Xanthoceras is a genus name that means “yellow horn”, which is why it’s most commonly called Yellowhorn. This is also known as Goldenhorn, Shiny Leafy Yellowhorn and Chinese Flowering Chestnut.

The genus name of this plant is derived from the Greek words “xanthos” (yellow) and “keras” (horn, which refers to the hornlike features between petals).

It naturally grows as an erect, herbaceous or woody shrub, which can be classified as annual or perennial depending on the species. The large, pretty tubular flowers make this popular.

Multiple heads are produced in a single stem. Each flower head has papery bracts that curl over and enclose the disc florets.

Colors range from yellow to orange, white to purple, while some are binary colored, but the bracts and disc florets don’t share the same shade. The long, sturdy stems are an obvious reason why it is good for ornamental use.

“Xeros” is a Greek word that means dry, and “chrysos” translates to gold, which refers to the dry golden bracts of the flower. As for its English name, it is given based on the fact that the bracts have straw-like texture.
