Tillandsia neglecta is a compact and hardy air plant known for its thick, stiff leaves that form a dense, upright rosette. The leaves are typically dark green, sometimes with a bluish or silver tint, giving the plant a robust, almost succulent-like appearance. When in bloom, T. neglecta produces striking tubular flowers, often in shades of vibrant blue or purple.

This species thrives in bright, indirect light and requires regular misting or soaking to maintain its health.
