Common Names Earth Star, Dwarf Rose-Stripe Star, Starfish Plant
 
Zones 10A–12
 
A compact terrestrial bromeliad native to Brazil, Cryptanthus bivittatus is prized for its low, star-shaped rosette and vivid foliage. Leaf colors range from green and ivory to pink, red, and deep burgundy, often with striking central striping. Though its white flowers are small and short-lived, the plant’s sculptural form and color variation make it a standout in terrariums, dish gardens, and shaded tropical beds.
