Care in one minute
Choose full sun in cool climates and give light afternoon shade where summers are hot and humid.
Plant in well drained soil with neutral to slightly alkaline pH.
Water regularly the first season; then water deeply but infrequently.
Feed lightly in spring only if soil is poor.
Shear spent stems after the first flush to promote rebloom.
Divide mature clumps every few years to keep plants vigorous.
Watch‑outs

- Not as drought tolerant as some Nepeta.
- High humidity can reduce vigor.
