Hi Rose Lover,
I have recently joined this site looking for information. I went to the forum and noticed your question. It just so happens that I like yellow roses too. Although
I am a newbie to roses, I have always loved them. I started buying my roses from a site called "Jackson & Perkins". I bought a floribunda called " Sunny Days". ( I just bought it one month ago. It has just started to sprout buds.) I also went to another site called "Heirloom Roses". You may want to look at the variety for roses, especially the "English Legend" roses. There is another site called "David Austin Roses". They have lots of roses to chose from there as well.
The only site I bought from is Jackson & Perkins. Now that I know more sites I will buy from Heirloom, they are very reasonable, and have a wealth of information about growing roses!
I was surprised no one else bothered to respond to your question.
Good luck in your pursuit!
