✕Common Mistakes
Es de plantas.
‘Es’ is singular; the subject is plural, so you need ‘son’.
Son de planta.
The noun must agree in number with the implied subject; use the plural ‘plantas’.
Está de plantas.
‘Estar’ is not used for inherent material; use ‘ser’ or ‘estar hecho de’.

Cultural Tip
In Spanish, ‘ser de’ is used for the intrinsic material of an object (e.g., ‘La mesa es de madera’). ‘Estar hecho de’ is also correct but adds a slight nuance of the object being in a particular state. Both are common, but ‘son de plantas’ sounds more natural when speaking about a group of items.
