Propagation of Artemisia ludoviciana Nutt. ssp. typica Keck
Artemisia ludoviciana Nutt. ssp. typica Keck, also known as Louisiana white sage, is a herbaceous plant that belongs to the Asteraceae family. It is native to North America and is commonly found in grasslands, prairies, and open woodlands. Propagation of this plant can be done through various methods.
Propagation by Seeds
Seeds are the most common method used for propagating Artemisia ludoviciana. Collect mature seeds from the plant during fall or winter after the seed heads have dried up. Clean the seeds and store them in a cool, dry place until planting time. You can sow the seeds indoors in pots or directly outdoors in the soil. Plant the seeds at a depth of 1/8 inch and keep the soil moist until the seeds germinate, which can take between 2-3 weeks. Once the seedlings have grown larger, you can transplant them to their permanent location.
Propagation by Cuttings
Another propagation method for Artemisia ludoviciana is through stem cuttings. Cut a stem from a healthy plant about 4-6 inches tall. Remove the lower leaves, leaving only a few leaves at the top. Dip the cut end of the stem in rooting hormone and plant it in a pot or directly in the soil. Keep the soil moist and wait for roots to develop. This can take a few weeks to a few months. Once roots have developed, transplant the cutting to its permanent location.
Propagation by Division
Division is a propagation method that should be done during the spring season when new growth appears. Dig up the plant and gently separate the roots into 2-3 sections. Replant each section in its permanent location, ensuring that each division has enough roots to survive.
Overall, Artemisia ludoviciana Nutt. ssp. typica Keck is an easy plant to propagate, and with the right care and conditions, it will grow into a beautiful landscape plant that provides a lovely aroma and foliage.
Disease and Pest Management for Artemisia ludoviciana Nutt. ssp. typica Keck

Understanding and implementing proper disease and pest management will ensure the plant's longevity and excellent health.
Common Diseases
Artemisia ludoviciana Nutt. ssp. typica Keck is known to be affected by fungal and bacterial diseases such as:
- Leaf spot: This is a fungal disease that manifests itself in the form of brown spots on the plant's leaves. Infected plant matter should be pruned first, and then a fungicide such as copper sulfate should be used to control the spread of the disease.
- Powdery mildew: This is another fungal disease that affects the leaves of the plant. It presents as a white powdery substance on the leaves. Prune the infected parts of the plant and apply potassium bicarbonate or neem oil to prevent it from spreading.
- Crown rot: This is a fungal disease that causes the plant's roots to rot. The plant will lose its stability over time, and eventually, it will die. Avoid overwatering and, if detected, remove the infected plants to prevent other nearby plants from getting the disease.
Common Pests
Artemisia ludoviciana Nutt. ssp. typica Keck is also known to suffer from pest infestations, such as:
- Aphids: These insects cause the plant's leaves to crinkle and curl. They can be effectively controlled by releasing beneficial insects such as ladybugs who feed on aphids. Alternatively, a mixture of water and soap can be sprayed onto the plants.
- Spider Mites: These pests are tiny and difficult to spot, but they can cause significant damage to the plant. Regular hose-downs can go a long way in preventing and controlling infestations.
- Cutworms: These pests are known to cut the plant stems and feed on the leaves. They are easily controlled by placing barriers around the plant's base to disrupt their travel.
In conclusion, regular monitoring and early detection of infestations and diseases are crucial in the proper management of Artemisia ludoviciana Nutt. ssp. typica Keck.
