A couple of months ago the local plant club placed an order from Oriental Aquarium. One of the members had ordered C. x willisii. However, the plant he got was quite large – 7-8″ tall. He gave me one, asking me to try and flower it so that he’d be able to get an ID on it. I planted it in 100% ADA Amazonia. Today it flowered – here are the pictures.
Note the yellow throat, texture of the spathe and color inside the tube.
Confirmed – Cryptocoryne x Willisii
