I am currently using this plant in outdoor planters and since it is doing so well, I am going to use it between paver blocks in a part of my garden that needs some filler. The silver grey color will go well with the pavers.

This is a pretty plant that grew well in my herb garden this year. I too had voracious caterpillars that turned into (I forget what, something pretty) and then the plant grew back with no problem. I did, however, originally believe it to be an herbal/edible, and since it is poisonous I will not be replanting it. Also, I am grateful that it is an annual/tender perennial, as it grew very quickly and would have probably taken over that half of my herb garden.
I plant for nature as well as myself. This plant was covered with caterpillars which consumed my plants. I was surprised to have the plants rebound in a few weeks healthy and robust. The larvae turned out to be Painted Lady butterflies.

This plant makes a wonderful foliage accent in containers. It is extra-easy to propagate. As unwanted growth is pinched off to maintain the plant's shape, it can be inserted into a pot where it will root without any special care. Since flowering is insignificant, plants should have buds pinched off as they form, making the plant even bushier.
