P. repens is an interesting specimen to demonstrate the metamorphosis of chloroplasts (outward of cell) to amyloplasts (inward of cell) if studied with a microscope.

Under its synonym Elatostema repens it has won the Royal Horticultural Society's Award of Garden Merit.[5] E. repens var. pulchrum has also won the award.[6] Procris repens is also commonly referred to as Pellionia repens, although this name is now regarded as a synonym of Procris repens.[7]
