Women and flowers have a love-love relationship since ages. Emperors used to order development of flower gardens just for their queens. Flowers are the eternal symbols of love. On your first date, take a bunch of flowers for your date. These need not be too expensive. Don’t take red Roses. Take yellow Roses instead if you wish to take Roses. You can take lots of other flower varieties like Tulips, Lilies, Asters, etc. Pick up a fresh, good looking bunch and present it to her.
On your second/third date, when you think you are serious about her, woo her with Orchids - which are considerably expensive. Women always love flowers. So you will be in her good books!!
