This series of oil paintings depict the secret forest's life. Mosses and lichens are organisms growing underneath our feet but are often unnoticed and overlooked, despite overgrowing old dead trees, boughs, and remnants of fauna and flora. If you come closer they appear to be a world of amazing shapes and colours – Kalinowska uses their organic forms as the subject of her paintings. Her paintings are based on the plants found in her motherland, but over time they have changed slightly. At the beginning of the series, she uses earth colours but in the latest works, colours seem more unreal, as if from a dream.
