I only have the first and it is just starting to sprout, but I have had it fail to come back in the past. I decided to try again last year. Coreopsis snowberry may not be hardy here. Many sources list it as Zone 6. Lobelia typically overwinters a rosette at the base, so that may be a bad sign.

Melissa, I've tried Lobelia QV twice and talked with some sellers - it sounds like a tough go in MN.

My Eupatorium Chocolate is always very late in making an appearance. I have had it about 4 years and so far no sign of it yet this season. I'd give that one a little more time, I think.

I see no sign of any Eupatorium yet...and I have a prairie full.My persicaria "Fire Tails" is just now sprouting and it is 2 years old.

Good luck, Helen.

One of my Eupatorium Chocolate just starting showing new growth a couple days ago; the other one just today, so give it time to show.

I have one Persacaria (don't know variety) and it is just poking through too.

The other two are usually not too hardy in MN, but give them a few weeks. Not all plants are ahead of schedule like the weather has been, so if they're keeping to a normal weather schedule, there's still time for lots of different plants to still show up.
