Purple laver + Narrowleaf cattail

Porphyra is a cold water seaweed that grows in cold shallow sea water. More specifically, it is a foliose red algal genus of laver, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea). There are considered to be 60 to 70 species of Porphyra worldwide and seven in the British Isles.

Typha angustifolia L., (also lesser bulrush or narrowleaf cattail or lesser reedmace), is a perennial herbaceous plant of genus Typha. This cattail is an "obligate wetland" species that is commonly found in the northern hemisphere in brackish locations. The plant's leaves are flat, very narrow (¼"-½" wide), and 3'-6' tall when mature; 12-16 leaves arise from each vegetative shoot. At maturity, they have distinctive stalks that are about as tall as the leaves; the stalks are topped with brown, fluffy, sausage-shaped flowering heads. The plants have sturdy, rhizomatous roots that can extend 27" and are typically ¾"-1½" in diameter.
