I don't know but I have attempted to attach a link to help others ID the rose. It is very pretty. Is it fragrant?

Here is a link that might be useful:

It has a very faint smell. The smell is one normally associated with roses.

How big is this rose bush, is it relatively thorny?
Kinda looks like Iceberg at certain times of the year in certain temps it can have a cool pale yellow or gold at the center. Others a pure white, others spotted pink. Iceberg is a white or near white blend floribunda.

Check roses at HMF for some comparison.

It's about 3 to 4 feet, has a "normal" amount of thorns, grows in a "bush" fashion, blooms all season but blooms the most in spring and fall, has a very, very slight red tint to the outer leaves at times and is very lightly scented.

It might be 'Fabulous' or 'Moondance', both pretty recent offspring of 'Iceberg'.
