花梗

1. Origins, structure, and basic meaning

• Structure: 花梗 is read as かこう and is a botanical noun for the stalk supporting and connecting a flower or flower cluster to the stem.
• Basic usage: Use it when locating the stalk relative to leaves or in 花梗の先に花が咲く for a flower at its end.

2. Common pitfalls and similar expressions

• Contrast with 茎
  • 茎 is the plant stem broadly, while 花梗 singles out the stalk supporting a flower or inflorescence.
• No fixed size
  • The example stalk is slender, but the word itself does not require one particular thickness or length.
