Eichhornia consists of perennial plants that grow from rhizomes, thriving in marginal to deep-water environments. The submerged foliage is typically linear or strap-like, while the floating and aerial leaves are either rounded or heart-shaped. In summer, these plants produce prominent, funnel-shaped blooms that are arranged in upright spikes.
