01 · Light & site

Give it the light its growth depends on.

Full to part sun, with roughly 4 to 7 hours of useful light. Perennial timing and winter survival are region-specific

02 · Water & soil

Keep roots supplied without trapping water.

Water the complete root zone, then recheck conditions before watering again.

Soil
Loose, moderately fertile garden soil
Drainage
Well drained
pH
Species-dependent, commonly mildly acidic to neutral

03 · Spacing & roots

Make room for the mature plant.

Space plants about 18 inches apart. Expect a mature plant around 24 inches tall by 24 inches wide.

Spreading roots or runners can extend beyond the visible crown.

04 · Start

Begin with the method that protects establishment.

Use a healthy transplant, division, slip, or crown suited to the species.

05 · Care

Support healthy growth through the season.

Usually self-supporting at the stated mature size. Add a discreet stake only if wind, bloom weight, or an exposed site makes it necessary.

Flowering and wildlife value

60 to 90 days. Grow it for botanical interest and keep it clearly labeled. Historical or cultural use does not establish safe ingestion or medical benefit.

07 · Safety

Know the cautions before you place or use it.

  • Can spread by seed and clump expansion; deadhead or contain where needed.
  • Confirm personal food and medication considerations before concentrated herbal use.
