Cryptanthus bivittatus, a fascinating star-shaped bromeliad

Cryptanthus bivittatus (Earth Star, Starfish Plant)

Our 3 year-old potted Cryptanthus bivittatus 'Ruby' (Starfish Plant or Earth Star), shot February 2009This attractive cultivar ‘Ruby’ of the species C. bivittatus as pictured on the right, were just tiny tots in a 3-inch plastic pot when they joined our garden family in early 2006.

Their unique star-like shape that resembles a starfish and the fabulous stripy colors of their variegated foliage fascinated and captivated us so that morning 3 years ago and still does! Looking so adoringly cute and pretty as they waited to be adopted, it was an instant attraction both ways as our hearts warm towards this impressive pair. Cost us almost nothing for these jewels, just RM3.00 and dirt cheap!

To date, they have never flowered but had rewarded us with 2 pups since. Hooray, we now have 4 plants! :D

You’re sure to fall in love with this stunning beauty that grows easily and is relatively fuss-free.

Plant Profile, Culture and Propagation :

  • Botanical Name: Cryptanthus bivittatus
  • Common Name: Earth Star, Starfish Plant
  • Family name: Bromeliaceae
  • Etymology: The genus name, Cryptanthus, is derived from the Latin word, ‘krypte’, meaning ‘hidden’ and the Greek word ‘anthos’, meaning ‘flowers’.
  • Origin: Native to Brazil
  • Plant type: Cryptanthus bivittatus 'Ruby' (Starfish Plant or Earth Star) in our garden, November 2006Ornamental bromeliad that is popularly grown for its striking foliage.
  • Features: Cryptanthus bivittatus is one of the most popularly grown species of the genus Cryptanthus that has over 50 species and more than 400 cultivars and hybrids as listed by the Florida Council of Bromeliad Societies. C. bivittatus is a terrestrial bromeliad that is low-spreading and slow-growing, reaching 6 inches (15 cm) in height. A smaller and petite species of the genus Cryptanthus with beautiful variegated leaves that are spirally-arranged in a flattish rosette that ranges from 6-12 inches (15-30cm) in diameter.
    Cryptanthus bivittatus 'Ruby' (foliage color changes with lighting conditions), February 2009 in our gardenThe rosette formed by the colorful slender leaves with pointed tips, takes on a star-like shape that resembles a fallen star or starfish, hence attributing to its common names, Earth Star and Starfish Plant.
    An evergreen perennial that bears stiff and strong leaves which are elongated and lanceolate in shape, with undulated and serrated margins and bending backwards at the tips.The leaves measure between 2-6 inches (5-15 cm) long.
    Flowering Cryptanthus 'Le Rey' (Earth Star, Starfish Plant) with pupsThey are attractively variegated with longitudinal stripes in a combination of 2 or more colors, ranging from various tones of pink, red to crimson or maroon, white to cream and light green to dark olive-green.
    That too, color changes according to the intensity of light the plant receives during growth, vibrant in strong light and dull in shade or low light. Leaves undersides are colored light ash-grey.
    Cryptanthus bivittatus var. bivittatus (Earth Star, Starfish Plant) with flower buds and pupsA mature plant will produce a cluster of tiny 3-petaled flowers in white, which is nestled in the center of the rosette. Simply beautiful and showy against the coloured foliage.
    It will also produce offsets or pups (baby plants) readily from the leaf axils or from the base of the of the parent plant, to continue its generation and increase your collection.
  • Culture (Care): Cryptanthus bivittatus grows easily with minimum care. Given the right conditions, it will reward you handsomely with its stunning variegated foliage in fabulous colors.
    Light: Bright light indoors or full sun outdoors for best foliage color. However, extreme sunlight that causes bleaching or sunburn should be avoided and a filtered sunny location is much preferred. It tolerates low to medium light or shade, but colors will be less vibrant, dull or change altogether.
    Moisture: Medium water requirement and moderately drought tolerant. It loves humid conditions.
    Soil: Any kind of loose and porous potting medium, such as soil mixture of peat, sand and perlite that can hold moisture yet well-drained. Keep soil evenly moist but not soggy and never allow to totally dry out.
    Others: Cryptanthus bivittatus 'Pink Starlite' (Starfish Plant or Earth Star)Foliage colors change according to the amount of light received. So, if their colors fade, relocate to a sunny or brightly lit site and move to a shadier spot with diffused light if foliage gets bleached. Grow them in plastic pots to better conserve moisture. Try not to overcrowd Starfish Plants in small pots that will either hinder the proper development of the root system which is their vital source of water supply or may prevent water from reaching the soil by its spreading foliage forming a tent above. It loves a humid condition which can be increased indoors by standing the pot on a tray of pebbles half-filled with water. Feed once fortnightly with a diluted strength of a balanced liquid fertilizer. Earth Stars are relatively free from pests or diseases, and very rarely bothered by scales and mealy bugs.
    For temperate regions: Hardiness: USDA Zone 10-11. More info at Dave’s Garden with flower photos. Best to grow them in containers that can be overwintered inside if necessary. Feed with a liquid fertilizer for flowering houseplants at every third watering from spring to fall.
  • Propagation: From offsets or pups that appear from the leaf axils or at the base of the parent plant. To propagate new plants, remove the pups from the mother plant with a slight tug when they are at least one-third the size of the mother plant. Then insert the pup’s bottom stem tip into potting soil and firm the soil around it. It should root easily in moist soil and warm conditions.
  • Usage: Cryptanthus bivittatus 'Ruby' in the foreground, taken Sept 2006C. bivittatus will be excellent for container gardening, terrariums or grown direct on ground. Being an easy-care plant that is very attractive and tolerant of indoor lightings, it is ideal as a houseplant or ornamental plant for interiorscape in offices, commercial complex and others. Suitable too for greenhouses and conservatories, or use as an accent on window sills, patio tables and decks. Ideal for outdoors too in mixed planters, and as groundcovers in garden beds and borders with other low-growing plants for color contrast.

