Origin
Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry, also known as Harrison's stickseed, is native to the western United States. It can be found in regions such as the Great Basin and Rocky Mountains, as well as parts of California, Nevada, Oregon, and Idaho.
Common Names
Harrison's stickseed is also commonly referred to as Harrison's beggarticks, Harrison's stickseed forget-me-not, or simply stickseed. These names are based on the plant's seeds, which have a long, slender shape and tiny hooks that stick to clothing and animal fur, allowing for easy dispersal.
Uses
While not commonly used for medicinal or culinary purposes, Harrison's stickseed is valuable for its ability to attract pollinators such as bees and butterflies. Additionally, the plant's seeds provide a source of food for birds and small mammals.
General Appearance
Harrison's stickseed is a herbaceous, biennial plant that can grow up to 3 feet tall. Its leaves are lance-shaped and covered in fine hairs, while its stems are tall and slightly branched. The plant produces clusters of small, blue flowers with five petals that bloom from May to September. After flowering, the plant produces long, narrow seed pods that can measure up to 1 inch in length. These pods contain numerous seeds with tiny hooks that aid in dispersal. Overall, Harrison's stickseed is an attractive plant that makes a good addition to wildflower gardens.
Light Requirements for Hackelia patens var. harrisonii
Hackelia patens var. harrisonii grows well in full sun to partial shade. However, partial shade may increase the height of the plant likely due to the increase in internode length. Studies have shown that individuals in partial shade tend to have more leaves and flowers since the energy is directed upwards. When growing the plant indoors, it is recommended that you provide supplementary lighting to ensure the plant receives adequate light.
Temperature Requirements for Hackelia patens var. harrisonii
Hackelia patens var. harrisonii is a hardy annual that grows well in cool temperatures. The plant can tolerate temperatures as low as -10°C (14°F) and as high as 35°C (95°F), however, temperature extremes can negatively impact the plant's growth and flowering. Ideally, the plant should be grown in temperatures between 15°C (59°F) and 25°C (77°F). The plant's flowering is significantly delayed at higher temperatures, so growers should aim for lower to moderate temperatures for optimal growth.
Soil Requirements for Hackelia patens var. harrisonii
Hackelia patens var. harrisonii prefers well-draining soils. Sandy soils are ideal, but the plant can also grow in clay, loam, and gravel. The plant requires a neutral to slightly acidic pH range between 6.0 and 7.5. Since the plant is intolerant to drought, the soil must have a high moisture content, but it must not be waterlogged. Fertilizer may be applied during transplanting, but it is not necessary since the plant prefers nutrient-poor soils. Mulching the plant can help to maintain moisture in the soil and keep the roots cool during hot weather.
Cultivation Methods
Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry is a hardy perennial plant that is typically grown in full sun to partial shade. It prefers well-drained soil and can tolerate a range of soil types. The plant can be grown from seeds or propagated through division.
If propagating through division, separate the plant in early spring before new growth emerges. Dig around the base of the plant, being careful not to damage the roots, and gently separate the plant into smaller sections using a sharp tool. Replant the divisions in well-draining soil at the same level they were previously planted.
Watering Needs
Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry prefers slightly moist soil and should be watered regularly during the growing season. Water the plant deeply once or twice a week, depending on rainfall and temperature, to ensure the root system is hydrated. Avoid overwatering, which can lead to root rot.
Fertilization
Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry does not typically require fertilization. However, if you wish to encourage faster growth or more prolific blooms, you can fertilize the plant with a balanced, all-purpose fertilizer once in the spring. Follow the manufacturer's instructions for application rates and methods, being careful not to overfertilize.
Pruning
Pruning of Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry is generally not necessary. Deadheading spent blooms can encourage the plant to produce new blooms and help maintain its shape. You can also remove any damaged or diseased foliage and stems as necessary. Perform any necessary pruning in late fall or early spring.
Propagation of Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry
Hackelia patens (Nutt.) I.M. Johnston var. harrisonii J.L. Gentry is commonly known as Appalachian stickseed. It is a native perennial plant of the eastern United States. The plant has blue flowers and is about 2-4 feet tall. It grows well in both dry and moist soils and prefers partial to full sunlight.
Propagation of Hackelia patens can be done using several methods, including seed propagation, stem cuttings, and division. Each method has its own unique advantages and disadvantages.
Seed propagation
The most common method of propagating Hackelia patens is through seed propagation. The best time to plant the seeds is in the fall or winter. You can scatter the seeds over the soil surface and press them down gently. Keep the soil moist until the seedlings germinate, which takes about 2-3 weeks. Once the seedlings have grown to a size of 2-3 inches tall, you can transplant them to their permanent location.
Stem cuttings
Another method to propagate Hackelia patens is through stem cuttings. Take a cutting from the stem of the plant, preferably during late spring or early summer. Place the cutting in a pot with moist soil and keep the soil moist. After a few weeks, new roots will form, and the plant can be transplanted to its permanent location.
Division
Division is another method of propagating Hackelia patens. This method involves dividing the plant into smaller sections and transplanting them. Divide the plant during early spring or late fall, when it is not in full bloom. Carefully lift the plant out of the ground and separate the individual sections. Ensure that each section has enough roots and leaves. Transplant the sections to their permanent location and keep the soil moist.
Disease and Pest Management for Hackelia Patens (Nutt.) I.M. Johnston var. Harrisonii J.L. Gentry
Hackelia Patens (Nutt.) I.M. Johnston var. Harrisonii J.L. Gentry, commonly known as Harrison's stickseed, is a herbaceous perennial plant that is native to North America. While Harrison's stickseed is not typically affected by pests or diseases, there are still some management strategies that can be used to ensure the health of the plant.
Diseases
One common disease that can affect Harrison's stickseed is powdery mildew. Powdery mildew appears as a white powdery coating on the leaves, stems, and flowers of the plant. To manage this disease, it is recommended to avoid overhead watering, as water droplets on the leaves can create a favorable environment for the disease to develop. Instead, use drip irrigation to water the plant at the soil level. Additionally, removing infected plant materials and maintaining good airflow around the plant can help prevent the spread of powdery mildew.
Root rot is another potential disease that can affect Harrison's stickseed. Root rot is caused by soilborne fungi, and it can cause the plant to wilt and eventually die. To prevent root rot, make sure that the plant is not overwatered and that the soil is well-drained. It is also important to remove any infected plant materials promptly to prevent the spread of the disease.
Pests
While pests are not typically a major concern for Harrison's stickseed, there are still some that can be problematic. One potential pest is the spider mite. Spider mites can cause yellowing and discoloration of the leaves, as well as webbing. To manage spider mites, it is recommended to use insecticidal soap or neem oil, which can be sprayed directly on the plant to help control the infestation.
Another pest that can be problematic for Harrison's stickseed is the slugs and snails. These pests can cause damage to the foliage and flowers of the plant. To manage these pests, it is recommended to use slug and snail baits or traps. Additionally, removing any debris or mulch that can provide a hiding place for the pests can help reduce their population.
