Plants for ground cover - under trampolene or difficult areas

All the details

Ground cover geranium plants -used them under the trampoline to stop weeds - but they are great as ground cover in all areas I think they are this variety but I am not sure Geranium macrorrhizum ‘Ingwersen’s Variety’ Removing them because we no longer have the trampolene and I want to place a greenhouse in this spot - but it seemed a shame to throw them away. They are really easy to grow - you won't kill them and can easily be pulled up if they get too invasive. The frogs and other wildlife also love the ground cover I am in most of the week and would ask that you bring containers such as large flattish cardboard boxes for the plants - they will be easy to dig up
