Here's a picture of a mystery rose in the garden. It's fairly upright. It has more thorns than any other rose I've seen.
Stems tend to be red.
There isn't much written about China roses until they were brought to Europe in the 17th Century. China roses were a hit because they bloomed more often than once a year. Blooms tend to be semi-double. Bushes tend to be reddish. I've ever seen.
