Calathea insignis is an evergreen perennial that forms clumps of narrow, erect, wavy-edged, lance-shaped leaves that are pale green with dark blotches and purplish red on the undersides that are soft to the touch.
White flowers that are small and tubular in shape are sometimes produced at ground level in spring.
It is a popular tropical landscape plant grown generally for its very showy foliage though it is very popular as a houseplant across the US, UK and Australia.
Its clumping form means that if grown indoors it may need re-potting form time to time, though they are easy to divide to create multiple potted plants.
