棵 vs 株 (kē vs zhū): which plant classifier to use
棵 (kē) is the everyday classifier for trees and plants, used in most informal and formal contexts. 株 (zhū) is a more formal and horticultural classifier, often used for individual plants, seedlings, or in scientific writing. The main difference is register and specificity: 棵 is general, while 株 emphasizes the plant as a distinct entity.
棵 and 株 are both classifiers for plants, but they differ in register and nuance. 棵 is the default, everyday classifier for trees, bushes, flowers, and other plants, suitable for most contexts. 株 is more formal and specific, often used in horticulture, botany, and for emphasizing individual plants, especially seedlings or specimen plants. While they can sometimes be interchangeable, choosing 株 adds a formal or technical tone.
When to use each
Use 棵 as the general classifier for trees, shrubs, and green plants in both spoken and written Chinese. It is the standard choice for counting plants like 树 (tree), 草 (grass), 花 (flower), and most other plants in everyday language.
Use 株 for counting individual plants in formal, horticultural, or botanical contexts. It is common with 幼苗 (seedling), 植物 (plant) in scientific writing, and when emphasizing a plant as a separate specimen. It also appears in fixed expressions like 一株 (one plant).
In some contexts, 株 can replace 棵 for a more formal tone, but using 株 for a common tree in casual speech may sound overly technical.

- 株一株幼苗yī zhū yòumiáoa seedlingHorticultural or formal context; seedling is a typical object for 株.
- 棵这棵植物长得很好。Zhè kē zhíwù zhǎng de hěn hǎo.This plant is growing well.Common, neutral way to refer to a plant.
- 株这株植物是引进品种。Zhè zhū zhíwù shì yǐnjìn pǐnzhǒng.This plant is an introduced species.Formal or scientific tone; 株 emphasizes the plant as a distinct specimen.

Common mistakes
- Using 株 for a common tree in casual conversation (e.g., 一株树 sounds overly formal; use 棵).
- Using 棵 for a seedling in formal botanical writing where 株 is preferred (e.g., 一株幼苗 is standard).
- Assuming 棵 is only for large plants – it works for all green plants, including small flowers.
- Overcorrecting by always using 株 for plants; in daily speech, 棵 is the natural choice.
FAQ
- When do I use 棵 vs 株 for plants?
- Use 棵 for most plants in everyday situations (e.g., 一棵树, 一棵花). Use 株 in formal or horticultural contexts, especially for seedlings or when emphasizing the plant as an individual specimen (e.g., 一株幼苗). If you are unsure, 棵 is safer for general conversation.
- Can I use 棵 for a seedling?
- Yes, you can use 棵 for a seedling (e.g., 一棵幼苗), and it is understood. However, 株 is more precise and expected in horticultural or scientific settings.
- Is 株 only used for small plants?
- No, 株 can be used for plants of any size, but it often emphasizes the plant as an individual unit. It is common for seedlings and specimen plants, but not exclusively small ones.
- Which classifier is more common overall?
- 棵 is far more common in both spoken and written Chinese. 株 is limited to formal, technical, or horticultural contexts.
