Like a mystery?

Old Garden Roses are full of them. Mostly based off  history and speculation. Granted Modern Roses date back to 1867. However Old Garden Roses' classes are older than that. And it was the old garden roses that plant explorers were paid to collect from China and other countries.
Having read lots of descriptions of roses dating earlier than 1867, a lot of roses fit in one description. Also there were multiple roses given the same name. And the same rose was often given multiple names.
Another factor in the history and speculation is names of roses were sometimes changed when the roses were introduced into other countries.
A couple of roses that could be speculated about are Bon Silene and Mme. Berkeley.
First the easier of the two, Mme Berkeley. Older descriptions of this rose states that it bears hips. Apparently in the 1970s a person found a rose that they believed to be Mme. Berkeley. Old roses faded out of popularity and many were lost. The rose was introduced back into the market as Mme. Berkeley. But alas, it doesn't have hips, so it is not the same as the original. Where did the original go, and who took it's place.
Now onto Bon Silene. Past descriptions for it describe it "seeding freely." Yet when I asked breeders now, they said that they don't get seeds. What happened? There is a recent rose that came from Bon Silene as the seed parent. Are there more than one rose that goes by the name of Bon Silene?

Bon Silene or something else?

So, if you like mysteries, history, and speculation, Old Garden Roses are the way to go.
