Alida Withoos was - with her brother Pieter Withoos - one of the many artists from Hoorn who painted plants while in residence at Vijverhof. Agnes Block's stepson owned a summer house in Purmerend, near Hoorn. Other painters from Hoorn were Johannes Bronkhorst, Herman Henstenburgh, and a friend of Alida's father, Otto Marseus van Schrieck.
