Lycoris sprengeri (), also named Matsu stone garlic (), are pink with a blue tint. The leaves are 58 cm long and 1.3 cm broad. The cup-shaped flowers are elegant. The pollination period of Lycoris sprengeri is a month earlier than Lycoris radiata. In the Matsu Islands, Lycoris sprengeri occurs only in Dongyin and Xiyin (Siyin), and is already classified as a conservation species. From June to August, dotted Lycoris sprengeri creates a picturesque landscape as swayed by the wind. Lycoris sprengeri is broadly distributed throughout Mt. Shiwei (), Mt. Enai () in Dongyin, Dongao(), Qingshuiao (Cingshueiao) (), and Dragon Boat Sands () in Xiyin (Siyin). Scilla scilloides Scilla scilloides (), within the Liliaceae (), bears a terminal raceme of pink small flowers. It is said to resemble a fox's tail. The shape of Scilla scilloides is elegant. In Northern Taiwan, Scilla scilloides occupies habitats under 700 meters high in a small amount. From July to August, Scilla scilloides can be easily spotted on the open hillsides or fields along the roads in Dongyin and Xiyin (Siyin). Scilla scilloides also can be found in Nangan (Matsu Island), but the majority is in Dongyin and Xiyin (Siyin). NTU Professor suggests Scilla scilloides be a listed candidate for 'Township Flower' in Dongyin. Dianthus superbus var. longicalycinus Dianthus superbus var. longicalycinus (), within family Caryophyllaceae (石竹科), simply looks like wild Dianthus (石竹). Dianthus can be recognized by their rather ragged edges of petals and long calyxes connected to petals. Most flowers are pink and blue. The huge amount of Dianthus gives an impression of the endemic plant in the Matsu Islands. However, Dianthus, though not common, can also be found in Taiwan. The pollination period of Dianthus is long, from early summer to winter. The blossom period lasts for half a year. They grow in a large quantity in the wild and along the roadsides in Dongyin. Dianthus is also to be found. Heteropappus ciliosus Heteropappus ciliosus has not been found in Taiwan. Due to the special geography of Dongyin in proximity to the Mainland China, Heteropappus ciliosus is one of the valuable assets. Heteropappus ciliosus grows snugly close to the ground. The colors of the tongue-shaped flowers are violet, pink and white, with yellow tube-shaped bulb in the middle, while the violet and pink ones are more commonly seen. The annual blossom season of Heteropappus ciliosus is when the terns () emigrate
