Blue finch likes a cool and humid climate, and is more resistant to cold than heat. It grows particularly well in humid places and is not resistant to drought. There are two kinds of propagation methods: seeds and nutrition, with strong vigor and competitiveness. It often grows in patches, forming clusters dominated by blue broom. Bluebird is resistant to trampling and has strong regeneration ability, but the seed setting rate is low, and the pods are easy to crack when they are mature. It is difficult to harvest seeds in the wild state.
