What Are Coffee Trees, Flowers, and Cherries?

Ever wondered what a coffee cherry really looks like while sipping your morning espresso? Most coffee drinkers never see the plant behind their cup—yet understanding how coffee grows helps explain flavor, processing, and even why some beans cost more. This guide breaks down the whole coffee plant journey, from flower to fruit to the beans you roast.

A mature coffee tree typically grows 5–10 metres tall but is pruned to under 2 metres for easier harvesting. Each coffee cherry holds two beans, except rare single round beans called peaberries, which make up less than 5% of a harvest and are prized for their intense flavour.

What Is a Coffee Tree?

Coffee trees are evergreen shrubs or small trees that reach 5–10 metres in height in the wild. For easier picking, farmers prune them to stay under 2 metres. The tree produces oval, deep green fruits that ripen from green to bright red—earning the nickname 'coffee cherry' due to their cherry-like appearance. Inside each cherry are usually two flat-sided seeds: your everyday coffee beans.

What Do Coffee Flowers Look Like?

Coffee trees bloom after 4–5 years. Flowering occurs around February to March, with blooms lasting just 3–5 days. The white, five-petaled, star-shaped flowers resemble jasmine and emit a strong, sweet fragrance. They grow tightly along branches in clusters. These delicate flowers eventually give way to green coffee fruits, starting the long journey to ripeness.

How Do Coffee Cherries Develop and Ripen?

After flowering, green coffee fruits form. These immature fruits stay green for 6–7 months before ripening. When ready, the outer skin turns bright red, matching the appearance of cherries—hence the common name 'coffee cherry'. Beneath the red skin lies a layer of sweet, sticky mucilage, which encases the coffee beans inside a tough, tan-colored inner shell known as parchment. Each bean is coated with a thin, papery membrane called silverskin.

What Is a Peaberry and Why Is It Special?

Occasionally, a coffee cherry produces just one rounded bean instead of two. This is called a peaberry (or single bean), which lacks the usual flat side and is smaller and nearly round. Only a tiny fraction of cherries yield peaberries, so they must be hand-selected. Their concentrated shape is believed to intensify flavour, making peaberries highly sought-after and often more expensive than regular beans. Many coffee enthusiasts consider them the finest expression of a coffee lot.

Frequently Asked Questions

How tall do coffee trees usually grow?

Wild coffee trees can grow to 5–10 metres, but most are pruned to under 2 metres in commercial farms to make harvesting easier.

When do coffee trees flower?

Coffee trees begin flowering around 4–5 years old, usually from February to March. The flowers last only 3–5 days and closely resemble jasmine in both appearance and scent.

How long does it take for coffee cherries to ripen?

After the flowers fade, it takes roughly 6–7 months for the green coffee fruits to ripen and turn bright red, similar in colour to cherries.

What’s inside a coffee cherry?

Each red coffee cherry normally contains two flat-sided coffee beans surrounded by sweet mucilage, protected by a hard parchment layer, and each bean has a thin silverskin.

What is a peaberry coffee bean?

A peaberry is a rare, single round coffee bean that forms when only one bean develops inside a cherry instead of two. It’s smaller, rounder, and often has a more intense flavour, making it more valuable.
