I worked at this park a decade ago, and I wondered which plants I would remember. I cheated in a couple cases; I had to read the signage, although I did recognize the large-headed sedge, Carex macrocephala, scattered among the grasses.
Here it is, showing the large fruiting spikes. It's nice to find a plant whose name makes sense in both languages. Especially a sedge.
This one is entire-leaved gumweed, Grindelia integrifolia. Its name refers to the sticky white latex that coats the bracts that surround the flowers. Yes, it's very sticky.
This sprawling, sage-bushy, somewhat succulent plant is silver burweed, Ambrosia chamissonis, also known as Franseria chamissonis. It is fragrant, smelling like cinnamon or nutmeg if crumpled.
A final view of the dune. In the foreground is beach pea, Lathyrus japonicus. In the mid-ground, somewhat bluish, is dunegrass (Elymus), and interspersed are splendid water- and weather-worn logs. The logs are important to dune ecology, I would imagine, for the physical structure and microhabitats they provide. Someone should look into that. (I bet someone already has.) I, in the meantime, will study the tide tables.
