A relative of the florist’s beloved Gysophila paniculata, creeping baby’s breath is a trailing form under 8” tall and has larger, single flowers that are borne in flat clusters. In a couple of years the plant forms a dense mat with slender gray leaves and is particular attractive when cascading over a wall. The plant is equally useful as an edger, in containers, or in a rock garden where its need for well-drained soil can be met. It tolerates heat well but not wet feet. The generic name Gypsophila refers to the fact that the plants like gypsum indicating that they prefer a high pH (basic soil). Trailing baby’s breath is less picky in this regard than G. paniculata and tolerates acid soil.
