Edgewood County Park and Natural Preserve is a 467-acre protected area located in San Mateo County and is best known for its spring wildflower displays. It has variety of habitats of woodlands, coastal shrubs, wetlands and grasslands perfect for hiking or walking dogs. There were great amount of poison oaks on the side of the trail that had to be looked out for. The overall trail difficulty was moderate since there were some big slopes in between. There were great amount of new flowers we learned at this field trip. The tidy tips, pineapple weed, blue eyed grass, shepherd’s needle were some of the flowers we have encountered.

We left on time around 1pm at the parking lot. This field trip was quite a drive that it took longer than the others. There was a giant hill right at the beginning of the hike that completely burned my thighs. There were many poison oaks on the side of the trail, so we managed to stay inside of the trailroad. We saw many wildflower plants that we haven’t seen in the previous field trips. My favorite one was the pineapple weed because it really looks like a mini pineapple. That was the first time that I actually agreed on how they named the plant. I wish the weather could be better since it was cloudy all the time.
