Tropical Plant Identification

Primary Markers for Identifying Tropical Plants Manually

It’s easy to get confused, wondering, “What tropical plant do I have?" The key is in knowing what to look for. There are three main features: leaf shape, growth habit, and foliage patterns, which are essential for correct and quick recognition. 

Let’s dive a little deeper into what you should pay attention to in each of the three categories, both for indoor and outdoor species.

Leaf Shape

A simple leaf type makes up ⅘ of all tropical plants compared to ⅕ of the compound type. But the detailed leaf classification distinguishes over 70 types of leaf shapes. Yet, the most common are:

• Oval — those are classical egg-shaped leaves, like in a Ficus elastica.
• Lanceolate — typically a sleek and spear-tipped leaf structure, similar to a peace lily.
• Obovate — such a leaf is narrow at the base and wide at the top. Crotons are a good example.
• Elliptical — these are often compared to a football shape. A popular representative is Zamioculcas zamiifolia.
• Spatulate — those leaves have a big violin-shaped structure, like in a fiddle leaf fig.
• Cordate — another common name is a heart-shaped leaf, such as in a heartleaf philodendron.
• Oblanceolate — these are usually leaflets that are narrow at the stem and widen toward the tips, like in an umbrella tree. 
• Obcordate — such a leaf is heart-shaped but attached to the stem by a pointed end. A common example is a false shamrock.
• Oblong — those are paddle-like, rectangular leaves, the same as in a bird of paradise.
• Linear — that’s a ribbon-like, long leaf, like in a Chlorophytum comosum. 
• Peltate — leaves of this type have a perfectly round shape, as in a Pilea peperomioides. 
• Cuneate — those are wedge-shaped, as you can find in a bird's nest fern.  
• Reniform — an interesting, curved kidney shape of leaves, like those of a rex begonia.
• Hastate — looks like a sharp arrowhead, same as in the Syngonium podophyllum.

Shape is the most important part of tropical plant identification by leaf, but leaf veins can also hold a lot of information. They are most commonly divided into pinnate, netted, and palmate.

Growth Habit

There are 11 common types of growth habits that are recognized in tropical plants:

• Climbing — these plants use aerial roots to climb up to the light. A common example is a pink princess philodendron.
• Clump-forming — that’s when a tropical plant sprouts multiple stems from a tight central base. The bushy clumps of elephant ears are a good representation of this type.
• Dense — this growth habit is ideal for privacy screens, as branches and foliage are very tight together. For example, a weeping fig usually creates a dense canopy that looks like there’s no space in it.
• Erect — this is a habit of growing straight up, as snake plants do. Usually, there’s no slouching if the plant is healthy.
• Mat-forming — as the name suggests, these species form a live carpet. For example, Fittonia albivenis often stretches tightly across the soil.
• Mound-forming — with such a growth habit, plants expand upward and outward, like flamingo lilies.
• Open — this style of growth often leaves a lot of space between the branches, as in Dracaena marginata with its bare trunk and big leaves.
• Prostrate — such plants will trail along the soil unless they have something to climb on. A common example is a golden pothos that can grow in any direction.
• Scandent — such tropical plants as bougainvilleas don’t have any true climbing tools, but they still manage to lean and weave around any steadier neighbor.
• Spreading — this growth habit means spreading in all directions, like a Chlorophytum comosum often does.
• Stemless — that’s when a plant doesn’t have a trunk or stalk, and all the leaves appear from a single central point. A good example is a bird’s nest fern.

Also, there’s another growth form classification that divides plants into:

• Tree — those are plants that have a permanent woody trunk, like a rubber tree that grows to the ceiling indoors and forms an umbrella of leaves.
• Shrub — plants, like tropical hibiscus, are smaller than trees and have multiple woody stems.
• Subshrub — species, like coleus, combine a woody base and soft, green growth at the tips. Their appearance can vary depending on the season.
• Herb — tropical plants of this type have completely soft, green stems. An example of a herb type is a Musa.
• Epiphyte — plants like moth orchids grow in the air instead of soil. They perch on branches or the bark of larger trees.
• Climber — those are shape shifters that use tendrils, aerial roots, and twining stems to grow vertically. For example, Syngonium usually starts as a bushy clump, but then it shoots vines with tiny roots to climb walls, trees, and other objects.

Tropical regions have high biodiversity, which has led to research and, consequently, different classifications. Both options we chose are popular and reliable sources of information used for the correct identification of tropical plants.

Foliage Patterns

The pattern of leaves, also known as phyllotaxy, is an excellent final point in the diagnostic check. Here are the most common types:

• Alternate — that’s like the foliage of plants, like rubber trees and golden pothos, which has a zigzagging rhythm. It means that in this pattern, each leaf pops a bit higher and on the opposite side of the last one.
• Opposite — in this pattern, leaves grow in pairs that are directly across from each other on the same level. Examples of this pattern include Fittonia albivenis and Coleus.
• Whorled — leaves of this pattern grow outward in tight, circular collars. Some examples of the whorled type are beetle pepperomias and oleanders.

Also, fenestration is quite common for tropical plants. It naturally occurs in the Swiss cheese plant. And the drip tips of leaves are typical for tropical species, as they help to shed water rapidly.
