Hmm...well, you may have hot and sticky weather, but bet it's worse
here and they seed around like mad. Now, what kind of soil do you
have? Are you too neat a gardener or is your mulch too thick?
I am so jealous of your var. brunnera. One of these days I will
gather courage and try this, tho' it is supposed to loathe and
despise hot climates.

I don't know. It's either that or that the gravel and stone keep the
soil moist for them. But my gravel drive is the world's seedbed.

Don't lose hope. It is supposedly rampant in Iowa. Keep an eye out
for the seedlings, they are marked exactly like the adult leaves.

Could happen, but won't until end of this month, I think. They are
late germinating, waiting for the soil to really warm up. You might
even find last year's plants returning. They make a huge tap root
and will overwinter if it is mild and they are mulched or have
sufficient leaf fall left on them.

Yes, they were hard to scan clearly. And, it was late in the season
(May) so they were going to seed and I couldn't find any of them in
flower at the time. No, I'd take chickweed. Hate bittercress, it is
nearly impossible to eradicate, but diligent pulling of chickweed
while it's small will get rid of it - have found you have to get the
root or it will return and it wants to break off just above the soil
line when you pull it. I'm down to only a couple of places where it
returns regularly. Will never get rid of the bitter cress, poa
annua, garlic mustard or pokeweed, I fear.
