Origin
Monardella lanceolata Gray var. glandulifera I.M. Johnston, commonly known as Sierra monardella, is a species of flowering plant in the mint family, Lamiaceae. It is native to California, specifically in the Sierra Nevada, and can be found in subalpine meadows, rocky slopes, and talus.
Common Names
The plant is commonly known as Sierra monardella, but other names include lanceleaf monardella, lanceleaf pennyroyal, and Sierra mint.
Uses
Sierra monardella has been traditionally used by Native Americans for medicinal purposes such as treating colds, coughs, and headaches. The plant has also been used for aromatherapy due to its strong, minty scent. However, it is not commonly used today and its effectiveness has not been scientifically proven.
General Appearance
Sierra monardella is a low-growing perennial plant that typically reaches 8-16 inches in height. It has lance-shaped leaves that grow to about 2 inches long and are covered in tiny hairs and glands that give off a minty scent when crushed. The plant produces small, pink to lavender flowers that bloom from summer to fall and attract bees and butterflies. The flowers develop into brown, nut-like fruits that contain seeds which are dispersed by the wind.
Light Requirements
Monardella lanceolata Gray var. glandulifera I.M. Johnston requires full sun exposure for optimal growth. It cannot tolerate shade and requires direct sunlight for at least six hours a day.
Temperature Requirements
This plant species grows in a variety of temperature zones but thrives best in Mediterranean-like climates. Temperature range of 60-80°F (15-27°C) is optimal for its growth. Frost and extreme heat can damage the plant.
Soil Requirements
Monardella lanceolata Gray var. glandulifera I.M. Johnston grows best in sandy, well-drained soils. A slightly acidic to neutral soil with a pH of 5.5 to 7.0 is ideal for its growth. The plant cannot tolerate clayey and poorly drained soils. It requires moderate soil moisture and adequate soil fertility.
Cultivation Methods
Monardella lanceolata Gray var. glandulifera I.M. Johnston is a relatively easy plant to cultivate. You should start by selecting a well-draining soil mix that is rich in organic matter. Plant the seedlings in a sunny location that receives at least six hours of direct sunlight each day. The ideal pH range for this plant is 6.5-7.5.
Watering Needs
Watering is an essential aspect of caring for Monardella lanceolata Gray var. glandulifera I.M. Johnston. During the growing season, you should water regularly, ensuring that the soil is constantly moist. However, do not overwater the plant, as this could lead to root rot. During the winter months, reduce watering frequency, allowing the top layer of soil to dry completely before watering.
Fertilization
Monardella lanceolata Gray var. glandulifera I.M. Johnston thrives in soils that are rich in nutrients. You can achieve this by applying a balanced, slow-release granular fertilizer during the growing season. Apply the fertilizer according to the manufacturer's instructions, taking care not to overfertilize the plant. Overfertilization can lead to excessive growth and weak stems.
Pruning
Pruning Monardella lanceolata Gray var. glandulifera I.M. Johnston is critical to its growth and development. You should prune the plant at least once a year, preferably in late winter or early spring before new growth begins. Trim back any dead or diseased stems to encourage healthy growth. You should also prune back any overly long stems to encourage bushier growth.
Propagation of Monardella Lanceolata Gray Var. Glandulifera I.M. Johnston
The Monardella lanceolata Gray var. glandulifera I.M. Johnston is a perennial shrub whose propagation can be done through a variety of methods. These methods include seed propagation, vegetative propagation, and stem cuttings.
Seed Propagation
Seed propagation is the most common method used to propagate Monardella lanceolata. The seeds require stratification before planting which involves sowing the seeds in a cold environment (below 5°C) for a period of 2-3 months. Once the stratification process is complete, the seeds are sown in a mixture of coarse sand and peat or in a light potting soil. Germination is expected to occur within 1-2 weeks.
Vegetative Propagation
Vegetative propagation of Monardella Lanceolata Gray var. Glandulifera I.M. Johnston can be done through root division, layering or through suckering. Root division involves uprooting the plant and dividing the root mass into several sections. These sections can then be replanted into separate pots. Layering, on the other hand, involves encouraging roots to grow from a stem while it is still attached to the parent plant. Once the roots start to form, the stem can be cut and planted in a separate pot. Suckering involves allowing the plant to produce shoots close to the base of the main stem. These suckers can then be separated from the parent plant and re-potted.
Stem Cuttings
Stem cuttings involve taking cuttings of stems that are approximately 4-6 inches long with a few leaves attached. These cuttings can be dipped in rooting hormone and planted in a mixture of peat moss and sand. The cuttings should be kept moist and in a shaded area for 2-3 weeks. The roots should start to develop after this period, and the new plants can be transplanted to bigger pots.
Disease and Pest Management for Monardella lanceolata Gray var. glandulifera I.M. Johnston
While Monardella lanceolata Gray var. glandulifera I.M. Johnston is generally a hardy plant, it is not immune to disease and pests. Below are some common issues that may arise and suggested management techniques.
Diseases
Phytophthora Root Rot: This disease is caused by a soil-borne fungus and can cause wilting, yellowing and eventual death of the plant. To manage this issue, avoid overwatering the plant, ensure proper drainage, and consider adjusting the planting location to an area with improved drainage. Remove any infected plants and soil to prevent further spread.
Powdery Mildew: This fungal disease may appear as a white or gray powdery substance on the leaves and flowers. Remove any infected portions of the plant and consider treating with a fungicide for more severe cases.
Bacterial Leaf Spot: This disease causes brown spots with yellow halos to appear on the foliage. Remove any infected portions of the plant and avoid overhead watering. Consider treating with a copper-based fungicide.
Pests
Spider Mites: These tiny pests may cause stippling or yellowing of the leaves, as well as fine webbing on the plant. To manage spider mites, use a strong jet of water to knock them off the plant or consider using an insecticidal soap or oil.
Aphids: These small insects can cause curling of the leaves and yellowing of the plant. To manage aphids, use a strong jet of water or insecticidal soap to remove them from the plant.
Thrips: These insects may cause distorted growth and discoloration of the plant. Consider using a systemic insecticide or releasing beneficial insects, such as ladybugs or lacewings.
By being vigilant and promptly addressing any disease or pest issues, you can help keep your Monardella lanceolata Gray var. glandulifera I.M. Johnston plant healthy and thriving.
