Bingdi lotus
Bingdi lotus (), or Bingtou lotus (), is a species of lotus native to China that carries a pair of flowers on each flower stalk, whereas there is only a single flower on most other species of lotus. Bingdi lotus belongs to a special type named Qianban lotus () and is a treasure among flowers because it has all the essential parts of both the leaves and lotus. In Chinese tradition, Bingdi lotuses are considered both auspicious and joyous and as an embodiment of kindness and beauty. Growth
Generally speaking, a lotus forms only one flower bud, one meristem centre and blossoms into one flower. But if affected by some special outside surroundings or inside variations, the flower bud may be divided into two meristem centres and then grow into two buds like the twins. Afterwards, two flower stalks will appear on the same stalk, and then they both come into blossom and finally bear fruit-pod. Value
