Just sort of interesting...

Sorry, no, I don't know what it is, and haven't found anything similar by googling.  Did it have yellow or white flowers?  Sounds spectacular!

The flowers were like oxeye daisy but the leaves are similar to your Tanacetum tibeticum.

Lori,
I need advice on what to do with Ajuga lupulina seed. I just received my Holubec order, and I may have additional questions as I work through them, but this one is special, as you already must know. Thanks in advance.

[Lori S.]

Hi, Peter,
I started seeds of Ajuga lupulina on Feb. 26/10 at 20 deg C and got germination on March 8/10.  The germination rate was low - my records aren't detailed enough to give details, but if I recall right, I only got a couple of sprouts, and I ended up with only one plant.  The seeds were collected in 2008.  So, it was encouraging to see quick germination (in 10 days) but maybe germination would have been better with conditioning/stratification.
I'll have to check if I have seeds left (I didn't collect any this year from it), as it would be a good idea to have a backup plant! 
Unlike some of the other plants I showed in this thread, it remained fairly large as it developed, with the flower stalks reaching about 8" tall.  I did post photos of the second-year plant in bloom elsewhere, but in case you missed it, here it is:

Those are pretty drastic changes.  A helpful FYI for the novice alpine seed grower, too.

I might add that such changes occur while still in the pot, too, from inside conditions to outside climates.  These are Corydalis wilsonii grown from seed started this past winter.  The last of the original "inside grown" leaves is turning, while the rest hang dried around the pots (cups).  Leaves are quite thick, and there was a significant amount of shrinking as they dry.

The second pic was take while still growing inside the house.  I'm not sure which growth pattern I like better...

I hope they survive my Minnesota winter.

Cool Corydalis, Rick... at first glance, quite similar to the local C aurea, but the leaves are bluer close up, really nice form...

Leucanthemum vulgare is a very variable species, at least in Norway, and it grows almost everywhere.
Several forms are common along roads etc. These are often taller and coarser than those found in meadows etc.
At our cabin in the mountains grows a smaller, more refined form that spread by creeping rhizomes. We also have two other forms that are taller and not spreading in the same way.

To the left: The smaller form, to the right: The bigger form. It is easier to see the differences when you see both at the same time!

Is it native to Norway or introduced?  I often find it difficult to find out the natural ranges of European plants.  (I did see that it is native to the UK.)  That one is pretty but, unfortunately, is a very invasive and widespread plant in North America.

I agree Lori, the oxeye Leucanthemum vulgare (syn. Chrysanthemum vulgare) is an in an introduced weed throughout North America; I'm always ripping this plant out.  It is listed on a number of State noxious weed lists, and generally considered an undesirable invasive.

It is native here but some forms are probably introduced. And although it is invasive in disturbed areas it is in fact declining in some places, notably pastures. Some forms are rather shortlived but others (like the left shown above) are almost perpetual

I have only seen one form of this invasive here in Minnesota.  But I suppose that would be the norm: being variable in its place of origin, and not so much where it has been introduced.  It is fairly widespread throughout the state, but really only common in the northern half, at least from what I have seen.

Trond: I would be interested in getting hold of your different forms of Leucanthemum vulgare next time you're up here  

[Hoy]

It's  a bit difficult, Stephen. Next time is  - vinterferie! But when the snow thaws

[stephenb]

I can probably wait that long
