They could be rooted but unless you see actual roots on the bottom of the stems now those leaves that are developing are just using the stored energy in the cane itself. If you'd like to try rooting them get a clear plastic cup and punch a hole in the bottom. Fill it with potting or seed starting soil and poke a hole in the center of the soil with a pencil. Take the stem and very gently scrap off just the outer green skin with a knife or scissors exposing the white inner layer. Dip that into some type of rooting hormone and stick it in the hole you made in the soil and gently pack the soil back around the stem. Water it, place it in the sun and keep it evenly moist but not soggy wet and wait. It may take a few weeks to see any roots in the bottom of the cup. If the stem starts to turn brown or black at the soil line that usually means it's rotting and didn't take. If they do root they will grow and bloom like any rose. Good luck!

Seil, thank you for your advice. I'll try it and will report sometime in the future what, if anything, happened. I have rooted cutting before but they were easy things, such as Jade. I didn't think it would work with roses, which I've always thought of as "difficult to please".

It isn't really any different than rooting any other plant. Roses are survivors and given any chance will grow! I hope it works out well for you!
