My try: 1. Paeonia Lutea 2. English Laurel

Yes, perhaps Spiraea japonica, 'Goldflame' or similar.

Could be Pieris japonica. Look that up and compare pictures of leaves to what you have.

Hi, Christina. Well, the color change could be due to temperatures. Roses sometimes have a darker, more intense color in cooler temps, and less intense color in hot temps. Your rose may have pink or mauve undertones that come out in certain temps or when exposed to more or less sunlight. Or, it could be that the rose was grafted onto something else, the original rose died and this is the rose that was used as rootstock. But, let's put that idea on the back burner for the time being. :-) What else can you tell us about the rose? Does it only bloom once per year? Does it bloom several times per year? Is it almost constantly in bloom throughout the season? Does the rose have a fragrance? If yes, is the fragrance strong or light, does it have a spicy, fruity, or a purely rose smell? Or, does it have no fragrance at all? Looking at the pictures, it looks as though your rose has few prickles/thorns on the canes. Is that true? Or does it have lots of prickles/thorns? How big does the plant get? How big did it get at your parents' house? A picture of an open bloom would help if you can get one. Those leaves are quite distinctive; someone may be able to suggest an ID based on them. Hope you can answer some of the above questions, and I hope you find an ID for your pretty rose.
