The purple colour underneath Alternanthera
''roseafolia'' (Pink) leaves provides an effective contrast to the many green
plants in an aquarium - particularly when planted in groups. Good light
encourages the leaves to turn red. Most Alternanthera species
are difficult to grow, but this one is relatively undemanding. Easy to
propagate by nipping off the terminal bud and planting it in the
bottom. This also makes the mother plant more bushy, because more side
shoots are formed.
