Description

(Pycnanthemum pilosum) This top pollinator favorite is easy to grow from seed and to care for. It's loaded with nectar, so the subtly spotted flowers hum with life. Because of its strong smell, mammals won't bother it, yet it's a delight in the gardens because simply brushing this plant will release a beautiful mint aroma. The first botanical records of this plant come from French botanist Andre Michaux's notes from the late 18th century. It naturalizes in dry prairie or glade habitats, but also does well in sunny to partially shaded, drained beds. It can readily spread by rhizomes, but roots can be cut back once a year to prevent spreading.

Growing Tips: Mountain mint thrives best in environments that provide full sun to partial shade and well-draining soil. Although it can tolerate drought once established, consistent watering during its initial growth stages is crucial. Mulching around the plants helps in retaining soil moisture and suppressing weed growth. To manage the plant's natural spread through underground rhizomes, consider planting it in containers or regularly trimming the roots around the plant's perimeter.

When to Grow

The ideal time to plant Mountain mint is in the spring, post the last frost, though it can also be planted in late summer or early fall. It is a hardy perennial in USDA zones 4-8, making it adaptable to a variety of climates. Ensure the soil is well-drained and provide moderate watering until the plant is fully established to encourage robust growth​.

How to Sow and Plant

Sow the seeds on the soil surface as they require light for germination, keeping the soil moist and maintaining a temperature of 65-75 F until germination occurs. Transplant seedlings outdoors once they have a couple of sets of true leaves and the danger of frost has passed. Space them about 12 inches apart to allow for adequate airflow and growth. You can limit spread by creating root barriers in the soil, or grow in containers off the ground.

How to Grow

Once established, mountain mint is quite drought-tolerant but appreciates regular watering during dry periods to maintain optimal health. Be careful not to overwater, as this can lead to root rot. Fertilization is typically minimal; if the soil quality is poor, a balanced, slow-release fertilizer applied in the spring can provide the necessary nutrients. Regular pruning in early spring helps maintain a compact shape and encourages bushier growth. Additionally, trimming the plant after flowering can stimulate a second flush of growth, ensuring continuous vitality throughout the growing season​.

How to Save Seeds

  • Seeds are mature once the flower heads have fully dried and turned brown. To harvest them, cut the flower spikes and place them inside a paper bag. This allows the seeds to completely dry and drop; you may need to shake the bag gently to help loosen the seeds. Afterward, separate any chaff from the seeds and store them in a cool, dry place.
  • Many people prefer propagating mint plants through cuttings as it is generally easier than growing from seeds. Simply take a cutting from a healthy plant, remove the lower leaves, and place it in water until roots develop. Then, plant it in the soil.
