It can withstand freezing temperatures and can survive in places where the temperature falls as low as -40°C. It can also survive in warm temperatures of up to 25°C though it prefers cooler temperatures.
Soil Requirements
Antennaria angustifolia Ekman, non Rydb. prefers well-drained soil that is rich in organic matter. It can grow in a range of soil types including sandy, loamy, and clay soils. However, the pH level of the soil should be slightly acidic to neutral, ranging from 6.0-7.5. This plant does not tolerate waterlogging and hence requires soil that does not retain too much water.
Cultivation Methods
Antennaria angustifolia Ekman is a low-growing plant that prefers well-draining soil. It can be grown outdoors in rock gardens, crevices, and alpine areas. The plant thrives in full sun to partial shade positions.
It is important to note that this plant cannot tolerate high heat and humidity. Thus, it is best to cultivate this plant in locations with lower temperature and better humidity levels.
Watering Needs
This plant requires moderate watering. Water the plant when the soil is dry to a depth of 1-2 inches. Make sure not to over-water the plant, as this can lead to root rot. During the winter months, water the plant sparingly.
Fertilization
The plant does not require excessive fertilization, but it is important to provide it with nutrients bi-annually. Use a balanced fertilizer to provide adequate nutrients to the plant. Don’t fertilize the plant during the winter season.
Pruning
Pruning is not necessary for this plant. However, you can pinch back the growing tips to promote a fuller plant growth and avoid any legginess. It is essential to remove any dead or diseased leaves or stems to prevent any further damage. Regularly check the plant for signs of pest infestations and treat them immediately to avoid any serious problems.
Propagation of Antennaria angustifolia Ekman, non Rydb.
Antennaria angustifolia Ekman, non Rydb., commonly known as narrowleaf pussytoes or ladies' tobacco, is a small herbaceous plant that can be propagated by several methods:
Seed propagation
One way to propagate Antennaria angustifolia is through seed propagation, which can be done indoors or outdoors. Sow the seeds in a seed tray or directly in the ground after the last frost. The seeds need light to germinate, so do not bury them deep. Keep the soil moist, and the seeds will germinate in about 10 to 14 days. Once the seedlings have grown several sets of leaves, they can be transplanted to their permanent location.
Division
Another propagation method for Antennaria angustifolia is through division. This can be done in early spring or fall. Dig up the plant and gently separate the clumps into smaller sections, making sure that each section has some roots. Replant the divided clumps in their permanent location and water them appropriately.
Cutting propagation
Antennaria angustifolia can also be propagated through cutting propagation. Take stem cuttings from mature plants in early summer and root them in a rooting hormone and moist soil. Once the cuttings have developed roots, they can be transplanted to their permanent location.
Tissue culture propagation
Finally, Antennaria angustifolia can be propagated through tissue culture. This method involves taking a small piece of the plant and growing it in a sterile environment on a nutrient-rich agar medium. Once the plant has grown roots and is able to sustain itself, it can be transplanted to its permanent location.
