It is native to North America, specifically found in the eastern United States from New York to Florida and west to Texas. The plant is commonly known as Hoary Mountainmint or Southern Mountainmint.
General Appearance
Hoary Mountainmint is a bushy plant that typically reaches heights of 1 to 3 feet. It has a square stem that is covered in tiny hairs giving it a white appearance. The leaves are opposite and oblong with toothed margins, and the undersides are covered in small hairs that create a silvery hue. The plant produces clusters of small white to pale pink flowers that bloom from June to September. These flowers are attractive to bees, butterflies, and other pollinators, making it an excellent addition to any garden or landscape.
Uses
Pycnanthemum incanum var. puberulum has several uses, both medicinal and culinary. The leaves of the plant contain essential oils that have been shown to have anti-inflammatory and antiseptic properties, making it useful as a topical treatment for skin irritations and bug bites. The leaves and flowers can also be made into a tea that has a minty flavor and is believed to have digestive and respiratory benefits. Additionally, the plant can be used as a natural insect repellent, with the essential oils in the leaves repelling mosquitos and other biting insects.
Light Requirements
Pycnanthemum incanum var. puberulum grows best in full sun to partial shade. It can tolerate shade, but its growth will be stunted and it may become leggy as it tries to reach for more sunlight. It is important to note that the amount of light this plant receives can affect the intensity of its scent.
Temperature Requirements
This plant is native to North America and can tolerate a range of temperatures. It prefers mild to warm temperatures and can withstand drought and heat. It can also survive in cold weather and is a hardy plant, able to withstand freezing temperatures in the winter. During the summer, it should be watered regularly to prevent dehydration.
Soil Requirements
Pycnanthemum incanum var. puberulum thrives in well-draining soils with good fertility. It can grow in a variety of soils, including sand and clay, but it prefers moist soils with adequate drainage. It is important to note that this plant does not tolerate wet feet, meaning that it should not be planted in areas with standing water or poor drainage.
Cultivation
The Pycnanthemum incanum (L.) Michx. var. puberulum (E. Grant & Epling) Fern., commonly known as Hoary mountain mint, is a hardy and robust perennial plant that can thrive in a variety of growing conditions. It prefers full sun exposure, but it can tolerate partial shade as well. The plant grows best in well-drained soil with a pH level between 6.0 and 7.5. It can grow up to 3 feet tall, and its blooms typically appear from June to August.
When planting Hoary mountain mint, make sure to space each plant about 18 inches apart to allow ample room for growth. The best time to plant is in spring or fall when the temperatures are cooler. You can plant the seedlings or propagate from cuttings.
Watering Needs
Hoary mountain mint is a drought-tolerant plant that can survive in various conditions, making it low maintenance. Young plants will require regular watering until they establish themselves. However, once established, they require occasional watering only during prolonged periods of dry weather. Too much water can lead to root rot, so it's essential to ensure that the soil drains well.
Fertilization
Hoary mountain mint is not a heavy feeder and can grow well without fertilization. However, to maximize growth, you can add a slow-release fertilizer in spring. Make sure not to apply too much fertilizer, as excessive nitrogen can lead to lush foliage and fewer blooms.
The best fertilizer for Hoary mountain mint is a general-purpose balanced fertilizer, such as a 10-10-10 or 20-20-20. Apply the fertilizer at the base of the plant, and water it in thoroughly. Avoid getting the fertilizer on the foliage, as it can burn the leaves.
Pruning
Pruning is crucial for maintaining the shape and appearance of Hoary mountain mint. You can pinch back the growing tips early in the season to promote bushier growth and more blooms. Deadheading the spent flowers will also encourage the plant to produce more blooms. If the plant begins to look leggy, you can cut it back to about half its height. This will also help rejuvenate the plant and promote new growth.
In fall, you can cut back the plant to just above the ground. This will help prevent the plant from becoming woody and provide new growth the following season.
Propagation of Pycnanthemum incanum (L.) Michx. var. puberulum (E. Grant & Epling) Fern.
Pycnanthemum incanum (L.) Michx. var. puberulum (E. Grant & Epling) Fern., also known as Hoary mountain mint, can be propagated by division and seed.
Propagation by Division
The plant can be divided in the spring by carefully digging up the clump and dividing it into smaller sections. Each section should have a healthy root system and several stems. Replant the divisions at the same depth they were growing before and water thoroughly. Dividing the clump will not only propagate the plant but also rejuvenate it for better growth and blooming.
Propagation by Seed
Propagation by seed is a reliable method to increase the number of plants, but it takes longer to establish as the plants mature slower from seed. Collect the seeds in the fall when the seed heads are fully mature. Allow the seed heads to dry on the plant, and then harvest them by cutting the stem just below the seed head. Clean the seeds by removing the chaff and store them in a dry and cool place until spring or the time to sow them arrives. Sow the seeds in the spring, either directly in the garden bed or start the seeds indoors. If starting inside, sow the seeds in moist soilless mix and maintain soil moisture levels until germination when the plants will need light for growth. When the seedlings have grown sizable enough, transplant them to a larger container or the garden bed
