Growing notes
- Outstanding bee forage over an exceptionally long season — May through September
- Drought tolerant and tough — thrives on poor soil
- Distinct from true catnip (N. cataria) — N. × faassenii is more ornamental, longer flowering, and far less attractive to cats
- Cut back hard after the first flush for a full second flowering
