Surprise birthday rose bush!

To add to all of yesterday's Birthday celebrations, last night my parents gave me this beautiful rose bush. I don't know the name of the rose....but it looks very healthy and there are about five beautiful flowers in bloom.
Each rose seems to begin by having pink petals, with a slight yellow tinge....and, as the flower develops, the middle part becomes all yellow, with a pink 'halo' of outer petals closest to the stem.

Derek has re-potted the bush into a much bigger container, and hopefully we'll watch it thrive and grow!
