Introduction 

Water hyacinth (Eichhornia crassipes) is a free-floating perennial aquatic plant native to tropical and subtropical South America (Mahmood et al., 2005). It features broad, thick, glossy, ovate leaves that can rise up to 1 m above the water surface, supported by buoyant bulb-like nodules at the base of its stems (Khotsa et al., 2025). The plant has long, spongy stalks and feathery, purple-black roots, while its flowers are arranged on erect spikes, typically lavender to pink with six petals (UF/IFAS Center for Aquatic and Invasive Plants, n.d.). Outside of its flowering period, water hyacinth may be confused with other floating plants, such as frogbit (Limnobium spongia) or Amazon frogbit (Limnobium laevigatum).

Water hyacinth is among the fastest-growing plants, reproducing primarily via stolons and producing thousands of seeds annually, which can remain viable for over 28 years (Sullivan & Wood, 2012). Under ideal conditions, mats of water hyacinth can double in size in one to two weeks, and plant counts may increase more than a hundredfold in 23 days (Dickinson & Royer, 2014). In its native range, pollination is primarily by long-tongued bees (Coetzee et al., 2017). The species reproduces both sexually and clonally, with large patches often representing a single genetic form (Harun et al., 2021).Water hyacinth exhibits tristylous flowers with three morphs based on pistil length: long (L), medium (M), and short (S) (Rojas-Sandoval & Acevedo-Rodríguez, 2013). Tristylous populations are restricted to its native South American lowlands, while introduced populations predominantly feature the M-morph, with occasional L-morphs and absence of S-morphs (Barrett, 1977, 1989). This pattern suggests that founder events significantly influenced the species’ global distribution.
