Italian Heather in Cold Climates: Container Growing for Zone 3b Gardens

Italian Heather (Erica x darleyensis) in Calgary

Not frost-tolerant; will not survive zone 3b winters outdoors.

Container Strategy

• Keep in pot year-round.
• Summer: outdoors in full sun.
• Winter: cool (40–45°F), bright indoor spot (east/south window).
• Soil: acidic; fertilize with Miracid.
• Water: keep barely moist in winter; regular in summer.

This gives seasonal color without winter loss.
