👉 Roellobryon is a type of plant that grows in rocky or sandy soil, often found in coastal areas and near water bodies. It has a distinctive rosette-like appearance due to its fronds that are arranged on long stems, which can be up to 10 feet (3 meters) tall. Roellobryons are commonly used for their edible seeds, which contain a high protein content and are often eaten in salads or added to soups.
