Butterflies in the garden The Secret Garden in Elk Grove hosts its annual Butterfly Fest over two weekends, September 1314 and 2021. Visitors can take guided life cycle tours at 11 am to see Gulf Fritillaries move from egg to caterpillar to chrysalis to orange-winged adult. Alongside the butterflies, there's face painting, a coffee cart, and a fall plant sale with perennials discounted for would-be pollinator gardeners.