Some of the named cultivars of C. bivittatus are:

  • ‘Ruby’ (synonym: C. bivittatus var. atropurpereus) – 5 stripes: stripes at the edges and center are colored dark maroon (fading to green in poor light or dark olive green in high light), with the 2 stripes on either side of the central stripe in rich ruby red to rose pink (changes to cream or creamy green in low light);
  • ‘Ruby Star’ – nearly identical to ‘Ruby’ but without dark edgings;
  • ‘Pink Starlite – 3 large stripes but sometimes has thin bands centrally: stripes at the edges are candy pink and the central stripe is olive green or paler;
  • ‘Starlite’ – a sport of ‘Pink Starlite’ that is nearly identical to it but has 2 additional olive green stripe at the edges;

Cyptanthus ‘Le Rey’, a cultivar of acaulis ‘Roseus’ is another exceptional beauty that fascinates us. Truly captivating with a broad central stripe in yellowish-green that sometimes has thin striations and bordered by baby-pink edgings. View its lovely features at the FCBS link provided below.

    Hi there.I am wondering where did u buy those lovely Crypthantus of yours.I have Crypthantus zonatus and brown Crypthantus bivittatus but not not those vibrant coloured ones.I have hunted everywhere in Penang nursery!!

  11. Jacqueline Says:

    We got them from a garden nursery nearby in KL., Rianna. Sometimes we’ve seen them on sale at hypermarkets, like Tesco Extra or Giant.
    All the best in your search.

  12. Cassandra Says:

    I am so glad I came across your website! I have been growing Cryptanthus plants for YEARS and never knew what they were called. I picked one up at Home Depot in a small town in North Carolina, and quickly learned that they liked a lot of light in order to get that gorgeous pink color. I have more pups than I know what to do with, so I have made them my “official” house plant (along with a large aloe vera plant that the cat can’t knock over, they are the only plants I have in the house). I have an offer for you–I got some GORGEOUS photos of one of the largest plants blooming! It has buds that have yet to flower, as well as the tiny, delicate white flowers. I have to transfer the photos from my camera to my computer, but if you send me your email address, I’d be happy to share when I get around to switching photos between machines (the quality is quite good, too). I am sure you can find photos of blooms on the Internet, but in case you can’t and would like some good ones, please let me know.

    I raise a few worms for composting and fertilizing, and I would encourage you to do the same, as worm castings (AKA worm poop) is full of nitrogen, and we know how plants love nitrogen–it’s the world’s best fertilizer! You may be able to find some packaged castings at a gardening supply store or a “big box” hardware store that has a gardening section. The best way to get the goodness of the castings into the plant is by making “worm tea”. I use plain old coffee filters, put about a tablespoon full of castings into the filter with a long string tied around the top, and then let it steep in a gallon of rainwater for an hour or two. My pups and mama plants LOVE this form of fertilizer. It’s 100% non-toxic (use unbleached coffee filters), and it won’t hurt any other plant (or critters living in them) that you wish to water, either. Siimply putting the castings in the dirt often will bring unwanted worms (they can live quite a while in their coccoons) or funky plants whose seeds either made it through the worm’s gut or somehow found its way into the bin where the worms lived, although they are easy to pluck out so your Cryptanthus can grow in peace. I also keep a humidifier going 24/7 for the plants and for me.

