Phlomis tuberosa
A tuberous-rooted perennial with flowers appearing in well-spaced whorls stacked vertically along sturdy stems. The stalks pierce through the flower centers in the characteristic manner of this genus. Thick, tuber-like roots form a dense, non-spreading crown that increases slowly over time.
Adaptable to any regular garden soil and notably reliable in performance. Native to dry meadows and rocky hillsides from central and southeastern Europe extending into northern Iran and Siberia. The stalks remain structurally sound deep into fall and can be used for dried arrangements. Great Plant Pick selection.
