All the plants have taken well. I've already planted this plant, which is quite invasive, and that's what I'm looking for to hide something.

Planting and care

Campanula poscharskyana is planted from February to April or from September to November, in full sun in areas with cool summers and in partial shade where heat quickly dries out the soil. It prefers a light or stony soil, neutral to alkaline, remaining slightly moist but perfectly drained in winter. In heavy soil, incorporate gravel and plant on a slight mound; in a gap in a low wall, mix garden soil and compost without blocking water drainage. Water during the first summer as soon as the soil dries out deep down. A well-rooted plant tolerates short dry spells, but flowers for less time if they persist. Prune spent flower stems after the main flowering to thicken the carpet and limit self-sowing. Pull up rooted stems that grow beyond the intended area. Division is carried out in spring or September.
In a pot, choose a wide container with drainage holes and allow the surface of the compost to dry out before watering again.
