Chase painted Seaside Flowers in Shinnecock, Long Island, where he taught art during the summer from 1892 to 1902. Chase encouraged his students to find beauty in landscapes that at first glance seem unremarkable, which he has done here. By breaking up the swath of scrubby bushes and grass with a diagonal slice of sea on the left and dirt path on the right, the artist enlivened a section of typical Long Island shoreline.
The figures include Chase’s wife, four of his daughters, whom he often painted, and an unknown boy, so the painting can be understood as a happy memento of summer vacation. However, the artist also used the people as compositional elements to add visual interest. He distributed them across the canvas in groups of one, two, and three, and their white clothes and verticality contrast with the green and blue horizontal bands of earth and sky.
