Antennaria monocephala DC. var. exilis (Greene) Hultén can grow in both full sun and partial shade conditions. However, it is recommended to provide some shade during the hottest times of the day.
Temperature Requirements
Antennaria monocephala DC. var. exilis (Greene) Hultén is native to alpine and subalpine zones, and it is tolerant of cold temperatures. It prefers cool summers with average temperatures ranging from 15 to 20°C and cold winters with average temperatures ranging from -5 to 5°C.
Soil Requirements
The plant prefers well-drained, sandy, and porous soil that is rich in organic matter. It can grow in a wide range of soil pH levels, but slightly acidic to neutral soil with a pH range between 5.0 to 7.0 is preferred. It is also important to provide adequate irrigation or water retention in the soil during the growing season.
Cultivation
Antennaria monocephala DC. var. exilis (Greene) Hultén is a low-growing, herbaceous perennial plant that is well-suited for rock gardens, borders, or edging. This plant prefers well-draining, sandy loam soil but can also tolerate rocky or gravelly soil.
It should be planted in a location that receives full sun to partial shade, as too much shade can cause the plant to become leggy and weak.
Watering
Antennaria monocephala DC. var. exilis (Greene) Hultén prefers to be kept evenly moist, but not waterlogged. It is important to ensure that the soil is well-drained and not left to sit in excess water, as this can lead to root rot.
Water the plant deeply once or twice a week if there is no natural rainfall. In hot, dry climates or during periods of drought, it may be necessary to water more often.
Fertilization
Antennaria monocephala DC. var. exilis (Greene) Hultén does not require much fertilization, but it can benefit from a light application of fertilizer in the spring. Use a balanced, all-purpose fertilizer and apply it according to the manufacturer's instructions.
Over-fertilization can lead to excessive growth and may cause the plant to become too leggy and weak.
Pruning
Antennaria monocephala DC. var. exilis (Greene) Hultén does not require much pruning, but you can deadhead the flowers after they have finished blooming to promote more flowering throughout the growing season.
If the plant becomes too leggy or begins to flop over, it can be trimmed back by one-third in the early spring. This will promote bushier growth and help keep the plant compact and tidy.
Propagation of Antennaria monocephala DC. var. exilis (Greene) Hultén
Antennaria monocephala DC. var. exilis (Greene) Hultén, commonly known as the singlehead pussytoes, can be propagated via two methods: division and seed propagation.
Division
Division method is straightforward and can be done in late spring or early fall. Here are the steps:
- Carefully dig up the plant from the soil.
- Use a pair of sterile garden scissors to cut the root ball into smaller clumps.
- Transplant each clump into individual pots filled with a well-draining soil mix.
- Water the newly planted divisions until the soil is moist, but not soggy.
- Place the pots in a bright and well-ventilated area away from direct sunlight.
- Keep the soil moist and transplant the new plants into the garden when they have established a robust root system and have adequate foliage.
Seed Propagation
Seed propagation is the most popular method to propagate Antennaria monocephala DC. var. exilis. Follow these guidelines for the best success:
- Collect ripen seed heads from the plant in early fall, before the snow falls.
- Place the seed heads in a paper bag and store them in a cool and dry place until the following spring.
- Start seedlings indoors 6-8 weeks before the last frost.
- Fill small pots with a good quality seed-starting mix and water the soil until it is evenly moist.
- Use a toothpick to disperse two to three seeds onto the soil surface, then cover the seed with a thin blanket of soil.
- Keep the pots covered with plastic wrap or a clear plastic dome and place them in a well-lit area that does not receive direct sunlight.
- Maintain the soil moisture by misting regularly but avoid over-watering as it may cause the seed to rot.
- Transplant the seedlings into larger pots once they have produced 1-2 sets of true leaves.
- Move the plants outside when the temperature stabilizes above freezing.
- Plant the young plants in the garden when they have developed several sets of true leaves and strong root systems.
