October 11th – On the way to work on the canal Walsall Wood, I noticed something one doesn’t normally see until early spring: This floating root, probably disturbed by Canal and River Trust efforts to remove the floating algae, is a rhizome of the water lilies that are so profuse here.
This remnant of the summer plant generally sinks to the canal bottom during winter, and when the water warms in spring, it becomes buoyant, floats with other detritus and then takes root, and when rooted, will grow that season’s lilies.
It’s a curious mechanism that actually works very efficiently.
