A comprehensive guide to plant identification from beginner to expert. Master the 5 key dimensions of observation and learn both traditional and smart identification methods to easily recognize every plant around you.
On a weekend park walk, have you ever been in a situation where your child pointed to a beautiful flower and curiously asked 'What flower is this?', but you could only give a vague answer? Or have you seen a unique plant in the wild and wanted to know if it's poisonous or what uses it has, but had no way to find out? According to the 'China Plant Enthusiasts Behavior Report,' over 78% of plant lovers have experienced the embarrassment of 'not recognizing plants' during daily observations, and 'plant identification' has also become one of the TOP 3 keywords in annual search volumes on major plant science platforms. Today, let's create a comprehensive plant identification guide to help you easily overcome the difficulty of 'recognizing flowers.'
To accurately identify plants, you first need to master the key dimensions for observing plants. These dimensions are like a plant's 'ID information,' helping us quickly narrow down the identification range.
Leaves are the most easily observed part of a plant, focusing mainly on shape (round, oval, lanceolate, etc.), edges (entire, serrated, wavy, etc.), veins (parallel veins, reticulate veins), and arrangement (alternate, opposite, whorled). For example, ginkgo leaves have a unique fan shape with irregular wavy notches on the edges, which is one of its most distinctive identification features.
The color, shape, number of petals, and inflorescence type (raceme, spike, capitulum, etc.) of flowers are important identification criteria. For instance, rose flowers are typically double-petaled with ruffled petal edges, while Chinese rose petals have relatively smooth edges, and Chinese rose stems have hooked thorns, whereas rose thorns are denser and smaller.
Different plants have vastly different fruit types, including common ones like berries (such as grapes), drupes (such as peaches), pods (such as soybeans), and nuts (such as walnuts). For example, dandelion fruits have white pappus, which disperses in the wind when mature - a very easily recognizable characteristic.
The texture of stems (woody, herbaceous), color, presence of thorns or hairs, and branching pattern can also help with identification. For instance, cactus stems are succulent with sharp spines on the surface, while bamboo stems are hollow with distinct nodes.
The growing environment of plants (such as forest, grassland, desert, waterside, rock crevices, etc.) and growth habits (such as sun-loving, shade-tolerant, drought-resistant, moisture-loving) are also important supplementary identification information. For example, water lilies can only grow in water, while cacti are suitable for growing in arid desert environments.
With the development of technology, plant identification methods are becoming increasingly diverse, and we can choose appropriate methods based on our own situation.
Authoritative plant field guides and books are 'classic tools' for plant identification. For example, 'Chinese Advanced Plant Atlas' and 'Flora of China' etc., these books detail morphological characteristics, distribution areas, and other information of plants in various parts of our country, with clear pictures, suitable for plant enthusiasts with some botanical background. When using them, you can search step by step according to the previously observed plant characteristics in the field guide's classification directory (such as by plant family and genus).
If you encounter plants that are difficult to identify, you can consult botany teachers, horticulturists, botanical garden staff, or experienced plant enthusiasts. Many cities now have plant enthusiast communities where you can share photos and observed characteristics of plants, and community members usually enthusiastically help with identification. According to statistics, with guidance from professionals, plant identification accuracy can increase to over 90%.
Today, various plant identification apps have emerged, making plant identification 'one-click accessible.' Currently, mainstream plant identification apps on the market include PictureThis, iNaturalist, PlantNet, etc. These apps work by using your phone camera to photograph parts of the plant such as leaves and flowers, then using artificial intelligence algorithms to compare with plant information in databases, quickly providing identification results.
Usage Tips: To improve identification accuracy, ensure sufficient lighting when photographing, clearly presenting key parts of the plant (such as the front of leaves, full view of flowers) in the center of the frame, avoiding cluttered backgrounds. Also, try to photograph from multiple angles, such as simultaneously capturing leaves, flowers, and stems - the app will comprehensively identify characteristics from multiple parts, resulting in higher accuracy. Data shows that under good photography conditions, quality plant identification apps can achieve accuracy rates of over 85%.
