They have soft stems that generally die back to the ground each year after flowering.

它們的莖很柔軟，每年開花後一般都會枯死在地上。

Herbs are usually low-growing and have a shorter lifespan, typically living for just one growing season, annuals, or a few years, perennials.

草本植物通常生長緩慢，壽命較短，一年生植物通常只有一個生長季，多年生植物則只有幾年。

Examples include basil, mint, and cilantro. Shrubs, on the other hand, are woody plants that are larger and have multiple stems arising from the base.

例如羅勒、薄荷和香菜。 灌木則是較大的木本植物，從基部生出多根莖。

They don't die back each year, but instead grow taller and bushier over time.

它們每年都不會枯死，而是隨著時間的推移長得更高更茂盛。

Shrubs are usually perennial, meaning they live for many years.

灌木通常是多年生植物，這意味著它們可以存活很多年。

Common shrubs include rosemary, which can be both an herb and a shrub, lilac, and boxwood. So while herbs are soft and often smaller, shrubs are woody and typically larger, with a more permanent structure.

常見的灌木包括迷迭香（既可以是草本植物，也可以是灌木）、丁香和黃楊。 草本植物質地柔軟，通常較小，而灌木是木質的，通常較大，結構也更牢固。
