There are ten different plants in Indiana called Loosestrife, which encompass three genera and two families. I haven’t been able to find out what Loosestrife means or why people were calling all of these different plants Loosestrife. It’s a bit confusing when trying to id a plant and you find Loosestrife scattered about the pages.
This Loosestrife is a native perennial that blooms late in the summer in moister spots. It’s quite striking and the flowers last for a long time … a very pleasant plant to come upon while batting away the mosquitoes and deer flies.
Notice that the flower petals are round, but have a tip at the end.
