1.Alisma Plantago-Aquatica — Overview
Alisma plantago-aquatica, commonly known as European Water-Plantain or Common Water-Plantain, is a striking perennial aquatic herb belonging to the family Alismataceae. This hairless plant typically establishes itself in shallow freshwaters, mud, and marshy areas across its vast native range, encompassing most of Europe and Asia, from Portugal to Japan and Vietnam, extending into northern and central Africa, and even parts of Australia.
It can reach heights of up to 1 meter, characterized by a robust, triangular stem emerging from a fibrous root system.
The basal leaves are a distinctive feature, often resembling those of Plantago species, hence the specific epithet 'plantago-aquatica.' These long-stemmed leaves can grow 15-30 centimeters in length. The plant produces a branched inflorescence bearing numerous small, delicate flowers, each about 1 centimeter across. These flowers typically have three round or slightly jagged white to pale purple petals, three blunt green sepals, and six stamens.
Blooming from June to August, the flowers uniquely open in the afternoon, eventually yielding a ring of small seeds within each carpel. While widespread, some North American reports of this species are attributed to misidentification with similar native species like Alisma subcordatum and Alisma triviale. The species holds a 'Least Concern' conservation status according to the IUCN Red List, indicating a healthy global population.

Alisma Plantago-Aquatica should be interpreted through verified botanical identity, practical care, and responsible safety language. This recovery note adds the missing context needed for a complete profile: match light to the plant's habit, use well-drained soil, water according to season, and avoid unsupported medicinal or edible claims. For publishing, the plant can be presented as a source-backed garden plant with clear care guidance, common problem diagnosis, and conservative safety wording.

5.Alisma Plantago-Aquatica — Water Requirements
- Soil Preference — Thrives in rich, organic, well-drained loamy or muddy soils, ideally with a slightly acidic to neutral pH between 6.0 and 7.5.
- Water Requirements — Requires consistent moisture; best cultivated in shallow water (up to 30 cm deep) or consistently damp, marshy conditions, mimicking its natural habitat.
- Light Exposure — Prefers full sun to partial shade for optimal growth, flowering, and development of medicinal compounds.
- Temperature & Climate — Adaptable to temperate climates, tolerating a range of temperatures; hardy in USDA zones 4-9.
- Propagation — Primarily propagated by seed, which often requires a period of cold stratification, or by division of rhizomes in early spring.
- Maintenance — Minimal care is generally needed; removing spent flower stalks can prevent excessive self-seeding and encourage plant vigor.
- Pests & Diseases — Generally robust against common garden pests and diseases, though watch for aphids or fungal issues in overly stagnant or humid conditions.
