Water Hyacinth
Echhornia crassipes
If you are a beginner in ponds, nothing will inspire you more to try your hand at water plants than the Water Hyacinth. They are pretty much foolproof because you simply float them in the water in your pond. The leaves are dark green and shiny with a swollen "float" in their stems, and they will bloom during June, July, and August. When they bloom they produce strong spikes bearing Orchid-like blooms in a nice lavender color, with a dark purple "eye" enclosing a yellow center.

The flowers normally only last one day. Given the right water conditions, Water Hyacinth will produce new plantlets in what seems like over night. The babies will just suddenly appear on offshoots from the mother plant. When each baby has its own set of roots, you have the choice of   leaving it attached or simply break it loose from its mother plant and move it to a different area of the pool.

HOW TO GROW

With a height of 6 to 8 inches. Water hyacinths are one of the best water purifiers around. In fact, there has been a lots of experimentation using them to clean up chemicals in the water on commercial sites that have been accidentally polluted. Once the root system becomes saturated with the pollutant or chemical they throw the plant away.

 In the water garden they are heavy feeders, they can suck the nutrients out the pond to the point where it will competitively eradicate floating algae in a relatively short period of time. No water garden is complete without this fast growing, nutrient eating plants. Some sources recommend once a week removing the plant from the pond and swishing the roots in a bucket of water, to keep the plant clean and healthy looking. However, in large ponds with many plants this idea may not be practical. Hardy to zone 8.
