Any ideas for a lawn replacement ground cover that you can comfortably walk on? For example, ivy and vinca will grow like crazy in my shady backyard, but not very comfortable to walk on in bare feet. Pachysandra and ajuga grow quickly as well, but too tall to really be replacement for grass. Need something that is low growing like creeping thyme but for a full shade location in Zone 6. Most of the backyard is already perennial beds and hardscape. I share the backyard with several other people so trying to compromise. Left to me I would put in more beds! Thx....
