Barbara Rice found a nice group of Leopard Lilies, Lilium pardalinum. These beautiful lilies are also called Tiger Lilies.
You should never pick these wildflowers, as the flower head develops the seeds the plant needs for the following year.
Here's a close-up of this beautiful native with a Swallowtail butterfly feeding. This photo was taken by Peter Baye and is included in my beautiful book, Mendonoma Sightings Throughout the Year. It also shows that native plants feed native critters.
Thanks to Barbara and Peter for allowing me to share their photos with you here.
