Mahjong Flower Tiles Explained: How Flowers Work in American Mahjong
Quick answer: A standard American mahjong set has 8 flower tiles, and in American mahjong they are all interchangeable. The artwork, numbers and season names printed on them do not matter: any flower counts as any other flower. Flowers are regular tiles that hands on the card ask for (shown as F), not bonus tiles. You can pass them in the Charleston, call a discarded flower to complete a group of three or more (or to declare Mah Jongg), and use jokers in flower groups of three or more, but never in a single flower or a flower pair.
Flowers confuse new players because no two sets draw them the same way: one has peonies and orchids, another has bouquets, and an older set may have four flowers plus four seasons with numbers in the corner. Here is how flower tiles work in American mahjong, how they differ in Chinese mahjong, and how to pick them out of a new set.
What Are Flower Tiles in Mahjong?
Flower tiles are a separate type of tile, like winds or dragons. They belong to no suit, so they never count as a Bam, Crak or Dot, and they can never fill a gap in a run of numbers. In American mahjong they are working tiles: certain hands on the National Mah Jongg League (NMJL) card include flowers, written as the letter F, and you collect them just like any other tile in your hand.
That is the big difference from many Chinese styles, where flowers are bonus tiles set aside for points.
How Many Flower Tiles Are in a Mahjong Set?
There are 8 flowers in an American mahjong set. The full game uses 152 tiles:
- 108 suit tiles (Bams, Craks and Dots, 1 to 9, four of each)
- 16 winds (North, East, West, South)
- 12 dragons (red, green and white)
- 8 flowers
- 8 jokers
Many sets add spare blank tiles, which is why 160-tile sets are common. The Amber Tortoiseshell set, for example, lists 160 tiles: 152 game tiles plus 8 blank spares, including 8 Flowers and 8 Jokers. For the full breakdown, see our guide to how many tiles are in an American mahjong set.
Do Mahjong Flowers Have to Match?
No. In American mahjong all eight flowers are identical for play. A pair of flowers can be any two of the eight, and a pung of flowers is any three. The Gilded Obsidian set above shows why this matters: its eight botanical flower tiles each show a different bouquet, yet every one of them is simply "a flower" at the table.
What about seasons and numbers?
Some sets include four flower tiles and four season tiles (spring, summer, autumn and winter), and some print a number from 1 to 4 or a short season word in the corner. In American mahjong those details are decoration only. If a tile belongs to the flower group, it is a flower, whatever is painted on it.
American Mahjong Flower Rules
How flowers appear on the card
On the card, F stands for a flower, FF for a pair of flowers, FFF for a pung, and so on. Each line states how many flowers it needs. Because a set has eight flowers, a quint of flowers (five) can even be built without a joker, which is not possible with suit tiles, winds or dragons, since there are only four of each.

Passing flowers in the Charleston
Flowers can be passed in the Charleston like any other tile. Jokers are the only tiles that can never be passed. Whether you keep a flower is a strategy call, not a rule; our Charleston strategy guide covers how to decide.
Calling a discarded flower
You may call the most recent discard if it is a flower and it completes an exposed group of three or more flowers. You may also call a flower if it is the last tile you need to declare Mah Jongg. You cannot call a discarded flower just to make a single or a pair during play.
Jokers and flowers
Jokers can stand in for flowers inside a group of three or more, such as a pung or kong of flowers. A single flower and both tiles of a flower pair must be real flower tiles. If someone exposes a flower group that contains a joker, you can swap in a real flower on your turn and take the joker, just as with any other exposure. Our article on how jokers work in American mahjong explains joker exchanges in full.
Drawing a flower
In American mahjong, drawing a flower is just a normal draw. You add it to your rack and carry on with your turn. There is no replacement draw for flowers.
