Cryptanthus warasii is a rare terrestrial bromeliad that grows into a large, spiraling rosette of thin, sharply, recurved, silver leaves with sawtooth edges. Small white flowers emerge in summer from the center of the rosette.

How to Grow and Care

These plants are widely available at nurseries and garden centers. They need a medium to bright light as indoor specimens.

Bromeliad care is easy and requires no special tools or fertilizers. Feed the plants with a half-strength fertilizer every month in the growing season.

Water needs are easily achieved by filling the cup at the base of the leaves. The water that collects in the pot should be emptied weekly to remove debris, and the dead insects the stagnant water tends to lure into the cup.

Set the pot in a saucer of gravel filled partially with water to increase humidity and help provide a moist atmosphere. Make sure the roots are not submerged in the water, or this might invite rot.

Some Bromeliads grow well as Air Plants, which are glued or nested onto logs, moss, or other non-soil organic items. These plants collect all the food and moisture they need with their leaves but need a little help from you in the indoor setting.
