Oxypetalum For Gifting: Don'ts

Basic Care Steps For Cut Oxypetalum


Pro-Tips for Oxypetalum Flower Care

  • The milky sap that oozes out from their stems can form a waterproof seal that stops the flower from absorbing water. To prevent this from happening, you may lightly burn the cut stem. Advisable to wear gloves when handling them.
  • Keep the flowers out of direct sunlight, and as cool as possible without freezing.



Tweedia, or Oxypetalum Coeruleum, is a group of flowering plants in the Apocynaceae family. Native to South America (namely Southern Brazil to Uruguay), these dreamy flowers were named after the Royal Botanic Gardens’ head gardener in the mid 19th century, James Tweedie. Don’t confuse the name for Tweedledee and Tweedledum from Alice in Wonderland! 😉


Oxypetalum is derived from the Greek words “oxys” which means sharp, and “petalum” meaning petal. Sometimes known as the blue star, it makes a statement in any flower bouquet while adding a delicate touch to it. Though adored by many for its soft blue colour, the Tweedia also comes in pink and white—both of which are an extremely rare find but in high demand!


If you’re looking to send a peace offering to someone or just want to show affection to a dear friend, perhaps a bunch of lovely Tweedia would do the trick. Grace someone’s household with these starry flowers and watch them smile from ear to ear. Or if you’re adventurous and bold enough, go hunt for a white or pink coloured Tweedia!
