Sagittaria Sagittifolia est une plante dot\u00e9e d\u2019une grande plasticit\u00e9 et capable de s\u2019adapter \u00e0 des conditions environnementales vari\u00e9es. Elle croit dans un milieu aquatique dont la profondeur se situe jusqu\u2019\u00e0 un m\u00e8tre. S\u2019il est vrai que la plante pr\u00e9f\u00e8re une faible profondeur (conditions dans lesquelles elle fera le plus de feuilles a\u00e9riennes), elle garde une grande fertilit\u00e9 jusqu\u2019\u00e0 0,5 m de profondeur. Sa profondeur optimale se situe donc entre 0 et 0,4 m de profondeur. A basse profondeur, la plante compte nettement plus de feuilles a\u00e9riennes que de feuilles flottantes, plus efficaces pour la photosynth\u00e8se. De 0,5 \u00e0 0,8 m de profondeur, ces deux types sont en quantit\u00e9 \u00e0 peu pr\u00e8s \u00e9gale. Tandis qu\u2019au-del\u00e0 de 0,9 m, les feuilles flottantes pr\u00e9valent sur celles a\u00e9riennes. Elle poss\u00e8de un \u00e9cotype terrestre en cas de s\u00e9cheresse, bien que dans ce cas, les plantes se maintiennent \u00e0 l\u2019\u00e9tat v\u00e9g\u00e9tatif (ne font pas de fleurs). Sagittaria Sagittifolia tol\u00e8re les eaux dont le pH se situe entre 7.0 et 8.5 environ. Elle n\u00e9cessite un \u00e9clairage intense<\/p>\n
