It's a soggy saturday, too soggy to garden for my taste, so in lieu of that I'm reading gardening books.
One of them discussed the search to find hardy rose varieties, and had this tip: check out the yards of abandoned homes or old cemeteries for rose bushes. If they've survived the neglect, they're probably a variety that's hard to kill, so take a cutting to grow yourself.
Now it's just not good form to rob tombs where relatives are going to care, so the author had this to add: "Checking the date on the headstone is important not only because it reveals whether or not the rose is a real survivor but also because it will spare you embarrassing encounters".
Yes, important tip, don't get caught grave-robbing. Gardeners and ghouls, please take note.
