Bird Cherry (Padus), fam. Rosaceae.
There are two species - European Bird Cherry of Hackberry, and Black Cherry or Chokecherry.
1. European Bird Cherry (Padus avium, Prunus padus). Grows in the city and in the forest. Blooms in late April together with other fruit trees of the rose family. The fruits are edible but not abundant; they ripen in the end of June till July, still being very tart. All the parts of the plant, except the fruit flesh, contain cyanide precursors, and require caution. There is information that many insects and bacteria (including the pathogenic) cannot bear the smell of bird cherry, particularly flowering. However, at slightly higher doses, the same occurs with humans. So, don't bring bouquets, which include bird cherry flowers, into rooms, especially closed! Bird cherry leaves, dropped into a well, in ancient times were considered an agent to poison the water.
