WaterOrnamental oregano, including the 'Rosenkuppel' variety, should be watered when the top inch of soil feels dry to the touch. The frequency of watering will depend on the climate and growing conditions but typically ranges from once a week to every other week. When watering, apply water slowly and deeply to encourage strong root growth, using approximately 1 gallon of water per plant each time. During the hotter, drier months, you may need to water more frequently, while in cooler or rainy periods, less frequent watering is necessary. It's important to avoid overwatering and ensure good drainage to prevent root rot.
LightOrnamental oregano, such as 'Rosenkuppel', thrives in full sun to partial shade. The ideal spot for this plant is a location where it receives at least six hours of direct sunlight per day. However, in extremely hot climates, some afternoon shade can be beneficial to prevent scorching of the leaves. Avoid deep shade as it can lead to leggy growth and reduce the plant's vitality.
TemperatureOrnamental oregano, including the 'Rosenkuppel' variety, prefers a temperature range between 60°F and 80°F for optimal growth. It can survive minimum temperatures of around 30°F for short periods, making it suitable for growth in USDA hardiness zones 5 through 9. However, prolonged exposure to temperatures below freezing may damage or kill the plant. It's important to protect the plant from extreme cold and ensure it's in an environment within its ideal temperature range for the majority of the year.
PruningOrnamental oregano, like 'Rosenkuppel', should be pruned to maintain shape, encourage bushy growth, and improve air circulation. The best time for pruning is in early spring or after the plant has finished blooming. Cut back the spent flower stems and thin out any overcrowded areas. Doing this once a year or as needed will help keep the plant looking its best and encourage new growth.

Life cycleThe life cycle of Origanum 'Rosenkuppel', more commonly known as garden oregano, begins with seed germination, triggered by warm temperatures and moist soil conditions typically in the spring. The seedlings emerge, setting down roots and sprouting their first sets of true leaves. As the plant matures, it forms a clump of characteristic fragrant leaves on stems that may trail or spread, depending on the space provided. Throughout summer, garden oregano blooms, producing small, purple-pink flowers that attract bees and other pollinators. After flowering, the plant sets seeds, which can be dispersed by wind or wildlife, allowing for the natural propagation of the species. The plant is perennial, so it will enter a period of dormancy in the winter, with growth slowing or stopping, and then the cycle will resume with new growth from the root system in the following spring.
PropogationPropogation time
Late Spring-Early Summer
The most popular method of propagation for Origanum 'Rosenkuppel', commonly known as ornamental oregano, is through stem cuttings. Propagation is best done in late spring or early summer when the plant is actively growing. To propagate, select a healthy, non-flowering stem and cut a 3 to 5 inch (approximately 7.5 to 12.7 centimeters) piece. Strip the leaves from the lower half of the cutting and dip the cut end into rooting hormone. Plant the cutting in a pot filled with a well-draining soil mix, ensuring that at least two sets of leaf nodes are buried. Keep the soil moist but not soggy, and place the pot in a warm location with indirect light. Roots should develop within a few weeks, after which the new plant can eventually be transplanted outdoors.
