Thanks. Since I've killed it before, I'll post back in the spring if I need more. Was thinking of putting it in a shady place... I'll look for a sunnier spot.

To answer your actual question--it will takes a year or two to get a deeply established carpet of it. The roots are shallow and you need alkaline soil (lots of lime) and plant it in a place that gets 6+ hours of sun to get it established as quickly as possible. It is not a 'weed' in the sense that it will propagate anywhere under any conditions. Shade and high PH will kill it.

It can live in the frozen tundra.

It should survive but if, for some reason, it doesn't, post back in the spring and I'll be glad to give you lots - free!

Yes it is a tough plant to kill.

It's basically a weed people like. Yes. Most likely it will survive.

If I transplant some lambs ear now, will it survive the winter?
