Daylily Rust
Daylily rust is a highly contagious fungal disease that disfigures daylilies. Currently, it is a larger problem in USDA hardiness zones 7 or warmer, but it is important for anyone who grows daylilies to be aware of it. In doing some research on one of my favorite plants, Patrinia scabiosifolia, I discovered that it's the alternate host for the fungus. So now I'm faced with the dilemma of whether to eliminate the patrinia or not. One of the best Web sites for information on this disease is Daylily Rust Information Page provided by Sue Bergeron. There is lots of information, photos, and links.

Caterpillars
A real butterfly garden requires not only the bright flowers that feed the butterflies but also the host plants that provide sustenance for the caterpillar stage. Butterfly experts stress that gardeners can best serve butterflies by providing the food plants needed for the larval stage. Caterpillars in the Field and Garden, by Thomas J. Allen, Jim P. Brock, and Jeffrey Glassberg (Oxford University Press, 2005; $19.95), is the first field guide to the butterfly caterpillars of North America. Each species section includes photos, key physical features, abundance, habitat, and major host plants. There is also a section on gardening for caterpillars and butterflies.
