Well, the plants are few and far between, but the ones I do have are profuse and beautiful! I'm in a similar situation - our 1905 home was in the same family from the 1920s until 2004. I was fortunate enough to talk to a man that grew up in the house, and he told me that his grandmother was the gardener in the family. She died in 1943, so my roses and irises are at least that old! He said that as a kid he hated mowing around the roses and tried his darnedest to kill them, so I know they're hardy and carefree! The only other things that I've been able to identify are grape hyacinths and pachysandra, both of which are a little invasive around here and weren't necessarily planted on purpose. I actually just took some pictures today. I think the white roses are sombreuil climbing roses (though they don't have anything to climb on), but I don't know what the pinks are.

Irises:

I believe the iris are 'Indian Chief'. I have some from my great grandmother that were passed on to me. :) I believe they are from Ayers - 1929.
