Growing Oregano
Plant Oregano in a sunny, well-drained spot. For container-grown plants, water when the top 1" of soil is dry. The pungent leaves are delicious both fresh and dried. Greek Oregano (Origanum vulgare hirtum) needs little care beyond cutting down the stems during fall cleanup. Hardy in Zones 5-9.
Ornamental Oregano
Ornamental varieties are valued for their handsome flowers and foliage rather than for culinary use. The showy, aromatic flowers bloom from summer to fall. Plant in full sun in average well-drained soil amended with grit or sand to ensure good drainage. This is particularly important during cold weather, when plants are dormant. Prune back winterkilled stems in spring.
Growing Ornamental Oregano Indoors
Plants need full sun (6-8 hours a day)—a south window generally works well. Cool temperatures, 60-65°F, are best. Water plants only when top 1" of soil has dried out. Fertilize monthly, April-August only.
