Stem: Creeping stem, 30-50 cm long, highly branched, with roots at the nodes.

Yi: Clusters of leaves, ovate to reniform in shape, 5-12 cm in length, 5-14 cm in width, rounded at the apex, heart-shaped at the base, entire, smooth, with distinct leaf veins; petiole 10-30 cm long, swelling below the middle to form a spongy air bladder.

Water hyacinth growth environment:

Temperature: Prefers warmth, intolerant of cold, optimal growth temperature is 25-30°C.

Lighting: Prefers full sun for optimal growth.

Moisture: Requires ample water, intolerant to drought, and grows best in water depths of 20-30 cm.

Water Hyacinth's Ecological Uses:

Water Purification: Water hyacinth can absorb nutrients like nitrogen and phosphorus from the water, reducing eutrophication levels in water bodies and serving as a water quality purification agent.

Eco-regulation: Water hyacinth absorbs carbon dioxide and releases oxygen during its growth, enhancing the dissolved oxygen level in water bodies. This plays a role in maintaining the balance of aquatic ecosystems.

Feed: Water hyacinth is rich in nutrients and can be used as feed for aquatic animals such as fish and ducks.

The ornamental value of water lilies:

Landscaping Creation: Water Hyacinth boasts unique shapes and colors, serving as an ornamental plant for water features.
