Monster cashmire bouquet?

I planted it a couple years ago and now I keep finding new ones coming up. They all grow along the backside of the planter/against the house facing East. They seem to not be able to take too much sun.


Do their roots travel and have I created another monster that I need to control the growth of?

Monster cashmire bouquet?
Mass of foot high Cashmere Bouquet in mid-spring. Detail of flower buds. Arriving in Davis by way of its native China, this member of the mint family is frost-hardy and considered a deciduous shrub, though it doesn't display the expected round shrub form — it's more like a stick with leaves and a beautiful flower head, though pruning close to ground level will create a multi-stemmed shrub; deadhead this plant through the summer for a repeating floral display.





Take note that Cashmere Bouquet spreads by underground runners, which make it quite an invasive beauty as it pops up throughout your lawn. The runners can go as far as about 9 feet before resurfacing, but they are fairly thick and don't seem to travel too deeply underground; a 6" soil barrier may be sufficient to control growth.





The plant stem is semi-woody, possibly lending to its deer-resistant qualities; ants love this plant though! If you decide to cut some for your home, shake/spray off the ants that are very likely to be crawling throughout the flower cluster.
