I’m in central Denver & recently purchased an older home on a corner with a 20’ long by 2’ wide “hell strip” on either side of the sidewalk. It is due south facing, & gets full sun. For the strip adjacent to my yard (but separated from my turf by a graduated 30” tall 100 yr old stone wall), I plan to install a drip line to provide water. Across the sidewalk, I’m not sure if or how this will be watered- so uncertain if anything can ever grow in this strip (which happens to be only 12” wide, abutting the curb) I would like to use plant cover (vs rock) in front of my lovely old stone wall, but am hoping for something that is sturdy (some foot/dog traffic inevitable), relatively low maintenance, drought resistant- and spreads relatively quickly to completely fill in the space. Prefer, as well, that it not grow more than 2’ tall & fully hide the stone wall. Might you be able to offer a few suggestions of plants/flowers we may want to look at that might work well in such a space? Is anything likely to grow in the more narrow strip if not accessed permanently by a water source? Thank you!
