Dear List, Here is the plant info on Shinnersia rivularis from a plant source I've used, AquaSpot World: Name: Shinnersia rivularis (Mexican Oak Leaf) Genus: Shinnersia Family: Asteraceae Structure: Stem Origin: Mexico Height: 40-60 cm Width: 10-20 cm Light: Medium - Very High Temperature: 20-28 degrees C. pH: 5.5 - 9.0 Growth: Fast Difficulty: Easy The retailer states, "Shinnersia rivularis is native to Mexico and is commonly known as the 'Mexican Oak Leaf,' due to its resemblance to oak foliage. It is an extremely fast growing stem plant and makes little demands in the aquarium. Strong lights should be used to speed up growth." I'd ordered a variegated form of it, although unfortunately it did not survive the shipping.
