Hi,
It's actually spelled 'Windelov'. I ordered one from Arizona Aquatic
gardens. I received an approx. three-inch length rhizome with a few large
leaves (emerse I believe). It took off well and seems to grow as fast or
faster than my regular type JF's. It's exciting watching it's new leaves
grow out- it's a neat plant.
Best Wishes,
Zach K
