Common Names
Besides Lake Huron tansy, this plant is also commonly known by other names such as tansy aster, fernleaf tansy, and Huron tansy.
Uses
The Tanacetum bipinnatum ssp. huronense has been used by Native Americans as a traditional medicine to treat conditions such as colds, fever, and headaches. The plant is also known to contain chemicals that repel insects, and as such, it has been used as an insecticide.
Additionally, the plant has ornamental uses and is grown for its attractive foliage. It can also be used in landscaping and as a ground cover.
General Appearance
The Tanacetum bipinnatum ssp. huronense is a perennial plant that grows up to 3 feet tall and 2 feet wide. It has gray-green, fern-like leaves that are finely divided and have a pungent odor when crushed. The plant produces clusters of yellow-orange flowers with disk-like centers that bloom in late summer and fall.
The plant has a spreading habit and creeps through the use of rhizomes. It is tolerant of a variety of soil conditions and light levels.
Light Requirements
Tanacetum bipinnatum ssp. huronense commonly grows in areas that receive full sunlight. The plant thrives in bright light conditions, making it an ideal candidate for growing in open areas, meadows, and in gardens exposed to sunlight. It requires about 6 hours of direct sunlight every day and can tolerate a wide range of light intensities.
Temperature Requirements
The plant is predominantly found in the central and eastern parts of North America, where it is accustomed to a temperate climate. Optimal growth temperature for Tanacetum bipinnatum ssp. huronense is between 15°C and 30°C. This temperature range supports its growth, ensuring that it can grow throughout the entire year as long as the temperatures are within the appropriate range.
Soil Requirements
Tanacetum bipinnatum ssp. huronense grows in a wide range of soils but does best in well-draining soils that are rich in nutrients. A slightly acidic soil pH between 6.0 and 7.0 is ideal for its growth. It can tolerate poor soils as well as dry soils once it has established itself, provided that the soil has some level of moisture. The plant is sensitive to waterlogging and requires proper drainage to prevent root rot.
Cultivation methods
Tanacetum bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung, commonly known as Hairy Leaf Tansy, is a hardy perennial herb that is native to North America. It is typically grown for its ornamental value, with clusters of yellow flowers that bloom from the middle of summer to the beginning of fall. To grow Tanacetum bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung successfully, you should consider the following cultivation methods:
- Ensure that the plant is grown in well-drained soil that has a pH of 6.0-7.0.
- Choose a sunny location since the plant prefers full sun.
- Plant in the spring or fall, making sure you space them out by 18-24 inches.
- Regularly weed and water the plants during the first year of growth to ensure they establish well.
Watering needs
Watering is an essential aspect of growing healthy and productive T. bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung. During the first year of growth, water regularly to establish the plants correctly and ensure good root development. After that, water only when the plant shows signs of wilting. Overwatering can lead to root rot and low-quality foliage. Ensure that the plants are watered at the base and not overhead to prevent the foliage from being continuously wet, which can encourage disease and pests.
Fertilization
Proper fertilization can benefit T. bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung growth and development. Use a balanced, slow-release fertilizer with ratios such as 10-10-10 or 14-14-14 for optimal results. Avoid high-nitrogen fertilizers since they encourage leafy growth at the expense of flowers. Fertilize the plants twice a year, once in the spring and once in the fall. Apply the fertilizer according to the manufacturer's instructions, making sure that the soil is moist before application.
Pruning
Pruning T. bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung regularly can help maintain the plant's shape and encourage more flowering. Deadheading the plant by removing spent flowers as soon as they die promotes the production of new blooms. Prune back the plant's stem in half during the midsummer season to encourage branching and a bushier plant. Finally, prune the foliage down to the ground in the late fall or early spring to ensure the plant regenerates well.
Propagation of Tanacetum bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung
Tanacetum bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung, also known as Doublefile Tanacetum, can be propagated through various methods such as seed propagation, root division, and stem cutting.
Seed Propagation
Seeds of Tanacetum bipinnatum can be directly sowed into a well-draining seed-raising mix in spring or summer when the soil is warm enough. The optimum temperature for seed germination is between 18-24°C. The seeds should be sowed at a depth of approximately 1-2 mm, and the soil should be kept moist throughout the germination period. Germination usually occurs within 14-28 days.
Root Division
Root division is another way to propagate Tanacetum bipinnatum. This method is best done in early spring or fall when the plant is not actively growing. To propagate using root division, dig up the plant and separate the clump into several sections, ensuring each section has a healthy root system. Replant the divided sections into a well-draining soil mix, spacing them at least 30cm apart. Keep the soil moist and avoid watering too much to prevent waterlogging.
Stem Cutting Propagation
Tanacetum bipinnatum can also be propagated through stem cuttings. Take 5-10 cm cuttings from healthy, non-flowering stems during the growing season. Remove the lower leaves, leaving only the top two to three leaves. Dip the cut ends into rooting hormone powder and insert them into a rooting mix. You can use peat moss, perlite, or sand to propagate the cuttings. Keep the mix moist, and place the cuttings in a bright, shaded area. Within about 2-4 weeks, the cuttings should start to develop roots.
Disease and Pest Management for Tanacetum Bipinnatum (L.) Schultz-Bip. Ssp. Huronense (Nutt.) Breitung
Tanacetum bipinnatum (L.) Schultz-Bip. ssp. huronense (Nutt.) Breitung, commonly known as Huron tansy, is a plant that belongs to the Asteraceae family. It is a herbaceous perennial that is native to North America and is often cultivated as an ornamental plant. Managing pests and diseases is an essential aspect of maintaining a healthy Tanacetum bipinnatum population.
Common Diseases
There are several diseases that can affect Tanacetum bipinnatum, including:
- Leaf Spot - A fungal disease that causes small, circular spots on the leaves, which may merge to form large patches. Fungicides containing chlorothalonil or mancozeb can be used to manage this disease.
- Root Rot - A fungal disease caused by Phytophthora or Pythium, which causes the roots to rot and the plant to wilt. Avoid over-watering and ensure proper drainage to prevent this disease.
- Powdery Mildew - A fungal disease that produces a white, powdery growth on the leaves and stems. Fungicides containing myclobutanil or propiconazole can be used to manage this disease.
Common Pests
There are several pests that can infest Tanacetum bipinnatum, including:
- Aphids - Tiny, pear-shaped insects that suck sap from the leaves and stems. They cause distorted growth and can spread viral diseases. Insecticidal soap, neem oil, or narrow-range oil can help manage aphids.
- Spider Mites - Tiny, red or brown mites that suck sap from the leaves, causing yellowing and eventual wilting. Insecticidal soap, neem oil, or predatory mites can help manage spider mites.
- Thrips - Tiny, slender insects that feed on the leaves, causing silvering and distortion. Insecticidal soap or neem oil can help manage thrips.
Preventive Measures
Prevention is always better than cure. Here are some preventive measures that can help manage diseases and pests in Tanacetum bipinnatum:
- Plant in well-drained soil with good air circulation to prevent root rot and foliar diseases.
- Prune and remove infected plant parts to prevent the spread of diseases.
- Maintain proper irrigation practices to prevent water stress and promote plant health.
- Grow companion plants, like chives, marigolds, or garlic, that repel pests.
- Regularly monitor for pests and diseases to catch them early and prevent an infestation.
By implementing these disease and pest management practices, you can help ensure a healthy and thriving Tanacetum bipinnatum population.
