Sacred Lotus
(Nelumbo nucifera)

A very showy perennial aquatic plant that is native to the warmer regions of Asia. It is considered invasive due to the large and dense colonies it can produce if released into natural areas from cultivation.



Overview

Regulated areas of Sacred Lotus
This species is Prohibited (Red counties)

Other names for this plant include:

  • Common names: Asian lotus, Indian lotus
  • Scientific names: Nelumbium speciosum, Nelumbo speciosa, Nelumbium nelumbo

Ecological threat:

  • Dense mats of floating vegetation can inhibit other native aquatic vegetation, decreasing biodiversity.
  • Can affect other wildlife by blocking access to the water and/or reducing plants the animals depend on for shelter and nesting.
  • The dense floating mats of vegetation can negatively affect boating, angling and swimming.

Classification in Wisconsin: Prohibited

Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for sacred lotus was based upon this literature review developed by the department.

Identification

Leaves: Medium to blue-green leaves float or are held above the water. They are hairless with smooth edges that may undulate up and down. Leaves are large and showy, 0.5 to 3 feet across with many radiating veins.

Flowers: Very showy flowers are held up to 6 feet above the water. They have 12-15 pink petals with showy yellow stamens around a central large receptacle. Flowers are 4-8 inches across.

Fruits & seeds: After the short-lived flower blooms, the central seedpod remains. It turns from green to brown in color and these are often used in dried floral arrangements. Individual seeds form in the pod and may remain viable for extremely long times.

Roots: Thick rhizomes with fibrous roots - this plant can reproduce by rhizome as well as seed.

Similar species: Very similar to American lotus (Nelumbo lutea) it can be distinguished by flower color; American lotus has yellow flowers. Cultivars may have color variation, usually pale pink.

Distribution

Control

Mechanical: Very small populations can be controlled by pulling. Physical removal should be completed before flowering and seed set.

Chemical: Aquatic approved herbicides may control populations. Application of aquatic herbicide will require a permit.
