Oregano
Origanum vulgare
Origanum vulgare, commonly known as Oregano, is a resilient perennial herb celebrated for its pungent, aromatic leaves that are a staple in Mediterranean and Mexican cuisines. This plant forms a woody-based shrub with small, round, fuzzy green leaves and produces delicate clusters of pink or purple flowers during the summer months. Beyond its culinary appeal, it serves as an attractive groundcover or container plant that attracts pollinators like bees and butterflies.

Pet Warning
Oregano contains phenols and terpenoids which can cause gastrointestinal upset, including vomiting and diarrhea, in dogs and cats if ingested in large quantities. The essential oil is significantly more toxic than the fresh plant.
Care Guide
Oregano Care Guide
Light and Location Place your Oregano in a spot that receives at least 6 to 8 hours of direct sunlight daily. A south-facing windowsill is ideal for indoor growth.
Watering Oregano is drought-tolerant once established. Water only when the top inch of soil feels completely dry to the touch. Avoid overwatering, as this plant is highly susceptible to root rot in soggy conditions.
Soil and Drainage Use a well-draining potting mix, ideally one amended with sand or perlite to improve aeration. A neutral to slightly alkaline pH is preferred.
Pruning and Harvesting Regularly pinch back the stems to encourage bushier growth and prevent the plant from becoming leggy. For the best culinary flavor, harvest leaves just before the plant begins to flower.
Seasonal Care If grown outdoors, Oregano is hardy but may benefit from mulching in cold climates. Indoor plants should be kept away from cold drafts or dry heating vents during the winter months.
