A Grassium Z in the anime

Ash obtained a Grassium Z from a Totem Lurantis after completing the Lush Jungle trial in Currying Favor and Flavor!. He and Rowlet first used it in Trials and Determinations! to perform Bloom Doom. In Beauty is Only Crystal Deep!, the Ultra Guardians used it, along with Ash's Normalium Z, Rockium Z, Solganium Z, and Steelium Z, and Lillie's Icium Z, as bait for a Pheromosa.

A full set of type-specific Z-Crystals, including the Grassium Z, appeared in A Grand Debut!, where Hapu allowed Ash to choose his grand trial prize from them.

Mallow obtained a Grassium Z from Tapu Koko in A Recipe for Success! as a reward for helping Oranguru operate its forest café.
