All summer, I’ve been enjoying the highly incised silvery-green foliage of the mums I don’t remember planting, which grew to three feet tall because I didn’t remember to pinch back what I didn’t remember planting. But instead of producing flowers in September as I expected, they are behaving more like a grass, generating fronds with small seed pods. None of my books is any help whatsoever in explaining this phenomenon.
Is this what happens when you try to perennialize these plants? Are they unhappy about my cold winter and this year’s cool summer? Or are they unhappy about not being composted last April?
