While this isn’t something I can grow in my yard it is such an unusual plant I had to find out what it was and research it.
These lotus ( Nelumbo lutea ) are common at Brazo’s Bend Park every summer. I always feel as if I’ve wandered into the land of the lost when I see them. Notice the unusual center? This distinctive flat topped seed holder is what tells you it is not a water lily.
They grow in water as deep as 8′ and the stems each have a single round leaf up to 2′ in diameter. The flowers are about 10″ across and the largest of all flowers in North America.
