Crystal Cove State Park
April 23 @ 9:00 am - 2:00 pm
Join us on a hike along the bluffs and beach at Crystal Cove State. These areas represent some of the best coastal bluff scrub in Orange County. Coastal bluff scrub is a diverse shrub-dominated habitat strongly dependent on marine influence. The habitat supports some the most diverse assemblages of rare plants in Orange County.
After all the rain, there should be a lot of wildflowers. If the timing is right, we should see extensive stands of Orange County Turkish-rugging (Chorizanthe staticoides subsp. chrysacantha).
We will start on the bluffs north of the Historic District, then walk down along the beach. We should see several rare plants including aphanisma (Aphanisma blitoides), Pacific saltbush (Atriplex pacifica), red sand-verbena (Abronia maritima), and possibly vernal barley (Hordeum intercedens), California boxthorn (Lycium californicum), Coulter’s saltbush (Atriplex coulteri), and many-stemmed dudleya (Dudleya multicaulis).
From there we may move locations, depending on time, to the Historic District to see Davidson’s saltbush (Atriplex davidsonii), only recently rediscovered after not being seen in Orange County for 85 years. Or we may head to the south end of the park to see if we can find the only Orange County occurrence of San Diego fiesta flower (Pholistoma racemosum) and an undescribed ground cherry (Physalis sp.) known to occur in Orange and San Diego Counties.
