My theory: In sun the metabolism of the WH is so high it quickly eats
everything and starts to starve/yellow. ~ jan

I notice that the water hyacinth in my main pond is not nearly as

pool hyacinths are deep green and are even flowering while the main
pond hyacinths are lime green - yellow.

The pool is partly shaded by some grasses nearby but the main pond
gets full sun.

Is it possible that WH wants only partial sun?
