Water Lilies are the only introduction I made of plant species not found on the property. Even these lilies don’t follow my original intent. Planted in weighted pots, their root systems become so massive during the summer that they rise to the surface to float about as islands. The root masses have totally engulfed the pots along with several bricks that I tied on in an attempt to keep the roots on the bottom. Several species of aquatic plants have colonized the islands and survive the winter immersion while waiting for the islands to pop back to the surface in summer.
Water Lily flowers always fascinated me as a child. I would spend hours staring at them. This year, you have to view these white flowers early in the day to catch their brilliance. Tree pollen is falling so heavily that white quickly turns to yellow as the day goes on. The bud to the left has collected several rings of pollen already. The pollen forms a skin on the water’s surface that remains until a rain causes it to sink to the bottom of the pool.
I put in some pots of native aquatic plants when the water garden first filled. Since then, a variety of seeds has arrived to add diversity to the pots. The actual lip of the pot is about an inch below the water surface. Accumulation of moss, roots and organic debris has raised the soil level above the water line and doubled the diameter of the original pot.
Common Milkweed arrived on the scene just a few years ago. Although I have several stands of milkweed around the yard, the plants growing next to the

At the end of the labium is a set of curved hooks that trap the prey and hold it while it is consumed. A pool full of dragonfly nymphs can easily cut down the number of smaller organisms.
Another predator with a never-ending appetite is the Red Spotted Newt. These guys will feed on any animal matter, dead or alive, that is small enough to swallow.
In time, larger predators arrived. The Common Water Snake feeds on the larger pool inhabitants, including other predators.
Bullfrogs have massive mouths and will try to eat anything that moves. When Bullfrogs move into a small pool, they quickly consume the smaller frog species. I’ve tried removing predators in an attempt to keep the pool in an earlier stage of development, but have decided that type of activity is not practical. The

Air is carried by the Water Boatmen as a film covering the body surface. This gives the bugs a shiny appearance and makes it difficult to view body details. They stay submerged by anchoring to stationary objects and periodically come to the surface to exchange stale air for fresh.
Great Blue Herons have eaten all of the goldfish, so the 100 gallon tub has lost its top predators and algae eaters. Algae is a quality food item and where food exists, something will come along to eat it.
Since a population of new predators has not yet had a chance to colonize the tub, the Gray Treefrogs have a safe place in which to lay their eggs. New egg clusters are placed almost daily.
The tadpoles develop quickly and it won’t be long until they are growing fat on the algae. I’m looking forward to seeing what other changes this year brings to my
