No, that’s not a mistake in the name – there really are two “pilularis” there. Perhaps to indicate the dwarf variety? It’s a guess. We’ve actually had this plant in our yard for over 30 years and it’s still going strong. Gets a little leggy, so needs pruning. I don’t think ours is the dwarf plant, which are supposed to stay a little cleaner close to the ground. These bushes are pollinators, but they’re more toward the harsh side of things, such as predator wasps, native flies, and beetles. But the native butterflies also like it, and anyway, the wasps are important so I’m glad to feed them.
