I go for primarily color, then fragrance, then rebloom, then shape of the flower. I don't like the single petaled roses, but I do have a couple (Austrian Copper & Escapade). I love Austrian Copper for it's color & the fact it's an early bloomer & sooooooooooo easy to take care of... I don't take care of mine at all. I love Escapade because it's sooo fragrant!! I don't care for pink, but Escapade is VERY fragrant & looks smashing sandwiched between 2 Sunny Delights. But color is my primary ticket. That's why I have so many in the blue family.
