Calathea lancifolia – Rattlesnake Plant

Calathea lancifolia – Rattlesnake Plant

Now botanically known as Goeppertia insignis, this lovely foliage perennial brings striking pattern and texture to an indoor plant collection. Its long, slender, wavy-edged leaves are pale green with bold dark markings and rich purple undersides, creating an attractive display even without flowers. Give it a warm, humid position with bright, indirect light and protection from cold drafts.

Its clumping habit makes it an excellent container plant for a bright room.
