I need to create an evergreen privacy screen ten feet wide by 30” tall. I live in Chilliwack, so am thinking zone 7. Full sun, in windy location. Love sedums and sempervivums. I thought I might build three frames out of 2x6 (to sit side by side - more manageable and can reposition to cover most crucial three feet in case of winterkill) plant them with sempervivums or sedums on one side through mesh (and dried moss to hold dirt) and make the back of wood, let it grow this summer horizontally (would use a temp screen this year) then put it vertical in the fall or spring to leave it there permanently, would this work? I have sedums and sempervivums in pots on same deck, they have survived winters fine, (except for this winter the sempervivums not so much!) though conditions in the wall might be a bit more extreme. I also have visions of the dirt washing away gradually. Any ideas? I have already considered and discarded many vines grasses and shrubs growing in pots but couldn’t come up with anything that really worked. Closest I got was C armandii planted in the ground below, but my deck is second story, it isn’t guaranteed to get that high. Also ivy, kind of boring, planted in pots on the deck growing up trellis. Would have loved Pieris japonica lined up in row of tall pots but apparently potentially toxic to cats. Might hedge my bets and plant one frame each of ivy sedum and sempervivums. One cedar in a 20’ high hedge died and left me in view of bank of second floor apt windows with snoopy neighbours. Will replant cedar but will be years to reach height. Thanks for any advice!
