Common Names
Artemisia borealis Pallas var. latisecta Fern. is commonly known as Northern Wormwood, Broadleaf Sagewort, and White Sage.
Uses
The plant has several medicinal uses, such as treating stomach ailments and fevers. It is also an effective insecticide. The leaves and stems can be used to make tea, and the plant's fragrance can repel mosquitoes and other insects.
Artemisia borealis Pallas var. latisecta Fern. is also used in landscaping, adding visual interest and texture to garden beds. The plant has silvery gray foliage and grows up to 3 feet tall with a spreading, bushy habit.
General Appearance
Artemisia borealis Pallas var. latisecta Fern. is a herbaceous perennial that grows up to 3 feet tall and 6 feet wide. The leaves are alternate, lacy, and silvery gray, with deeply lobed edges. The plant produces small, yellow, disk flowers that bloom in late summer, which attract pollinators such as butterflies and bees. The plant prefers full to partial sun and well-drained soil.
Light Requirements
Artemisia borealis Pallas var. latisecta Fern. requires full sun exposure to thrive. It grows best in areas with at least six to eight hours of direct sunlight daily. When grown in shaded areas, the plant tends to be weak and leggy.
Temperature Requirements
The plant is found in areas with temperatures ranging from cold to cool and moist. It has been observed to grow in regions with annual mean temperatures of 8.0 – 16.5 °C. Artemisia borealis Pallas var. latisecta Fern. can withstand temperatures below freezing point during winter months. However, it may be severely damaged if exposed to temperatures above 30°C for extended periods.
Soil Requirements
The plant prefers well-draining and sandy soils with a pH of 6.0 – 7.5. Artemisia borealis Pallas var. latisecta Fern. is tolerant of poor soil conditions and can grow in soils with low fertility. Avoid planting in waterlogged areas as it may lead to root rot, which may kill the plant. Incorporate organic matter into the soil to improve its quality and support the growth of the plant.
Cultivation Methods
Artemisia borealis Pallas var. latisecta Fern. is best cultivated in a well-draining soil that is rich in humus and retains moisture. The best time to plant is during spring or fall, and the plant prefers to be grown in full sun or partial shade conditions. It is recommended to propagate the plant through rooted stem cuttings or by sowing seeds.
Watering Needs
The watering needs of Artemisia borealis Pallas var. latisecta Fern. are moderate. It prefers moist soil, but overwatering can lead to root rot and other fungal diseases. It is important to maintain the soil moisture level by watering once or twice per week and only if necessary.
Fertilization
The plant does not require frequent fertilization, as it can thrive in nutrient-poor soil. However, applying a balanced fertilizer in the spring can help with healthy growth. It is important to avoid over-fertilizing, as this can lead to excessive growth and poor flowering.
Pruning
Artemisia borealis Pallas var. latisecta Fern. does not require heavy pruning. However, it is recommended to prune back the plant by about a third during early spring to promote new growth and to prevent the plant from becoming woody or leggy. Regular pinching of the tips can encourage bushier growth and a fuller plant.
Propagation of Artemisia borealis Pallas var. latisecta Fern.
Artemisia borealis Pallas var. latisecta Fern. can be propagated by cuttings, division, and seed.
Cuttings
An easy way to propagate Artemisia borealis Pallas var. latisecta Fern. is through stem cuttings. Take 5-6-inch-long stem cuttings in spring or fall, remove the leaves from the bottom 2 inches of the stem, and plant the cuttings in a well-draining soil mix. Keep the soil moist, but not waterlogged, and in a covered area with indirect light until they root, which usually takes about 4-6 weeks.
Division
Artemisia borealis Pallas var. latisecta Fern. can also be propagated through division. This method is best done in the spring, just as new growth is beginning. To divide the plant, lift it from the ground and gently separate the root ball into smaller sections, each with its own roots and stems. Replant the divisions in well-draining soil in a partially shaded area and keep the soil moist until new growth appears.
Seed
Artemisia borealis Pallas var. latisecta Fern. can be grown from seed, though it can be difficult to find and may require stratification. Collect the seeds in late fall or early winter when they have turned brown and plant them in trays of seed starting mix. Keep the soil moist and put the trays somewhere with indirect light until the seedlings emerge. Once the seedlings reach a height of about 2 inches, transplant them into individual pots and keep them in a partially shaded area until they are ready to be planted in their permanent location.
Disease Management
Artemisia borealis Pallas var. latisecta Fern. is relatively resistant to diseases and pests, but some issues may arise in certain conditions. Here are some common diseases that might affect the plant and ways to manage them:
Leaf blight
Leaf blight is a common fungal disease that affects many plants, including Artemisia borealis Pallas var. latisecta Fern. Symptoms of this disease include brown or black spots on the leaves, which then turn yellow and die. The fungus spreads through water and can survive on plant debris and soil. To manage this disease, you should remove the infected leaves and destroy them. You can also use a fungicide, but make sure to follow the instructions carefully.
Powdery mildew
Powdery mildew is another fungal disease that can affect Artemisia borealis Pallas var. latisecta Fern. This disease appears as a white, powdery coating on the leaves that can eventually cause them to wilt and die. The fungus thrives in humid conditions, so you should avoid overhead watering and improve air circulation around the plant. You can also apply a fungicide, but make sure to choose one that is specifically designed for powdery mildew.
Pest Management
Artemisia borealis Pallas var. latisecta Fern. is relatively resistant to pests, but some may still cause problems. Here are some common pests that might affect the plant and ways to manage them:
Aphids
Aphids are small insects that feed on the sap of the plant, causing the leaves to curl and distort. They also excrete a sticky substance called honeydew, which can attract other pests and cause fungal diseases. To manage aphids, you can spray the plant with a strong jet of water to knock them off or apply an insecticidal soap. You can also introduce natural predators, such as ladybugs or lacewings, to help control the population.
Spider mites
Spider mites are tiny pests that feed on the plant's juices, causing the leaves to become dry and yellow. They are most common in hot, dry conditions and can quickly reproduce, making infestations difficult to control. To manage spider mites, you can spray the plant with water and increase the humidity around it. You can also apply a miticide if the infestation is severe, but make sure to follow the instructions carefully.
