I was reading about sweet fern, and it says "Wind-pollinated shrub that doesn’t attract bees or butterflies, but it is an extremely popular host plant for a wide variety of caterpillars: geometer moths, miner moths, dagger moths, underwings, saturniid, hawk and sphinx moths. Horticultural source.".
What does this mean to someone who doesn't have much knowledge about plants? Do I want this in the middle of my garden, or a little ways away (i.e. 200 feet away in the middle of the butterfly garden)?