Cautions: For some plants with similar morphology (such as different varieties of orchids, Rosaceae plants), apps may have identification errors, in which case traditional identification methods need to be combined for further confirmation.
In addition to apps, there are many online plant identification platforms, such as the Institute of Botany, Chinese Academy of Sciences' 'PlantWise' platform, Baidu Image Recognition's plant identification function, etc. These platforms typically support uploading plant photos for identification, and some platforms also provide additional functions such as plant classification queries and plant distribution maps, suitable for more in-depth plant research on computers.
During plant identification, many people make identification errors due to overlooking some details. Here are common pitfalls and precautions to be aware of:
Many people rashly conclude when identifying plants by only looking at flower color or leaf shape, which is very prone to error. For example, plants with red flowers could be roses, Chinese roses, or scarlet sage - their leaf and stem characteristics differ greatly and must be judged by combining multiple characteristics.
The same plant's morphological characteristics can differ at different growth stages. For example, some plants' leaf shapes in the seedling stage differ greatly from the mature stage - if identification is based only on seedling leaves, misidentification is likely. Therefore, when identifying, try to observe mature individuals of the plant or understand the morphological changes at different growth stages.
In nature, there are many plants with similar morphology that may belong to the same family or genus but differ greatly in uses, toxicity, etc. For example, toxic oleander and common Chinese rose have somewhat similar leaf shapes, but if oleander leaves or flowers are mistakenly ingested, it can cause serious harm to the human body. Therefore, when identifying these similar plants, be sure to carefully compare detailed characteristics and consult professionals when necessary.
When observing and identifying plants, pay attention to protecting the plant's growing environment. Don't randomly pick leaves, flowers, or dig up plants, especially for rare and endangered plants - strictly comply with relevant protection regulations.
A: First, check if photography conditions are good - ensure sufficient lighting, clear images, key plant parts (such as leaf front, full flower view) in the center of the frame, avoiding cluttered backgrounds. Second, try multi-angle photography, uploading photos of multiple parts of the plant such as leaves, flowers, and stems for identification. If multiple identification results are inconsistent, you can check the similar plant list provided by the app, combined with the previously mentioned core dimensions of plant identification (leaf, flower, fruit characteristics, etc.) for comparison and screening, or upload photos to plant enthusiast communities or consult professionals.
A: When encountering unknown plants in the wild, first maintain a safe distance and don't randomly touch, pick, or taste. You can use your phone to take clear photos of the plant from a distance, including leaves, flowers, stems, growing environment, etc., then use a plant identification app for preliminary identification to see if the app marks the plant as toxic. If the app cannot accurately identify or marks the plant as potentially toxic, don't approach further. After returning to a safe area, you can upload photos to professional plant science platforms or consult plant experts to confirm the plant's species and safety.
A: If a plant is in a state without flowers or fruits, you can focus on observing leaf, stem, and growing environment characteristics. First, record in detail the leaf shape, edges, veins, arrangement, stem texture, color, presence of thorns or hairs, and branching pattern. Second, observe the plant's growing environment, such as whether it grows in forests, by water, or in rock crevices, whether it prefers sun or shade. Then, use plant field guides or online platforms to search based on leaf and stem characteristics and growing environment. Additionally, some plants' bark, branch cross-sections, and other characteristics also have identification value - for example, pine tree bark is scaly and resin flows from cross-sections, which can be used as supplementary identification criteria.
A: When beginning to learn plant identification, it's recommended to start with common, distinctive plants around you, such as common flowers in daily life (like roses, Chinese roses, chrysanthemums, peonies), fruit trees (like apple, peach, orange trees), and street trees (like poplar, willow, plane tree, ginkgo tree). These plants are widely distributed with unique morphological characteristics, easy to observe and remember, and related identification materials are relatively abundant. After becoming familiar with identification methods for these common plants, gradually try identifying less common plants, progressively improving your plant identification ability.
