Lemon Water Hyssop (Bacopa caroliniana)

Water Hyssop has bright green clusters of leaves on erect branches that form a thick plant that can grow submerged or above the water as a marginal accent. It produces soft purple or blue flowers that are ball-shaped. Requires temperatures of 55 to 80 degrees.

Cabomba (Cabomba caroliniana)

Cabomba has lacy, fan-shaped leaves on long submerged stems with very tiny white flowers. It does not tolerate too much water movement, and needs water temperature between 64 and 77 degrees to thrive.

Hornwort has branched stems bearing crowded whorls of dark green bristly foliage giving a bottle-brush effect. In autumn, stems drop to the bottom to over winter.

Anacharis (Egeria densa)

Anacharis has narrow, dark green leaves, one-inch long, that are produced in whorls on branching stems ranging from one to seven feet in length. Tiny white flowers are produced at the water's surface. Anacharis is the most popular and the hardiest of the underwater grasses.

Deep green mint-like leaves which produce lavender flowers at leaf joints when the plant grows above water.

Green branching foliage that sometimes turns red.  Submerged this makes a great underwater groundcover.

Reddish-brown foliage and stems gives contrast to other submerged plants.

Foxtail (Myriophyllum hippuriodes)

Foxtail is reddish-brown in color with delicate hair-like leaves that cover each stem. It makes an excellent fish spawning material as well as aquatic filter.

Z9-11

This feathery plant is always a favorite and can be grown either as a submerged plant or as a marginal.  It is not a true oxygenating plant as it loses its leaves below the water line.  It spreads out like a blanket on rhe surface.
