Evaluation of the potential of pontederia
parviflora Alexander in the absorption of copper (CU) and its effects on tissues.
I have put some Pontederia
cordata (pickeral weed) in the bog garden from the pond.
It is host- specific to aquatic plants in the genera Eichhornia and Pontederia
(Adis & Junk 2003, Adis & Victoria 2001); however, different populations generally only have access to either E.
Most were obtained from an onsite nursery, but three species (pickerelweed, Pontederia
cordata; softstem bulrush, Scirpus validus; and giant cutgrass, Zizaniopois miliacea) were imported from a Florida nursery (Duckworth-Cole, Inc.

Presently the surface of my large basket of Pontederia
in the pond is simply awash with developing tadpoles and hopefully many of them will survive to grow into fully fledged frogs and toads - one of the best natural predators of slugs.
The leaves of plants such as arrowhead Sagittaria latifolia, flowering rush Butomus umbellatus, and pickerel weed Pontederia
cordata grow near the surface of the water and their flowers extend above it.
cordata, or pickerel weed, will grow in water up to 9ins deep.

By the twentieth of August, everywhere in woods and swamps we are reminded of the fall, both by the richly spotted Sarsaparilla leaves and Brakes, and the withering and blackened Skunk-Cabbage and Hellebore, and, by the riverside, the already blackening Pontederia
