Blueberries are blue fruits.

Blueberry fruit size and color vary depending on the species. The fruits of most varieties are dark blue or violet when ripe, such as rabbiteye blueberries, highbush blueberries and lowbush blueberries, while a few varieties are red. Fruits are spherical, oval, oblate or pear-shaped.

The flowering period of blueberries is obviously different due to climate and varieties. It blooms in early to mid-March in southern my country and from April to May in the north. The flowering period is generally 15 to 20 days, and the longest is 40 days. The flowers are borne on an elongated axis and form a raceme. When the flowers bloom, the vegetative buds begin to develop into vegetative branches. The vegetative branches stop growing when they reach a certain level (different lengths), and the last thin-pointed young leaf at the top turns black into a black tip

1. Selection of blueberries

1. Look at the surface

There is a layer of white mist on the surface of blueberries. This layer of white mist is said to be found only in blueberries without pollution. So don’t worry about the layer above, just choose.

2. Look at the color

Dark purple is better, light color only shows that it is immature. So choose dark-colored blueberries, which are more mature and will be sweeter and more nutritious.

3. Look at the size

The big ones are artificially bred, while the small ones may be wild. But there are very few wild blueberries now. Everyone goes to pick wild blueberries. I believe that the wild ones have been harvested long ago. But to be honest, larger blueberries taste much better than smaller ones, and their nutritional value is the same.

4. Look at the skin

Blueberries will have small depressions after being left for a long time, which are small pits of rot. One time, the little chicken picked out two boxes of blueberries. One box was good, but the other one went home and saw some small holes that you couldn't see unless you looked carefully, so he was fooled. .

5. Look directly at the production date

In order to ensure freshness, boxed blueberries usually have a production date. Simply check the production date directly. The earlier the purchase date, the better.
