A Mysterious Perennial Marigold
A few years ago I bought this variety of perennial marigold that keeps coming back every year and blooming wonderfully.
I can’t figure out the species, however.
The scent is musky and zippy and I was told this species is an excellent nematode repellent.
The leaves look similar to an annual marigold but this plant never gives up.
Any idea what it is?
