Coffee, this everyday beverage, originates from the fruit of the coffee tree. This article begins with its botanical classification and systematically sorts out the origin, growth habits, and suitable cultivation regions of the coffee tree. The coffee tree belongs to the genus Coffea in the family Rubiaceae. It is an evergreen shrub and is naturally distributed in the "Coffee Belt" between the Tropic of Cancer and the Tropic of Capricorn. Besides commercial cultivation, the coffee tree can also be grown as an ornamental potted plant, displaying its unique charm in artificial environments. The article will explain in detail the coffee tree's growth cycle, pruning management, and planting applications in coffee shops, accompanied by multiple images to aid explanation, helping coffee enthusiasts understand this plant's natural and artificial cultivation points more comprehensively.

Coffee.

When "coffee" is mentioned, most people immediately think of that cup of beverage. And the source of the beverage "coffee" is precisely processed from coffee beans. So where do coffee beans come from? The path is as follows: coffee tree → (flowering, fruiting) → coffee fruit (also called coffee berry or coffee cherry) → (pulping and subsequent processing) → green coffee beans.

As a plant, the coffee tree's biological classification is as follows: → (Kingdom) Plantae → Angiosperms → Eudicots → Asterids → (Order) Gentianales → (Family) Rubiaceae → (Subfamily) Ixoroideae → (Tribe) Coffeeae → (Genus) Coffea

Beyond the "phylum, class, order, family, genus, species" classification framework learned in nine-year compulsory education, the hierarchy is actually divided more finely in practical application, so the above classification incorporates more subdivided names.

The coffee tree is an evergreen shrub. In natural environments, its height can reach 3 to 5 meters, and some varieties can even grow to 10 meters. In artificial cultivation scenarios, however, the plant is usually pruned to maintain a suitable height for ease of harvesting.

The core growing region of the coffee tree lies between the Tropic of Cancer and the Tropic of Capricorn. Globally, it is mainly concentrated along the equator in Central and South America, Africa, and Asia, forming a belt-shaped distribution area, the so-called "coffee belt," also known as the "coffee zone."

Generally speaking, a coffee tree needs to grow for 3 to 5 years before it begins to flower and fruit on a scale; with proper management, the harvest period can last for decades, and the period of highest economic value is usually considered to be around 10 years. After the golden harvest period, the coffee tree can be subjected to "cutback," retaining only a stump of 30 to 50 centimeters. Some believe that a coffee tree can only withstand two cutbacks in its lifetime; others say it can be done multiple times.

Ornamental plant: coffee

Many people wonder: apart from tropical regions, can coffee really not grow elsewhere?

Coffee is indeed native to the tropics. However, in many coffee shops, we often see lush green coffee trees, which are precisely coffee seedlings cultivated as ornamental plants.

Seeing these coffee seedlings growing in a foreign land, people will then ask: can these plants, having left the warm regions, still flower and fruit?

Nowadays, technology is advancing rapidly, and artificial environments can already simulate various climatic conditions. Even far from their native habitat, coffee plants can still grow quite well.

Not to mention botanical gardens, some coffee shops ingeniously use artificially grown coffee as a highlight to attract customers, while also regarding it as part of their own coffee atmosphere.

Of course, the purpose of artificial cultivation is not harvesting, but rather as an extension of coffee culture in coffee shops, and also a way for coffee enthusiasts to get close to and learn about coffee.

Figure 1: Coffee leaves are arranged oppositely, forming a cross-shaped opposite leaf arrangement.

Figure 2: After the leaves unfold, it can be seen more clearly. As they slowly grow, branches gradually sprout from the leaf axils.

Figure 3: Coffee branches are also opposite.

Figure 4: Coffee is a shrub. In the wild, it grows 3 to 5 meters tall, and some varieties can reach ten meters. Please pay attention to the trunk.
