Overview
Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf, commonly known as Bigelow's tobacco, is a flowering plant that is native to the southwestern United States and northern Mexico. It is a member of the family Solanaceae, the nightshade family, and is closely related to other tobacco species such as Nicotiana tabacum, which is grown commercially for tobacco production.
Description
Bigelow's tobacco is a herbaceous annual plant that can reach a height of up to 3 feet (1 meter). It has a branching stem and large, broad leaves that are coated in sticky hairs. The flowers are trumpet-shaped and can be white, pink, or lavender in color. They are borne in clusters at the top of the stem and attract a variety of pollinators, including bees and hummingbirds.
Common Names
Bigelow's tobacco is commonly known by several other names, including desert tobacco, multivalent tobacco, and cutleaf tobacco.
Uses
Bigelow's tobacco has been used traditionally by indigenous groups for medicinal and ceremonial purposes. The leaves of the plant can be smoked or made into a tea, which is said to have relaxing and sedative effects. However, it is important to note that the plant contains nicotine, which is a highly addictive substance and can be toxic in high doses. Therefore, it should not be used without proper guidance and supervision.
Light Requirements
Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf is a plant that requires full sun exposure to thrive. This type of plant enjoys bright sunlight, and it is best suited for areas with at least six hours of direct sun every day. A lack of light can make the plant susceptible to diseases and pests, which can eventually lead to death.
Temperature Requirements
The plant is native to the southwestern United States and northern Mexico, so it grows well in warm and dry climates. In general, the plant requires temperatures between 60°F and 85°F to grow and thrive. If the temperature becomes too hot, the plant may stop growing, wither or die. In addition, frost can also damage or kill this plant.
Soil Requirements
Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf grows best in well-drained soils with a pH between 6.0 and 8.0. The soil should be rich in organic matter, and the plant requires regular watering to maintain adequate soil moisture. Overwatering or drought can lead to root rot or wilting of this plant.
Cultivation Methods for Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf
When cultivating Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf, it is essential to note that this plant is native to the southwestern region of the United States. Hence, it grows best in warm and dry conditions with plenty of sunshine. Therefore, select a spot in your garden that receives full sun exposure and has well-draining soil.
You can propagate Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf from seeds or cuttings. If you choose to grow the plant from seeds, plant them in early spring while ensuring that the soil is moist but not waterlogged. Cover the seeds with a thin layer of soil and place them in a location that receives plenty of sunlight. Seeds can take anywhere between 10 to 14 days to germinate.
Watering Needs for Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf
Although Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf is drought-tolerant, it still requires frequent watering, especially during the first few weeks after planting. Water the plant deeply and slowly to promote root growth, and ensure the soil stays moist but not waterlogged. Remember to water earlier in the day to prevent the growth of fungi and other diseases.
Once the plant is established, it requires less frequent watering. You can reduce the watering frequency to once or twice a week, depending on the weather conditions. During hot summer months, the plant may require more frequent watering.
Fertilization of Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf
To promote healthy growth, Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf requires regular fertilization. In early spring, apply a slow-release fertilizer that is high in nitrogen to promote foliage growth. You can also fertilize the plant during the blooming stage to encourage more flowers.
Avoid applying too much fertilizer, as it can lead to excessive foliage growth at the expense of flowers. Follow the manufacturer's instructions for application rates to avoid over-fertilization.
Pruning Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf
Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf requires minimal pruning. However, you can remove any dead or yellowing leaves to promote healthy foliage growth. Pinch off spent blooms to encourage the growth of new flowers.
During the fall, after the first frost, you can prune the plant back to a few inches above the soil to prepare it for the winter season. This pruning encourages new growth in the spring.
Propagation of Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf
Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf, also known as Bigelow's tobacco, is a plant species that belongs to the family of Solanaceae. This plant species is native to the southwestern United States and northern Mexico, and it is commonly propagated by seeds or cuttings.
Seed Propagation
Bigelow's tobacco can be easily propagated from seeds. The seeds can be collected from mature fruit capsules and stored in a cool and dry place until planting. Alternatively, the plants can be allowed to self-seed in their natural habitat. When propagating from seeds, it is recommended to start the seeds indoors about 6-8 weeks before the last expected frost date. The seeds can be sown in a well-draining potting mix and kept moist until they germinate. Once the seedlings are large enough to handle, they can be transplanted into individual pots or directly into the ground.
Cutting Propagation
Bigelow's tobacco can also be propagated from stem cuttings. The best time to take cuttings is during the growing season in the spring or summer. The cuttings should be about 4-6 inches long and taken from healthy, disease-free plants. The lower leaves should be removed, and the cuttings should be dipped in a rooting hormone before being planted in a well-draining potting mix. The cuttings should be kept moist and in a warm, humid environment until they develop roots. Once the cuttings have rooted, they can be transplanted into individual pots or directly into the ground.
Overall, the propagation of Nicotiana quadrivalvis Pursh var. bigelovii (Torr.) DeWolf can be easily achieved through seed or cutting propagation methods.
