I have many varieties of lungwort and never had a problem with them spreading and becoming invasive. They do not have rhizomes. They stay in a clump, and the clump slowly gets bigger over the years.

Mrs Moon seems to be the fastest growing and I have divided it many times to spread it around. The others are much slower growing and have never been divided. I have no experience with Victorian Brooch.

In my area lungwort cannot take direct summer sun. I tried. They do best under my weeping deciduous trees where they can be seeing flowering in the early spring, and then are protected from the harsh sunlight when the trees leaf out, which is just around the same time that the lungwort stops flowering. I do have a few mixed in with hosta on the north side of my house and they do fine without much sun.

Thanks Dilly_Dally! Do yours reseed at all? Or are pulmonaria sterile?

Mrs. Moon likes shade and moist soil. Yes, she does re-seed.
I find her 'children' all over the yard. I think you may be seeing photos of the lung wort in bloom and in early spring when it blooms it can have the appearance of a creeper. But after the blooms fade and the real leaves come out, then it takes on the mounding appearance of a hosta.

I have several different varieties of pulmonaria and I love them all. Some are in heavy shade under maples and some are in fairly sunny locations and they all seem to do well. Mine do re-seed also but not invasively. I like finding little baby plant here and there!

I'd love to see little seedlings (I have Mrs. Moon and Majeste), but it hasn't happened yet. I could put some new clumps to good use! My clumps just get bigger and bigger. They do well in both moist and dry (oak) shade.
I like to cut off the flowering scapes when the flowers are pretty much over (late May/early June in z4). It keeps the foliage from looking tatty. When a plant was new, this meant awfully few leaves were left when I was done pruning (ulp!), but it fills out nicely over the summer.

Hello,
I have lungwort in a shady region of my backyard. However, i wanted to plant impatients in that area instead. Is it bad for the plants to be moved this late in the summer or is it okay for me to move them somewhere else in the yard?

Perhaps, you've already moved them & figured out as long as you keep them moist they should re-establish themselves even in summer.

Another idea is to plant impatiens in post & move them to where you want the color spots to the side of lungwort.
