September visit to Lalbagh - Hydrangeas

I went to Lalbagh one morning in search of pots and seeds. The picture taking started even before i reached, with the lantanas on the way.

I headed to the nursery and examined the seeds and then the potted plants for sale. There were several lovely hydrangeas. Now the color of hydrangeas depends on the pH of the soil... the blueish ones have more Aluminium in the soil. Isn't that fascinating?!
