Instead of roses, how about impatiens, also called jewelweed? These pics were taken the other day from my sun-room.
Jewelweed contains 2-methoxy-1-(4-naphtho)quinine, an anti-inflammatory and fungicide that is an active ingredient in some formulations of Preparation H!
In ancient China, Impatiens petals mashed with rose and orchid petals and alum were used as nail polish: after leaving the mixture on the nails for some hours, it will color them a pink to reddish hue. [Source: Wikipedia]
