In the month of August, it is usually organized for 10 days from August 6th to 15th. The theme for this year is to show respect to all the martyrs and freedom fighters of our country.
This year the main attraction is the monument India Gate, beautifully made from more than 250,000 roses, a fitting tribute to the Indian soldiers. 
On display were around 260 varieties of Anthuriam, Orchids, Celosia and Dianthus among others.
Every day thousands people enjoy the beauty of these flowers on display. It is mostly crowded in the evening on the weekdays. Best time to be in this place is the early afternoon. I had been here on the weekend afternoon. Even though it was crowded I had enough space to take some snaps.
Very minimal entrance fee is charged for the show. No charges for camera.
