I have always been getting flowers from The Love Garden at 910 Pasay Road Makati.
They deliver roses when the order is a dozen or more, I think 1,000 ang local. Many colors available, plus delivery charge depending on location. 5,000 yata ang Ecuador, yung long stem na malalaki. (Sorry, been a long time since I sent these. Baka 6,000 or more na.)
I forgot their number. I have the calling card at home. It's probably in the directory. You can look for Nancy and tell her you were referred by Mr. Clifford Cada.
Pero syempre, pinaka-mura pa rin if you go to Dangwa around 2AM to 4AM pagbagsak ng fresh na locals.
