Today, the hyacinth is found in more than fifty countries on five continents.
A curiosity of the water hyacinth is that, in floating plants, the flower heads or inflorescences bend downwards one or two days after flowering,, submerging themselves in the water.
Careful now, be sure water hyacinth is the only plant they'll eat.
However, while I'm certainly no chemist, very few if any of these uses are presumably appropriate when the water hyacinth is heavily contaminated.
For instance, on page 140, the botanical name for the water hyacinth is given as "Eichornia crassipes"; the more usual spelling is "Eichhornia crassipes", as used on page 210.
The water hyacinth is a plant that removes pollutants from the water, which is why it isn't feasible to dredge it out, chop it up, and use it for forage or mulch.
I had heard that water hyacinth is a big problem in the lake.
The matted roots of the floating water hyacinth is ideal for this.
The air itself, carrying a salty whiff of high tide and sweet hyacinth, is ripe with possibility.
The water hyacinth is no longer covering a disproportionate part of the lake and its coverage is back to its "normal" level of 5% or less.
