European Beachgrass

Ammophila arenaria

European beachgrass (Ammophila arenaria) is a species of dune-building grass found along the coastlines of Europe and North America. It is an important stabilizer in sandy regions, forming large egg-shaped clusters to keep sand in place and prevent erosion. Its blades are coarse and deeply-ridged, growing up to 45 cm long with thick, fibrous roots. Its off-white flowers grow up to 50 cm tall with a spike of brownish-yellow seeds. Its strong adaptability makes it an essential plant for sandy coastlines and barrier islands, playing a vital role in the coastal ecosystem.

watering

Scarlet Ammannia (Ammannia coccinea) should be watered once a week with about 1/4 to 1/2 inch of water. Watering can be done every 3-4 days during periods of extreme heat. Make sure not to over-water, as this can kill the plant.

sunlight

Scarlet Ammannia (Ammannia coccinea) prefer a moderate amount of sunlight as too much can scorch them. Therefore, they are best suited to grow in an area that receives direct sunlight for 4-6 hours daily.

pruning

Scarlet Ammannia should be pruned regularly throughout the growing season throughout the year. Prune in the spring and summer, and minimize pruning during the winter months. Prune back any stems or leaves that show damage to keep the plant looking healthy. Remove up to 1-third of the top growth before flowering to promote more flowering.
