Red-Tinged Sedum

Six weeks since these three leaf cuttings of Sedum rubrotinctum have pushed out roots, they now each have a cluster of tiny leaves with visible reddish tinge. I’m really pleased that they’re doing well.

Today, I learned from various sources five things about Sedum rubrotinctum that I didn’t know before:

  • First, the plant is poisonous and the sap from its cuttings is a skin irritant.
  • Second, this succulent produces bright yellow, star-shaped flowers in springtime—but not always! Flowers are produced only when the conditions for its flowering have been satisfied.
  • Third, its reddish hue becomes more pronounced the more it is exposed to the sun. Its colour-change is a kind of adaptive mechanism, a stress response.
  • Fourth, its botanical name is also written as Sedum x rubrotinctum because it is a hybrid of Sedum pachyphyllum (that other sedum I have on my windowsill) and Sedum stahlii.
  • And lastly, aside from being called a jelly bean plant, Sedum rubrotinctum‘s other common names are “pork and beans,” and “Christmas cheer.”

Sedum rubrotinctum. I love the specific epithet (the second part of a plant’s botanical name) of this plant, rubrotinctum. Without any knowledge of Latin and without consulting any book on plant naming, rubrotinctum just sounds like something dipped in red ink. Sedum rubrotinctum, the sedum tinged with red. I can’t wait for these plantlets to grow bigger and exhibit more of its reddish hue.
