A dense cluster of small, white flowers fills the frame, suggesting a flowering shrub or tree. The flowers are tightly packed together in bunches along thin, dark brown branches. A few green leaves are visible amidst the white blossoms. In the upper right and along the right edge of the frame, grey stone or concrete is partially obscured by the flowers. The setting is unidentified, and there is no indication of Sirius, Russia.
