I don't plan to buy any, but the first three could change my mind. I love red roses with a contrasting reverse, so Cherries & Champagne is a rose I know I would like.
Cosmic Clouds' purple cup-shaped blooms with the silvery reverse remind me of Cardinal de Richelieu and could be an improvement over it in my garden. The Cardinal is a Gallica rose, so it needs more frost than my zone provides in winter to produce plentiful blooms. Besides, Cardinal de Richelieu is a once-bloomer and Cosmic Clouds is a reblooming shrub.
Desert Sky is intriguing because Regan says it's a combination of mauve and orange. That sounds like a russet rose and I'm crazy about russet roses.
