Plant Shelf Depth?

aww but the bees love it! Best fall nectar flower we have.

So true. Which is why I keep planting it! But only in pots and even then I give it threatening looks every now and then!

lol I planted it in our back field along a fence. Smells great when you mow it down, when it spreads out into the grass.
