Tell me everything you know about roses please. :)
Did you have any successes and failures? Anything you wish you knew before you started? Any varieties you prefer over others (I'm in zone 5, if it matters).
I lurve roses. If you get an older variety suited to your climate (no idea, I've only lived in zone 9) they will grow like weeds.
Go to your local nursery or even the plant section of your home depot. What would you like in you roses? Color, scent, etc. This will narrow it down some.
Plant roses in full sun, don't be affraid of aggressively trimming back during spring (get tons more blooms this way and enjoy!
It's also pretty easy to root roses, so with patience and some initial investment you can create a bunch more plants. :)
