Growth Rate

Under a moderate growth rate, Eleocharis acicularis intensifies development throughout Spring, Summer, and Fall. During these seasons, verdant blades proliferate, leading to a denser mat. As growth peaks in Summer and gently subsides in Fall, a discernible surge in height is observed. This growth pattern, mirroring environmental cues and climatic conditions, results in elegant brush-like tufts, characterizing the plant's form.
