A hoop house, covered with black mesh, entering and exiting through double-screen doors is the basic set-up: inexpensive and nice. Raised beds support a variety of nectar plants and many other donated plants creating a nice border mix.
 This monarch butterfly benefited from a purple coneflower inflorescence.An outdoor butterfly garden bed completes the display. Great fun, indeed.
We'll be breaking ground in a couple of weeks for a new Butterfly Garden installation at the Botanical Garden where I work. We're excited about adding lots of host plants for butterfly caterpillars in addition to the nectar plants!
