Light & Site Requirements

• Best in part shade (i.e., morning sun + afternoon shade) for optimal foliage colour, especially in regions with strong sun. According to the manufacturer, sun or shade is acceptable.

• In cooler climates (such as Zone3), this cultivar may tolerate more sun so long as the soil remains welldrained and moisture is adequate.

• Soil: Preferably humusrich and welldrained to avoid crown/root issues. Avoid sites where water stands.

Watering & Maintenance

• At planting: Keep soil evenly moist until the plant establishes.

• After establishment: Moderate watering; the foliage is evergreen/semievergreen and will benefit from consistent moisture but not soggy conditions.

• Mulch lightly in early spring (especially in colder climates) to moderate soil temperature.

• Pruning/cleanup: In early spring, trim back any tattered foliage to allow new growth. Remove spent flower stalks if desired.

• Fertilizing: Apply a light topdress of compost or slow release fertilizer in spring; avoid heavy feeding which may encourage floppy growth.

ColdClimate / Zone3 Considerations

• Although explicitly rated to Zone4a, in a favorable sitefull sun or bright part shade, excellent drainage, sheltered from harsh drying windsthis cultivar can succeed in Zone3.

• Ensure site does not have water pooling or heavy clay that remains saturated during snow meltHeucheras are susceptible to crown rot or heaving in freeze/thaw cycles.

• Because its foliage is the main feature, winter appearance matters: choose a site with some snow protection or wind buffer if possible.

• Early spring: inspect for crown lift/heaving; reseat plant and remulch if necessary.
