Chives Tasting Like Grass: Grass Invasion or Variety Confusion?

Established chives developed flat, narrow, flavorless leaves but still bloom purple. The gardener confirms it's not grass takeover.

Possibilities

• Garlic chives have flat leaves and garlic flavor—could it be a mix-up?
• Hot weather diminishes chive flavor. Taste early morning for true flavor.

If neither applies, Elyse recommends digging out and restarting—sometimes plants just lose vigor inexplicably.
