I've grown it for years and mine have never spread that much. Every few years the current parent dies out, but by then a new one has sprouted to continue the cycle. I usually am very religious about deadheading though.
I do cut it back by two thirds after flowering and normally I get a second, smaller flush late in the season.
Tasymo, I don't think I have mulberry tree. I am bad with names of trees, but I did some search and it doesn't look like I have mulberry.
I have I think are oak trees. The ones whose seeds have wings and land all over the place. I think these seedlings might be those. They look familiar to me before I even grew coneflower, so I didn't think they were coneflower but since I have planted some coneflowers, I thought I should better check before I pull them out so that I won't accidentally kill what I intend to keep. :)
Interesting, for me, especially re (factors affecting) garden lupin longevity.
I don't use lupins now, in mixed perennial beds, for the reason that they are so short lived; my experience is that the plants (purchased in flower) never last more than a year or two in our growing conditions.
All (or most?) of the available garden lupins are derived from the Russell strain. The latter, based on wild Lupinus polyphyllus, are nevertheless of extremely hybrid origin. As such it makes sense that the Russell strain needs to be maintained by active breeding. After a hiatus of perhaps 10/20 years, active breeding and reselection of the Russell strain resumed at the Woodfield Nursery, Stratford-on-Avon, UK in 1970 and the "New Generation" lupin is the result.
I've read that "New Generation" lupins last 7 or 8 years. Can anyone corroborate that?
Ives, re your seeds, I would make sure they are all dry and darkened, then strip them off the plant and toss half of them onto the ground where you might like to have more growing and save the rest for planting later or trading for other seeds you might decide you'd like. They do wintersow very well for me.

I have moved perennials in the middle of blazing hot summer many times and they almost always do okay although some may sulk a little before rebounding. From my perspective, living in a very very hot summer climate, I would think any plant would come through a move with only 75-79 degree temperatures on the 1st of July! I could only dream of such a thing... (But, of course, I suppose there's never a guarantee that a plant won't die after transplanting any time.)
Nhbabs....as soon as the weather round here decided whether its gonna snow, rain, or be 70*, I sure will plant 'em....lol. Damdest weather I've ever seen.
Ken....loved ur story. Now I'm not so sure if I want to 'let 'em outta their cage'...lol!! Coincidentaly, QVC was airing their Spring Fling gardening show last nite, which included a flat of sedum varieties and the guy was describing them pretty much like u did. He walks, drives, etc. on it. can't kill it! LOL
I don't think that L. spicata is either bulbs or corms. My memory of planting hundreds is that it's simply rhizomes.
I remember it as the kind of corm that technically isn't a bulb, but looks like one.
