Thanks for your help.
Here's a perennial plant - leaves have an herby fragrance when rubbed between fingers. No sign of blooming of any type so far this year as of June 12. Stands about 2.5 to 3 feet tall and equal spread- seems pretty vigorous. Stems are squarish, but leaves are alternate. Any ideas?? (Nevermind the malva sylvestris coming up in the middle of the mystery plant.) Thanks!!
Jane, can you give any background on yours? How about a leaf/foliage picture?
iborla, you should start a new thread.
