Some plants to try:
Lemongrass (Cymbopogon citratus) is a familiar herb grown in bogs, wet garden soil and along the edges of shallow water gardens. It also grows well in ordinary, damp soil. This tasty herb grows up to 4 feet high and equally as wide and is known for the fleshy base of the grass stalks that grow on top of the ground.
Cattails (Typha latifolia) Believe it or not, all parts of the cattail are edible and delicious, from the young shoots, which are eaten raw, to the pollen, which is added to biscuits or pancakes
Water mint (Mentha aquatica) grows on the edges of ponds and water gardens. The leaves and flowers are delightful flavorings for ice cream, mint juleps, syrups, and sorbets.
Watercress (Nasturtium officinale) requires running water for growth. It floats on the surface along the edges of moving streams, with tiny rootlets that reach into the rocks and soil. It is delicious when added to salads, dips, and sandwiches.
Please note: Not all plants may be available or grow in all parts of the country at all times of year.
