A perennial of the Campanulaceae family, this lobelia could not be determined with certainty at the species level. Its habit and general characteristics evoke the mat-forming lobelias of the southern hemisphere, similar to Australasian or Andean species cultivated in rock gardens.
It forms a very tight and dense creeping carpet, spreading between the stones of a rock garden, with a foliage height of only 3 to 5 cm. The leaves are remarkably small, rounded, dark green to slightly bronzed, borne on reddish to purplish stoloniferous stems that are an immediately visible distinctive feature. This contrast between the dark stems and green foliage is particularly striking.
The flowers, solitary on long slender peduncles standing clearly above the carpet, have five spread lobes of a pinkish white to pale pink, with a tube slightly tinged with a deeper pink. The overall effect, with these light flowers suspended above the dark cushion, is of great delicacy. The flowering period observed in cultivation is in spring and early summer.
In cultivation, it seems to enjoy well-drained but fresh soil, between stones in a partially shaded to sunny exposure. Its exact hardiness remains to be specified according to the origin of the plant.
