Four speedwell species are important weeds in the Pacific Northwest:
• Ivyleaf speedwell (Veronica hederaefolia L.)
• Persian, birdseye, or winter speedwell (Veronica persica Poir.)
• Creeping speedwell (Veronica filiformis Sm.)
• Purslane speedwell (Veronica peregrina L.)
The first decision to be made is whether to incubate eggs naturally or artificially. Natural incubation uses a broody hen to incubate eggs by sitting on them in a nest. Broody hens, when available, work best for small clutches of eggs.
Yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria
