Hi,
Yellow roses are my favorite too, and I recently fell in love with Henry Fonda and Oregold. I also have Gold Medal and White Licorice.
HF is a deep yellow, nice buds and wonderful fragrance. Oregold blooms beautifully and is easy to care for. White Licorice has a licorice-lemon scent to it. It's supposed to be pastel yellow-white, but mine are butter yellow, like margarine. *shoulder shrug* A lot of people have good things to say about Gold Medal, but I can't say the same. It's been very temperamental with me so far.
Good luck with your choice.
