Oregano Origanum laevigatum
ABOUT
Origanum laevigatum, commonly known as the ornamental oregano, is a perennial herb that is valued for its aromatic foliage and charming flowers. The plant typically sports a bushy growth habit, with branching stems that hold small, oval-shaped leaves. These leaves are often a gray-green hue and may have a slightly fuzzy texture, befitting many plants in the mint family, to which ornamental oregano belongs. The most striking feature of the ornamental oregano is its blooms. In the peak flowering season, clusters of tiny, tubular flowers appear, giving the impression of a cloud of color. These blossoms can range in hue from soft pinks to deep purples, sometimes with a hint of lavender, and are adept at attracting pollinators such as bees and butterflies. The flowers typically form in loosely arranged, terminal racemes, which create a delightful visual contrast against the backdrop of the foliage. Adding to the allure, the plant's stems can take on a reddish or purple tinge, which further enhances the overall presentation. This herb is often praised for its resilience and ease of growth, making it a popular choice in gardens where a splash of color and an inviting, aromatic atmosphere are desired.

WaterThe Origanum laevigatum, commonly known as the Hopley's Purple oregano, prefers moderate watering, allowing the top inch of soil to dry out between waterings. In general, watering once a week with around 1 gallon per plant should suffice, depending on the climate and soil drainage. Overwatering can lead to root rot, so it's important to ensure the plant has well-draining soil. During the summer months, you may need to water more frequently to keep the soil consistently moist but not waterlogged. In winter, reduce watering as the plant's growth slows down.
LightHopley's Purple oregano thrives in full sun, receiving at least 6 to 8 hours of direct sunlight a day. The best spot for this plant would be in an area where it can enjoy unobstructed sunlight, such as a south-facing garden bed or a sunny windowsill if grown indoors. However, in extremely hot climates, some afternoon shade can help prevent scorching.
TemperatureHopley's Purple oregano does well in a range of temperatures but prefers a temperate climate. The ideal temperature range for this plant is between 60°F and 80°F. It can tolerate temperatures down to about 30°F, but it should be protected from frost. The plant will struggle in temperatures exceeding 90°F and may require some shade and extra water in these conditions.
PruningHopley's Purple oregano should be pruned to promote bushy growth and to prevent it from becoming leggy. The best time to prune is in the spring as new growth starts to appear. Remove around one-third of the plant's height, cutting just above a set of leaves to encourage branching. Regular trimming of the tips throughout the growing season can also encourage a denser form.
CleaningAs needed
SoilThe best soil mix for the plant commonly known as Hopley's Purple Oregano should be well-draining with a loamy to sandy composition. This mix can be achieved by combining two parts potting soil, one part coarse sand, and one part compost to ensure nutrient-richness and good drainage. The soil pH should ideally be within the neutral to slightly alkaline range, around 6.5 to 8.0.
RepottingHopley's Purple Oregano typically does not require frequent repotting. It should be repotted every two to three years, or when the plant outgrows its current container, to ensure the root system has sufficient space and the soil remains fertile and well-draining.
Humidity & MistingHopley's Purple Oregano prefers low to average humidity levels. As a Mediterranean herb, it is accustomed to drier climates, so the best humidity level for this plant would be between 30% to 50%. It is important to avoid overly humid environments which can lead to issues such as fungal infections.
Suitable locationsIndoor
Place in a sunny spot with well-draining soil and minimal watering.

Life cycleOriganum laevigatum, commonly known as hop marjoram, begins its life cycle as a seed, which after dispersal will germinate in favorable conditions of warm temperatures and moist soil. The seedling emerges and develops into a vegetative plant, forming a rosette of leaves as it matures. The plant experiences vegetative growth, producing strong stems and aromatic leaves characteristic to this herbaceous perennial. Once mature, hop marjoram produces small, purple flowers typically during the summer, which are attractive to bees and other pollinators. After pollination, these flowers develop into seed heads that release new seeds to complete the reproductive cycle. Throughout its life, hop marjoram enters a period of dormancy in the colder months, only to resume growth in the spring.
PropogationPropogation time
Spring to early summer
Propogation: The most popular method to propagate Origanum laevigatum, commonly known as 'Hopley's Purple' oregano, is through stem cuttings. This typically takes place in late spring or early summer when the plant's growth is most vigorous. You start by selecting a healthy, non-flowering stem and cutting a 4- to 6-inch (approximately 10 to 15 centimeters) portion from the parent plant. Strip the leaves from the bottom half of the cutting, and dip the cut end into a rooting hormone to encourage root growth. Then, plant the cutting in a well-draining soil mix, ensuring at least two sets of leaf nodes are buried where roots can develop. Keep the soil consistently moist but not soggy and place the pot in a warm, bright spot out of direct sunlight. Roots typically establish within a few weeks, after which the new plant can be gradually acclimatized to outdoor conditions if being moved from indoors.