    Thank you again for giving a name to the treasure I picked up at a hardware store! I have so many pups, I may start my holiday presents NOW (March) by putting pups into small containers so they will be a hefty size after a long North Carolina spring, summer, and fall (and the larger plants which produce offspring are showing no sign of slowing down, either). I think it’s the worm tea, but who knows. . .

  13. Jacqueline Says:

    Great to know that you’ve finally ID’ed your treasured plant with help from this site, Cassandra… we’re happy for you!
    Wow… flowers, buds and so many pups on your plants! Hmm… I’m green with envy ‘cos our plants have never bloomed for us. :(

    Yes, we’d love to have a blooming Cryptanthus photo to add to our article above. I’ll email you shortly with details. Thanks so much for the offer, Cassandra.

    Thanks too for sharing about using worm castings as a fertilizer. This is something new to us and others too may find your experiences helpful.

  14. Cassandra Says:

    A note about the worm castings: not all worms are created equally. Just as there are different species of cats and dogs, it’s the same for worms. The worms that do best are the ones used for composting. I have found that the hardiest and hardest working worms are from Uncle Jim’s Worm Farm (www.unclejimswormfarm.com), and they are the SUPER RED WORMS (as opposed to the regular red worms–different species). If you check out his blog under the Education tab, there is a fantastic article about brewing worm tea. It’s more of a medium- to large-scale operation, but worth reading, and it can be scaled down to a smaller project.

    Also, I may have extremely healthy plants (not just my cryptanthus family) because I always give them water that is free of chlorine. If it’s tap water, then I let it sit for a day or two in a used milk jug with a big hole cut in the side opposite the handle (the water can go in and out of the jug using the same opening, plus you’re recycling some plastic that would otherwise end up in a landfill). Even better is water collected from a rain barrel, as the pH is different, around 5.5; rain water and distilled water do NOT have the same pH! Plants are designed to drink water from the sky, so why not give it to them? Be careful not to let any water stand around unprotected by wire mesh, as mature mosquitoes will lay their eggs in it.

    Hi again, Cassandra!
    Thanks for sharing your gardening experiences… definitely helpful and very appreciated.
    Btw, we can’t thank you enough for sharing the lovely shots of your blooming Cryptanthus ‘Le Rey’ and pups… just perfect to complement our article. Thank you very much and God bless!

    Hi Jacqueline,
    I just came across your website to find some care information on my Crytanthsus that has taken on a life of it’s own. I was reading posts from Cassandra and thought I could do the same for you in terms of pictures, as mine is in the “process of blooming”, which looks like a small pineapple in the center, then I noticed small tubulars, possibility small flowers or offsets, under each top leaf, under the bloom center. There are 5 of the tubular sprouts. I’ve had and grown many, many genus of Bromeliads, however, randomly picked up this inexpensive plant not expecting much,other than the pop of color the Pink Star illuminates.

    Of all the plants in my extended collection,this one was the one I didn’t expect much from. I’m extremely surprised by the bloom and whatever lies beneath those leaves!

    My secret,I would have to eagerly tell you, is a family owned nursery that sells every type of plant and everything you need to be successful in growing and blooming indoor and outdoor beauties. They carry a fertilizer made by a company called Fertilome. They have a Bloom and Rooting Fertilizer that has brought stagnant Hoya back from their inability to grow etc. Fertilome is GOLD for all plants!

    If it’s okay with you,I would like to email you pictures of my Crypthansus as it’s in the blooming stage,along with showing you the tubulars it’s producing. I truly do not know what they’ll be,but it certainly was a nice surprise to see them.

    I wish you well with your Crytanthsus through this upcoming season!

  17. Jacqueline Says:

    Yes, Roxanne… we’d love to take up your offer of pictures of your about-to-bloom Cryptanthus and pups. I’ll email you shortly with details. Thanks so much for the offer.

    Thanks too for sharing your gardening observations with this plant and introducing Fertilome.

Welcome! You are valuable to us and we love to hear from you. Leave us a comment or share your experiences. Also, please inform us if you find a broken link in any of our articles. Thank you.
