: Nelumbium speciosum, Nelumbo speciosa, Nelumbium nelumbo
: Asian lotus, Indian lotus
: Introduced to North America as a water garden plant.
: Perennial, emergent aquatic plant that produces individual flowers and leaves directly from the root system.
: Float on the surface of the water or are held up to 6 ft above the water by their petioles; circular peltate blades, 0.75-2.5 ft across, medium green or blue-green in color, hairless; margins are smooth, often undulating up and down, leaves that are above water are depressed toward the middle; many veins radiate from the center and become forked.
: Light green in color, terete, hairless, smooth or somewhat prickly, contains hollow chambers that keep stems (petiole) erect and convey oxygen to the root system.
: Held up 6 ft above the water surface by peduncles (flowering stalks), 4-8 in across, consisting of about 15 pink tepals, a golden yellow receptacle, and a dense ring of golden yellow stamens; receptacle is located in the center of the flower, cone shaped, and has 15-35 short styles that look like small bumps; blooms during the summer and lasts for 2-3 months; short lived opening during the day and loosing their petals by afternoon; fragrant.
Fruit and seeds
: Each flower is replaced by a seedpod spanning 3-4 in across and 0.75 in deep; becomes dark brown with maturity; individual seeds are exposed in small chambers; seedpods bend downward to release seeds.
: Native to Asia (Iran to Japan) and northern Australia; grows well in 6' deep, mucky submerged soil and a sheltered location with little exposure to wind and waves.
: Vegetatively by its thick rhizomes and fibrous root system; also by seeds.
: American lotus (Nelumbo lutea
), which can be distinguished from Sacred lotus by their yellow flowers.
Monitoring and rapid response
: Very small populations can be controlled by hand-pulling. Physical removal should be completed before flowering and seed set. Aquatic approved herbicides may control populations. Application of aquatic herbicide requires permit.
