Positive Todd_Boland On Nov 16, 2004, Todd_Boland from St. John's, NL (Zone 5b) wrote:

The subspecies montanum has narrower leaves than ssp. glaucum, with leaves that are plain green, not blue-tinted. The flower heads may be a little larger than glaucum. Self-seeds to a degree so may want to deadhead to keep it in check.
