Cerastium diffusum, the fourstamen chickweed or sea mouse-ear, is a species of flowering plant in the pink and carnation family Caryophyllaceae. It is an annual herb, to 30 cm.high, occurring in western Europe and northern Africa. Found mainly in coastal areas of Algeria, the Baleares, Belgium, Corsica, Denmark, France, the Faroe Islands, Germany, Great Britain, Ireland, Italy, Libya, Morocco, Netherlands, Norway, Portugal, Sardinia, Sicily, Spain and Sweden. The flowers have 4, (or seldom 5) petals, 4 or 5 stamens appearing between March and May. The petals are much shorter than the sepals. The leaves are opposite, (sessile) without petioles and the sepals and bracts are all green, without pale margins. The fruit petioles are erect and diffuse at maturity.: 490 : 52 There are 2 known Infraspecifics; Cerastium diffusum subsp. diffusum Cerastium diffusum subsp. gussonei (Tod. ex Lojac.) P.D.Sell & WhiteheadIt was first published in Synopsis plantarum 1 on page 520 in 1805.
Sea mouse-ear is fairly disease-resistant and usually not prone to illnesses. Still, it can be affected by pests and diseases present in its surroundings, and these issues are typically not severe. For care, this plant needs moderate maintenance. It should be pruned regularly to keep a neat appearance and support healthy growth. Fertilizing can also aid in encouraging flowering. Sea mouse-ear is suitable for anyone with an outdoor area such as a garden or patio and does not require extensive care experience. When grown indoors, it may demand more attention.
How to keep Cerastium Diffusum.
Light
Sea mouse-ear is a sun-loving, perennial herbaceous plant native to open habitats and commonly found in meadows and grasslands. It prefers full sun but can tolerate partial sun conditions.
Water
Sea mouse-ear is native to coastal areas and flourishes in environments with moderate moisture levels. It grows best in soil that remains consistently moist without becoming waterlogged and typically requires weekly watering. Its strong root system efficiently utilizes water, showcasing its ability to adapt to both wet and slightly drier conditions.
Temperature
Sea mouse-ear can tolerate a broad range of temperatures, but its distribution can still be restricted by specific combinations of moisture and heat. It performs best in warm summer conditions with sufficient rainfall or watering. Extended stretches of cloudy, rainy weather, as well as prolonged high temperatures, raise the likelihood of Sea mouse-ear dying. In winter, proper protection from cold can improve the plant's chances of survival.
Fertilizer
Typically, a single fertilizer application in spring is adequate for Sea mouse-ear, though additional feedings can boost growth to its fullest. Fertilize every month to every month and a half. Fertilization improves the leaves' appearance and function, maintaining uniform color and a healthy texture. It also encourages root development and enhances nutrient uptake for lasting plant health.
Pruning
The sea mouse-ear plant benefits from selective pruning, ideally done from early to late spring to remove any dead stems. Light pruning encourages growth and reduces the risk of disease. Trimming spent flowers regularly helps promote continuous blooming. Be sure to always use clean, sharp tools to maintain the plant's health and vigor.
