Constance Kilgore's early abstract paintings were informed by the English terrain, particularly by prehistoric earthworks and stone circles found throughout Britain. Kilgore considered these monuments and their markings to be a form of communication predating written language, whose messages have since been muddied or lost.

This notion of lost communication resonated with Kilgore. An intuitive painter, she began stitching symbols, folds and pleats into her canvases - markings to evoke the landscape of the subconscious. In time, the markings began to suggest umbels, pods and other plant forms. Her Hortus Imaginarius cycle was born from these images.

A move to the countryside in the early 1990s prompted Kilgore's artwork to turn skyward. Her monumental cloud paintings combine the magnificence of nature and plein air painting with the spontaneity of abstraction.