Flowers in American vs Chinese Mahjong
If you learned on a Chinese-style set, the flower rules can look contradictory. Here is the short version:
| American mahjong | Many Chinese and Hong Kong styles | |
|---|---|---|
| Number of flowers | 8, all interchangeable | Usually 4 flowers plus 4 seasons |
| Role | Regular tiles that card hands ask for | Bonus tiles that can add to your score |
| When drawn | Kept in your hand like any tile | Set aside face up and replaced with a new tile from the wall |
| Numbers on the tiles | Ignored | Often linked to the seats at the table |
| Jokers | 8 jokers can fill flower groups of three or more | No jokers in a traditional set |
That last row is why a Chinese set will not work for the American game without adding jokers. Read more in our comparison of American and Chinese mahjong.
How to Spot the Flowers in a New Set
Designer sets love floral artwork, so flowers are not always the only tiles with flowers on them. On the Amber Vine set above, the Dots are drawn as little blossoms, but each one carries a number from 1 to 9. The eight flower tiles in the bottom row have no number at all. A few quick checks help when you open a new set:
- Look for the corner number. Suit tiles are numbered 1 to 9. In many American sets the flowers carry no number, and when they do, it only runs from 1 to 4.
- Count to eight. Every suit tile, wind and dragon comes in fours. If you have a group of eight tiles that do not match anything else, those are your flowers.
- Do not mistake the 1 Bam. The 1 Bam is often a bird, such as the peacock 1 Bam on the Amber Vine and Gilded Obsidian sets. It has a 1 on it and belongs to the Bam suit.
- Set aside the blanks. Blank tiles are spares, not flowers. Keep them out of the game unless your group plays with a blanks house rule.
Our American mahjong glossary covers the other tile names you will see on the card.
Should You Keep or Pass Your Flowers?
A lone flower can look useless, but any flower matches any other, so it is easier to pair than a single suit tile. Keep it while you are still choosing a hand, then pass it in the Charleston if none of your target lines use flowers. When another player exposes flowers, count how many are left before you hold out for your own.
Choosing a Set With Flower Tiles You Love
Because the rules ignore what is printed on flowers, they are where designers have the most fun. A few sets with distinctive flower artwork:
- Amber Vine: 160 acrylic tiles with amber and copper flake backs, floral-vine suits and blue winds with small blossoms. Tiles only.
- Gilded Obsidian: 160 acrylic tiles with black and gold marble backs, bear and panda jokers and botanical flower tiles. Tiles only.
- Bloom Garden: 160 acrylic tiles in a lavender and lime palette with engraved flower-bloom faces, plus 4 pushers and a luxury storage case.
- Amber Tortoiseshell: 160 single-layer tiles with a tortoiseshell look, including 8 Flowers and 8 Jokers.
To finish a floral table, the Hunter Green Daffodil mahjong mat is a 33" x 33" neoprene mat with vintage botanical daffodils and an instructional layout printed on it, and the Clear Acrylic racks and pushers (set of 4, attached pushers) let colorful tiles show through. You can compare more options in our mahjong sets, mahjong mats and racks and pushers collections.
Mahjong Flower Tiles FAQ
How many flower tiles are in a mahjong set?
A standard American mahjong set has 8 flower tiles. They are part of the 152 tiles used in play, along with 108 suit tiles, 16 winds, 12 dragons and 8 jokers. Chinese-style sets also usually include 8 flowers and seasons, but no jokers.
Do mahjong flowers have to match?
No. In American mahjong all 8 flowers are interchangeable, so any two flowers make a pair and any three make a pung. The pictures, numbers and season names printed on them do not matter.
Are seasons and flowers the same in mahjong?
In American mahjong, yes. If your set has four flower tiles and four season tiles, all eight count as flowers. In many Chinese and Hong Kong styles they are treated as separate bonus tiles.
Can you call a flower in American mahjong?
Yes, but only the most recent discard, and only to complete an exposed group of three or more flowers, or as the final tile that completes your hand for Mah Jongg. You cannot call a discarded flower to make a single or a pair.
Can jokers be used for flowers in mahjong?
Yes, in a group of three or more flowers, such as a pung or kong. A joker can never stand in for a single flower or for either tile of a flower pair.
Can you pass flowers in the Charleston?
Yes. Flowers can be passed in the Charleston like any other tile. Jokers are the only tiles you can never pass.
