How Coffee Trees Grow: From Flower to Cherry

If you’ve ever wondered how your morning coffee bean began its life, the journey starts high in the branches of a tropical evergreen. The coffee tree isn’t just a pretty plant—it’s the entire origin story of your espresso, pour-over, and cold brew. But how does it grow, flower, and produce those iconic red ‘cherries’? Here’s the full breakdown of what really happens on the coffee farm before roasting even begins.

In short: A mature coffee tree grows white, jasmine-like flowers that bloom for just 3–5 days, then forms green elliptical fruits. Over 6–7 months, these ripen into bright red ‘cherries,’ each typically holding two flat-sided beans—but sometimes just one round peaberry, prized for its concentrated flavor.

What Does a Coffee Tree Actually Look Like?

Coffee trees are evergreen shrubs or small trees native to tropical climates. Under natural conditions, they can reach heights of 5 to 10 metres. However, most commercial coffee farms prune them down to under 2 metres to make harvesting easier. The leaves are dark green and glossy, providing a lush canopy under which the coffee cherries grow.

The Coffee Flowering Stage

A coffee tree typically begins flowering when it reaches 4 to 5 years of age. Flowering occurs around February to March. The coffee blossoms are small, white, and strongly fragrant, with five petals that curve backward. Each flower grows in tight clusters along the branches, closely resembling jasmine or gardenias in both appearance and scent. However, the blossoms last only 3 to 5 days, making the sight of a full coffee blossom bloom a fleeting but spectacular event.

From Flower to Coffee Cherry

After the flowers fade, the tree begins developing green, oval-shaped fruits. These immature coffee fruits are hard and deep green. Over the next 6 to 7 months, they gradually mature, turning from green to a vivid red when fully ripe. Because of their color and shape, these fruits are commonly called ‘coffee cherries.’ Beneath the bright red skin lies a layer of sweet, sticky mucilage, followed by a tough, protective parchment layer. Inside that, each cherry usually holds two coffee beans, lying flat against each other with a thin layer of silvery tissue—called the silver skin—covering each bean.

What Is a Peaberry and Why Is It Special?

Occasionally, a coffee cherry develops only one round bean instead of the usual two. This single, rounded bean is called a peaberry (or sometimes ‘caracol’). Unlike regular flat beans, peaberries are almost perfectly spherical, with no flat side. They occur in very small quantities and must be hand-sorted, which adds to their cost. Many coffee enthusiasts believe peaberries have a more intense and concentrated flavor due to their rounded shape, which allows for more even roasting and development. While not common, peaberries are often considered a specialty-grade treat.

Frequently Asked Questions

How tall does a coffee tree get?

A coffee tree can naturally grow to between 5 and 10 metres tall, but on commercial farms it is usually pruned to stay under 2 metres to simplify harvesting.

What do coffee flowers look like?

Coffee flowers are small, white, and have five backward-curving petals. They bloom in tight clusters on the branches and emit a strong, sweet fragrance similar to jasmine. The flowers last only 3 to 5 days.

How long does it take for coffee cherries to ripen?

It takes approximately 6 to 7 months for coffee cherries to ripen from green to their final bright red color after the flowers have bloomed.

What is a coffee cherry?

A coffee cherry is the fruit of the coffee tree. It starts green, turns red when ripe, and usually contains two coffee beans. The outer skin is red and juicy, followed by a layer of mucilage, a protective parchment layer, and the beans themselves, each covered with a thin silver skin.

Why are peaberries more expensive?

Peaberries are rarer because they form when only one rounded bean develops inside a coffee cherry instead of two flat ones. They must be hand-selected and are often considered to have a more intense flavor, leading to higher prices.

Do all coffee cherries have two beans?

No, most have two flat beans, but a small percentage contain a single round bean known as a peaberry, which occurs naturally and is separated during sorting.
