Great perennial!
"Pretty amazing plants. As another poster said, they don't flower much in 1st year. This second year, now it's early summer and they've gone bonkers! I actually didn't just spread them on surface of soil but sunk the seeds down and inch or two and many still sprouted and grew. In the future I'll try just spreading or lightly sinking as noted. Not sure if there's even any leaves bit by bugs - they all look so healthy. Very pleased. They don't look like much in the winter but DID maintain green leaves all through our winter (zone 5, -25 deg F last winter & lots of snow)."
