Wildflower Walk at the Native Seed Farm

Join us for a leisurely walk through the Native Seed Farm to see our wildflower plots in bloom. We’ll stick to the hard-pack roads around the fields – bring your camera to take photos or simply enjoy the scenery. You’ll learn about the plants we grow and why we grow them, and see pollinators in action. We’ll finish the activity with a walk around the other fields at the farm so that you can see our grasses, woody plants and perennial forbs up close.

Slow Paced Hike Exploring Summer Wildflowers in Bloom

Join us for a slow-paced hike in Irvine Ranch Open Space, specifically Limestone Canyon. Our pace will be around 2.5 MPH for this 5.5-mile hike with an elevation gain of about 400 feet. Slowing our pace will encourage us to experience the land with all of our senses. We will be able to see, smell and hear the sounds of the Open Space! If you enjoy recording your sightings of wildflowers, please download the App called SEEK (INaturalist) prior to reaching the Augustine Staging area. We will use SEEK to identify native and non-native wildflowers. Our hike will take us along Limestone Canyon and then over to Dripping Springs. Dripping Springs is a year-round spring where we will encounter water that is expressed through the side of a vertical rock face. Due to shade and moisture, we will find that the plants in Dripping Springs are very different from the plants and flowers found in the meadow area of Limestone Canyon.
