Colombian Coffee Species: Plant Morphology Explained

When you sip a cup of Colombian coffee, you’re tasting fruit from a plant with very specific physical traits—traits that shape everything from yield to cup quality. But what does the actual coffee plant used in Colombia look like? If you’ve ever wondered why certain varieties thrive at high altitudes or how leaf shape ties into processing, the morphology holds answers.

Colombia’s primary coffee species is Coffea arabica, specifically the small-bean typica-related group. The plant typically grows as a small tree or large shrub, reaching 5–8 metres in height, with distinct leaves, flowers, and fruit structures that define its growth and productivity.

What Does the Colombian Coffee Plant Look Like?

The coffee plant used in Colombia is classified as a small tree or large shrub. It usually grows to a height of 5–8 metres, often branching heavily from the base. Older branches appear greyish-white with swollen nodes, while younger branches are smooth, flattened in cross-section, and free of hairs.

Leaf Structure and Physical Traits

The plant’s leaves are thin but leathery (thinly leathery), shaped either oval with pointed tips (ovate-lanceolate) or simply lance-shaped (lanceolate). They measure 6–14 cm in length and 3.5–5 cm in width. The leaf tip comes to a long, gradual point (long-acuminate), with the tapering section extending 10–15 mm. Leaf bases are wedge-shaped (cuneate) or slightly blunt, rarely rounded. Edges are smooth (entire), sometimes with shallow waves, and both leaf surfaces are hairless. On the underside, small pocket-like pits (areolar glands) may or may not appear in the vein axils. The central leaf vein (midrib) protrudes on both sides, with 7–13 side veins per side. Leaf stalks (petioles) range from 8–15 mm. Leaf-like appendages (stipules) are broadly triangular. Those on young upper branches have sharp, needle-like tips (acute or aristate), while older branches bear stipules with more abrupt points, measuring 3–6 mm long.

Flowers, Fruits, and Seed Structure

The coffee plant produces flowers in clusters called cymules, which form in leaf axils. Each cluster holds 2–5 individual flowers, which may sit on nearly non-existent stems or extremely short ones. The blooms are fragrant, with stalks (pedicels) around 0.5–1 mm long. Flower parts include two types of fused bracts (sepals): two broadly triangular and two narrowly lanceolate—each about twice as long as wide. The calyx tube is 2.5–3 mm long, and the calyx rim is either flat or faintly toothed. The flower’s corolla is white and 10–18 mm long, typically splitting into five lobes (rarely four or six). The lobes often extend beyond the tube and have blunt tips. Pollen-producing structures (anthers) stick out from the flower, measuring 6–8 mm, while the style is 12–14 mm with two stigma branches, each 3–4 mm long.

The fruit—or coffee cherry—ripens to a broad oval shape, turning bright red. Each cherry is 12–16 mm long and 10–12 mm wide, with a tough outer skin (exocarp) and sweet, fleshy middle layer (mesocarp). Inside, the seed (bean) has a curved, convex back and a flatter front with a longitudinal groove. Seeds measure 8–10 mm in length and 5–7 mm in diameter.

The main flowering period occurs between March and April.

Why These Traits Matter for Coffee Growing

The size, leaf arrangement, and fruit structure of the Colombian coffee plant directly influence how it’s cultivated, pruned, and harvested. Compact forms with strong branching (like those reaching just 5–8 metres) are easier to manage at high elevations. The specific leaf shape affects photosynthesis efficiency and drought tolerance. Meanwhile, cherry size and seed shape determine processing methods and roast profiles. Understanding these traits helps farmers select resilient varieties and roasters appreciate origin-specific qualities.

Which Coffee Varieties Are Grown in Colombia?

Though the article focuses on morphology, Colombia’s coffee landscape is dominated by arabica plants exhibiting these traits—especially varieties like Caturra and Typica (or Typica-related cultivars). These are the genetic basis for most plants in the country’s high-altitude regions, particularly in areas like Huila, where elevations exceed 1,500 metres. Such morphological consistency supports uniformity in cultivation and processing across the country’s renowned coffee-growing zones.

Frequently Asked Questions

What is the main coffee species grown in Colombia?

The primary coffee species grown in Colombia is Coffea arabica, specifically small-bean varieties related to Typica, including widely planted types like Caturra. These are the plants that define the country’s coffee morphology.

How tall does a typical Colombian coffee plant grow?

A standard Colombian coffee plant reaches a height of 5–8 metres. It usually develops multiple branches from the base, forming a compact yet tall shrub or small tree structure ideal for high-altitude cultivation.

What do the leaves of Colombian coffee plants look like?

The leaves are thinly leathery, shaped either oval with pointed tips (6–14 cm long, 3.5–5 cm wide) or lanceolate. They have long, gradual tips (10–15 mm), smooth edges, and are arranged without hairs on either surface. Leaf bases vary from wedge-shaped to slightly blunt, and leafstalks are 8–15 mm long.

What colour and size are Colombian coffee cherries?

Ripe Colombian coffee cherries are bright red, broadly oval, and measure 12–16 mm in length and 10–12 mm in width. They have a tough outer skin and sweet fleshy interior, enclosing the characteristic coffee seeds.

How does flower structure affect coffee plants in Colombia?

Colombian coffee plants produce fragrant white flowers (10–18 mm) with five petals (sometimes four or six) in small clusters. The flower structure—including long anthers (6–8 mm) and a prominent style—supports pollination and ultimately influences fruit and seed development in the country’s coffee-growing regions.
