Why do plants bloom in spring? For us? No. The fact is that gradually from the ovary of flowers fruits are formed with seeds inside.
And from the seeds next year, new plants will appear. Thus, plants need flowers to continue life.
Flowers at home
People keep some houseplants at home for beauty. In greenhouses, flowers are grown for sale. Some plants, such as oak and walnuts, have male and female flowers. But only a female flower can produce seeds and fruits.

Grape
Fruits of grapes form clusters. The grapes are small and not as bright as flowers. But inside each berry there are several seeds (seeds), each of which can give life to the next "generation" of grapes. Sometimes it happens that in certain plants the color of the flowers is so inconspicuous that they are often confused with leaves. These are, for example, linden and maple flowers.
Not all plants have bright flowers. Some of them are green or brown. For example, in herbaceous plants.
