Learn Farsi: کدام باغ گیاه‌شناسی گیاهان عجیبی از جمله بامبو دارد؟ - Which botanical garden has strange plants, including the bamboo?

Literally, از جمله means "from the collection" or "from the total" (the word جمله can mean "sentence" but also "total" or "whole"). In Farsi, it is used just like "including" or "such as" in English to introduce a specific example from a broader category you just mentioned (here, singling out bamboo from the strange plants).

How is the word گیاه‌شناسی formed?

It translates to "the study of plants." It combines گیاه (plant) and شناسی (study/knowledge of). When linked to باغ (garden) with an ezafe, it creates باغ گیاه‌شناسی which is the standard Farsi term for a botanical garden.

Why does the indefinite marker ی attach to the adjective in گیاهان عجیبی instead of the noun?

In Farsi, when a noun is followed by an adjective, the indefinite marker ی (meaning "a" or "some") attaches to the very end of the noun phrase, not to the noun itself. That is why it goes on عجیبی instead of گیاهان.

Could I use گیاه‌ها instead of گیاهان for the plural of plant?

Yes, you can. While ها is the universal plural marker today, plants and trees historically took the animate plural suffix ان. Using گیاهان sounds slightly more formal or scientific, which fits perfectly when talking about a botanical garden.
