Question

select all the adjectives the tiny sapling may look delicate but it will grow into a large tree in several years

Answer 1

Adjectives (main): tiny, delicate, large.

Note: "several" is a quantifier/determiner modifying "years" and is sometimes classed as an adjective-like word, but traditionally it's treated as a determiner rather than a descriptive adjective. "the" and "a" are articles (determiners), not adjectives.
