[MAIPC] Looking for info on Centaurea depressa - low cornflower, Indian knapweed

[Koop, Anthony L - APHIS]

Hi all,

I am currently doing a weed evaluation on Centarua depressa. USDA-GRIN says it is naturalized in Nevada and Maryland, and BONAP has both of those states in blue. The Flora of North America reports it is introduced in these two states; noting that FNA did not use the word "established" I am guessing that this species is probably casual in the U.S. The Maryland Plant Atlas reports it as a waif for the state.

I wanted to see if anyone has seen it.

Thank you,

Tony
