Hi Guys, Glad to be back among you after two months. I am in Delhi after spending two months away in remote North East of India. I wish to thank you for you attention and comments made on previous few pics. I may not have been able to revert your comments but I have been through each one of them and feel overwhelmed. Have a great weekend folks ! via 500px http://ift.tt/1qn16Tq

Break the rules by AndreasJones
I had a few questions on why the sunflowers are facing east. The phototropic ones only follow the sun for a period. When the sunflower is growing the stem & material is soft and pliable, the unbloomed bud is light and will follow the sun during this phase. However, when the sunflower blooms the sunflower slowly stops growing, instead putting the energy into the seed head. At this point the rest of the sunflower (stem, etc.) starts to solidify, and will eventually solidify facing in an eastwardly direction and the bloom will no longer follow the sun. So, the phototropic ones do follow the sun but only for a time and once bloomed will eventually "freeze" facing in an eastwardly direction.
