This variety is short mounding plants when grown in bright shade to full sun. In shade, bit taller and broader leaves.

I have them growing in beds around trees and bushes - nice ground cover if that is what you need/want.

Once established - will tolerate drought - evergreen in Tomball, TX (northwest of Houston, TX).

Have some growing in containers - doing very nicely -

I too was awed by the fantastic show of purple flowers...then the second year came around and before I actually realized it, the plant doubled in size and started sending up shoots 1-2 feet away. I tried to keep it in check but it became a constant battle. I just came in from digging a hole about 5 foot around and 18 inches deep. This was how big the root structure got in 2 years...from now on, if I want to have another one, it will forever remain in a planter.

I must second the evil/invasive comment below. This plant is escaping and becoming established and problematic in the Houston area. It's gorgeous, but we really don't need another exotic weed in Texas.

I once had a thriving fern garden on the shady side of the house. I added a four Mexican Petunias to add a few flowers. They were located off to a corner. Two years later---I had a full, thriving garden of these and only a few ferns. Be careful where you plant this harmless little plant. It is evil and subtle. SAN ANTONIO, TX
