I would plant on the side that has the best sun. Or you can plant on both sides of the wall if the wall is tall enough. How tall is your wall? Also not all climbers are lax enough to spill over a wall. I have Eden and think it would spill, but I dont know abiut Zephy.

The very best spilling, cascading, draping roses photos I've seen were on Hoovb's blog of her beautiful pink Bishop's Castle roses planted along a low wall beside steps in her garden. Then, sometime later, I saw one again here when I discovered Garden Web. She is in a much warmer zone than I and it's a trick to get roses to do that much cascading here, so I don't know anything about how this works. Your topic brought these pic to mind. It sounds like this is the look you're after.

Oh what beautiful pictures that is what I was picturing but then looking up google images of climbing roses spilling some looked like giant octopus arms and super sloppy...these examples are perfect.

Here is the eden...the back side is north facing and both sides get mostly sun with some shade. Here I either try to train it from behind to cover and spill over the picket fence (which is ugly and there for safety for our little kids.) Or plant in the side and train up and across. Also I live in zone 8. You can see I recently planted the eden but again am wondering if I should move it.

i was certain I wanted them to spill over but now I’m feeling very unsure what I should do I’m nortoriois to second guessing myself.. maybe if I grow the eden on the back and it gets huge across top of wall I can remove ugly fence as thorny roses would deter little boys from trying to play on top of the wall right?

Hi Candace, I would leave Eden where you have it, and train the canes out along the fence on either side, allowing them to spill down at the ends. I can confirm, from personal experience, that Eden will bow down and still bloom -- at least to the level of its roots. But as Cynthia notes, roses whose canes drape too far below horizontal can have issues (circulation problems? Anyone know how to explain this?) I'm not sure if Eden would enjoy hanging straight down over your fence -- it probably needs to go up or along the fence for at least as much distance as it will drape down. Imagine sort of fanning it out along the fence in both directions. Below is a picture of mine (own root, I think four years old now) which, last summer, was draping over my five-foot fence (at right) and hanging into the garden. This year it looks super awkward, as I chopped some of the canes leaning into my garden due to a midge issue, and encouraged it to sprawl in front of the alley to discourage a public urination issue (yeah... gross). But I think this picture will help you visualize the possibilities for yours. I would not remove the fence, as it will give the rose a bit of support.

P.S. I think this would look great with Eden spilling from above and another rose planted at the foot of the wall with lavender or something.
