Rhubarb new growth.

Brought some rhubarb back from mums garden and one of the stalks had a bulbous sack next to it and inside was this small new growth surrounded by sap. Very sticky. Have never known how they grew up so was very amazed. I have cooked it with ginger and without sugar and have not yet eaten it as I will share it with a friend and her sister. Hope I haven't stopped the further production of new shoots on the crown.
