The gathering of herbs was something that both Ella, Maria, and Isa exceeded in over Clark. Isa was a merchant, therefore, she had learned to care for the products she would sell. Her family had spent hours giving her the knowledge she needed to be able to properly pick, store, and then sell high quality herbs.
While this was just because of the importance that came with a mercantile family, it was something that truly surprised Clark. He watched as Isa was able to carefully pluck the green trumpet flowers at the base of each bloom. This lets the flowers remain intact as a plant and grow new buds later.
