Growing Cryptanthus Bivittatus
The plants can have ten to twenty leaves, each with tiny teeth or thorns on their wavy margins. The leaves taper to a point at the end which gives the plant its pretty star shape.
The plants can be striped in both ivory tones and various shades of red and pink. The plant will grow to about 6″ tall and 15″ wide.
It is a moderately slow grower.
Cryptanthus Bivittatus does best in a well draining soil, amended with lots of organic matter. It prefers a slightly sandy soil.
Place Red Star Bromeliad in a slightly shady spot. Too much sunlight and heat can make the leaves wither and shrivel up.
Some morning and late afternoon sun with protection from midday sun is ideal.
If the plant has too much shade, the color of the leaves will be diminished.
Small white flowers appear in the center of the rosettes of leaves. The flowers of the plant are somewhat insignificant.
This bromeliad is grown more for its leaves than the flowers.
Many bromeliads will re-bloom after flowering, but the earth star acts differently. The mother plant will slowly die back after flowering, while sending out pups at the same time.
Watering Needs of the Earth Star:
Cryptanthus Bivittatus is drought tolerant once it is established. Unlike other bromeliads that have a “cup” that holds water, red star bromeliad does not have this feature, and must be watered from the root area.
Water lightly when the soil is dry to the touch. In very hot climates, the plants does best with regular watering.
Fortunately, the plant will send out small plants, called pups, that form at the base of the plant.
These will replace the original plant when it degrades after flowering. Just pull the pups off and plant them up.
The plant is also propagated by division, making sure that each plant has a bit of the roots. Red star bromeliads will grow from seed, as well.
Germinate the seeds on a damp paper towel.
Red Star bromeliad is a tender perennial does best in the warmer zones – 10 to 11, and needs to be protected from frost, or the leaves will become scarred and unsightly.
Earth stars like temps in the 55-65 º F range at night with daytime temps rising to the 70-90 degrees range. They can take a temperature as low as 34 degrees, but will not withstand a freezing.

What if the leaves of the plant have turned from red to almost pinkish green? Is it (red star) dying? What should I do?

My pink Cryptanthus was originally very pink when I purchased her. Then after the summer, I had to take her inside as I live in Canada ! 🥶 and that’s when I noticed the leaves had almost lost all their pink. There was very little light shades of pink here and there, but nothing more. I moved it to a macrame plant hanger, in front of my window (sun comes up there, so at noon-ish it’s over the house, so not too much direct sun. And within a week, the pink came back ! And as of today, all the leaves are a dark dark pink and it flowered and grew three pups, two of which I’m getting ready to remove from the mama. Give it a lot more sunlight ! The pink is gonna return and will be ever brighter and darker and just wow 🙂

Many plants with deep colored margins to the leaves get that way from being in just the right light conditions. It's possible that your plant may need a little more light to bring out the color.
