Ground-covering plants have become especially popular with aquascaping. A dense, vital carpet of Hemianthus callitrichoides "Cuba" or Glossostigma elatinoides is impressive and brings a lot of atmosphere to a layout. Meanwhile, many different species of ground-covering plants have become available, like e.g. Eleocharis sp. "Mini", which is used to create dense lawns with fine leaves, or Marsilea crenata for colourful plant carpets. They provide aquascapers with manifold options for attractive foreground layouts.
Ground-covering plants differ in their speed of growth, their colours and their requirements. You have many options, from easy-to-keep plants to those whose cultivation is very difficult.
Some easy-to-cultivate ground-covering plants are e.g. Glossostigma elatinoides or Micranthemum sp. "Montecarlo". Species of the genus Marsilea are also quite undemanding, however, their colour is of a far darker green, and young leaves are beige to brownish.
Eleocharis sp. "Mini" or Eleocharis parvula are two different hairgrasses. Both are suitable for creating very low-growing lawns in a layout.
