Nymphaea × laydekeri is an artificial waterlily hybrid of Nymphaea alba, Nymphaea tetragona,[1][2][3][4] and possibly Nymphaea mexicana,[5][2][3] which has been naturalised in Sweden[6] and the United Kingdom.[3]
Description
Vegetative characteristics
Nymphaea × laydekeri is an aquatic, perennial,[7] rhizomatous[8] herb[9] with branched or unbranched rhizomes.[10] Roots emerge from the rhizome at the leaf bases.[8] The small,[4] green,[11] circular,[2][5] 22 cm long, and 19 cm wide wide leaves[12] are mottled with brown colouration[2][5] but such colouration may be absent,[5] as the colour may fade to green as the leaf ages.[13][12]
Generative characteristics
The small,[4] fragrant,[14][15] diurnal,[7] pink or red[4] up to 10 cm wide flower[11] has a square receptacle with a recession around the peduncle.[4] The flower has 20 petals.[12] The stamens are yellow to orange.[16][5] It is sterile.[10][16][17] Flowering occurs from June to September.[3]
Taxonomy
It was described by Maurice de Vilmorin in 1891.[14][1][18] The taxon authority appears to be disputed. Some sources list Maurice de Vilmorin,[18][1] while others list Joseph Bory Latour-Marliac,[4][5] or Édouard-François André as the taxon author.[19][20] In the latter case, the name is published by André but attributed to previous work by Latour-Marliac.[19]
Etymology
The hybrid name laydekeri refers to Maurice Laydeker, the son in law of Joseph Bory Latour-Marliac.[21][13]
Hybridisation
It is a hybrid of Nymphaea alba, Nymphaea tetragona[1][4] and possibly Nymphaea mexicana.[5][2]
Distribution
It has been naturalised in Sweden[6] and the United Kindom.[3] In the UK, it has been widely introduced to old gravel pits, reservoirs, ornamental ponds, and lakes.[3]
Cultivation
It is cultivated in small ponds,[22] in very shallow,[17][23] or in deep water.[24] It is susceptible to Phytophthora rot.[25]
