True bog and marginal plants like royal fern ( Osmunda regalis) and cultivars of Iris laevigata can flourish where water levels fluctuate between standing water and moist soil.
While most of the roots inhabit the upper layers, deeper ones can reach down to access water during dry spells. For the best flowerbed ideas, you may find mounding their beds is often a good solution. Moisture-lovers require damp soil but need good drainage for long-term survival.
