johnny Appleseed Real Story
John Chapman, known as Johnny Appleseed in American folklore, was a real person who planted apple orchards across the American frontier in the early 1800s. What most people don’t know is that his apples were mostly bitter cider varieties used for making alcoholic cider — not the sweet eating apples the story usually implies.
Apple Economic History
Apples have been economically significant across many cultures. Cider production, apple export markets, and orchard land values have shaped rural economies in England, France, the United States, and beyond for centuries.
#12: The Most Expensive Apple in the World
Sekai Ichi Apple Facts
The Japanese Sekai Ichi apple — the name means “world’s number one” — sells for around $20 per apple. Individual premium specimens have sold for even more at auction.
Why It Costs So Much
Sekai Ichi apples are hand-pollinated, washed with honey, individually inspected, and packaged with care that resembles luxury goods. The result is a large, cosmetically perfect apple that Japanese consumers gift-wrap and present as high-end presents.
Other Premium Apple Varieties
Ruby Roman grapes and Densuke watermelons follow similar premium production models in Japan. Luxury fruit is a genuine market segment in Japanese culture, where fruit gifting is a serious tradition.
#13: Apple Mythology is Everywhere
Greek Mythology Apple Facts
The golden apple of discord — inscribed with “for the fairest” — sparked the Trojan War in Greek mythology. Hercules’s eleventh labor involved stealing golden apples from the Garden of the Hesperides.
Norse Mythology Apple Facts
In Norse mythology, the goddess Idunn kept golden apples that gave the gods eternal youth. When the apples were stolen, the gods began aging rapidly. The apples had to be recovered to restore the gods’ immortality.
Apple in Fairy Tales
Snow White’s poisoned apple. William Tell shooting an apple off his son’s head. The apple appears throughout Western fairy tales and folklore as a symbol of temptation, danger, and transformation.
Apple Forbidden Fruit Debate
The forbidden fruit in the Garden of Eden story is often depicted as an apple, but the Bible never specifies what fruit it was. The apple association came from medieval European art and literature, likely because the Latin word “malus” means both “apple” and “evil.”
#14: Apples Have Natural Wax
Natural vs Artificial Wax
Apples produce their own natural wax coating as they grow. This waxy layer protects the fruit from moisture loss and disease. When you wash an apple and it looks less shiny — you’ve removed some of the natural wax.
Why Apples Are Waxed
Commercial apples are often coated with additional food-grade wax after harvest to replace the natural wax lost during washing and to improve appearance and shelf life. Common commercial waxes include carnauba wax and shellac.
Is Apple Wax Safe?
Yes. Commercial apple wax coatings are approved as food-safe. If you prefer to avoid them, wash the apple thoroughly with warm water and a soft cloth, or choose organic apples which typically use minimal or no wax coating.
#15: The Fear of Apples is Real
Malusdomesticaphobia
Malusdomesticaphobia is the technical term for a genuine, documented fear of apples. It’s rare but real. Sufferers may experience anxiety at the sight, smell, or touch of apples.
Other Unusual Apple Phobias
Related conditions include fears of apple seeds specifically, fear of apple trees, and general fear of fruit (fructophobia).
Apple Related Conditions
Some people have oral allergy syndrome that causes itching or tingling in the mouth when eating fresh apples. This is often related to birch pollen allergy — the proteins in apples resemble birch pollen proteins closely enough to trigger a reaction. Cooking apples usually eliminates the reaction.

FAQs About Apple Facts
Do all apple seeds contain cyanide?
Yes, but in extremely small amounts. Swallowing a few whole seeds is harmless because the outer coating prevents the amygdalin from breaking down.
How many apple varieties are grown commercially?
Only about 100 varieties are grown commercially at any scale, though 7,500+ exist worldwide.
Can I grow an apple tree from a supermarket apple seed?
Yes, but the resulting tree won’t produce fruit identical to the parent. Apples don’t grow “true from seed” — you’ll get a genetically unique tree that may or may not produce good fruit.
Why do apples turn brown when cut?
Enzymes in the flesh react with oxygen when exposed to air. Lemon juice or vitamin C slows this reaction because it’s acidic and provides antioxidants that block the browning.
Are apples native to America?
No. The only apple native to North America is the crabapple. All eating apples were brought to North America by European colonizers starting in the 1600s.
What’s the healthiest apple color?
All colors offer nutritional benefits. Red apples contain more antioxidants in their skin. Green apples typically have slightly fewer sugars. Eating a variety gives you the widest nutritional benefit.
Final Thoughts
That friend of mine still keeps planting new apple varieties every year. Last visit, she showed me a tree that produces apples with pink flesh — a heritage variety she’d tracked down through a specialist nursery. It’s the kind of thing that most people never realize exists. The world of apples is much bigger, weirder, and more fascinating than the six varieties in your local supermarket ever suggested.
Next time you eat an apple, remember — you’re holding a fruit that traveled from Kazakhstan mountains, is related to roses, has more genes than you do, contains a tiny amount of natural cyanide in its seeds, and probably came from a tree that will still be standing when you’re long gone.
Not bad for something you can hold in one hand.
