  • Flowers: Narrow, tubular purple or violet flowers emerging from the center of the brightly colored rosette;
  • Roots: Minimal, wiry roots that serve only as holdfasts to anchor the plant to branches or rocks, not for nutrient absorption;

Care Guide

Watering

Soak once a week for 20-30 minutes, shake off excess water vigorously, and let dry upside down.

Fertilization

Mist with a bromeliad or orchid fertilizer diluted to 1/4 strength once a month.. Apply fertilizer only after the plant has been watered to avoid burning the delicate trichomes.

Aquarium Water:Use water from routine freshwater aquarium changes to soak or mist the plant; ensure the water is fresh and free of heavy salts or fish medications.
Pruning
  • Gently peel away dry, brown basal leaves from the bottom of the rosette;
  • Snip off spent flower spikes close to the base using sterilized scissors;
  • Trim dry or damaged leaf tips at an angle to mimic the natural leaf shape;
  • Leave pups attached until they are at least one-third the size of the mother plant before separating.
