Origin
Viola ×notabilis Bickn. (pro sp.), commonly known as the Canyon Violet, is a rare hybrid species found only in a few locations in the Rocky Mountains of North America, including Colorado, New Mexico, and Arizona.
Common Names
The plant is also known by other common names, such as San Juan Violet, Navajo Mountain Violet, and Rattlesnake Violet. These names reflect the plant's close association with the unique habitats of these regions.
Uses
The Canyon Violet is not known for any practical uses, although it was possibly used in Native American traditional medicine as a remedy for various ailments. However, this requires further research to confirm.
General Appearance
The Canyon Violet is a small, clump-forming perennial plant that grows up to 10 cm in height. It has dark green, lance-shaped leaves that are 3-4 cm long. The flowers of the plant have five petals that range in color from pale lavender to dark purple. The plant blooms from May to July and often produces a second flush of flowers in the fall. The Canyon Violet prefers rocky, well-draining soils in forests, canyons, and other shaded habitats.
Light Requirements
Viola ×notabilis Bickn. requires bright but filtered sunlight to grow properly. Direct sunlight can scorch the leaves of the plant. The plant can grow well in partial shade as well where it can receive at least 4-5 hours of bright sunlight daily.
Temperature Requirements
The plant grows well in cool temperature conditions. Optimum temperature range for the plant's growth is around 10 - 20°C (50-68°F). In hotter climates or during summer, the plant must be kept away from direct sunlight and needs watering more often.
Soil Requirements
The plant prefers well-draining, loamy soil, with a slightly acidic pH of around 5-6.5. The soil should contain organic matter, and it should be moist but not soggy. Adding compost or organic mulch to the soil can help to improve soil health, moisture retention, and soil structure. Alpine soil can also be used for the plant as it is rich and well-draining.
Cultivation
Viola ×notabilis Bickn. (pro sp.) prefers to grow in partial sunlight and well-drained soil. It is an excellent choice for rock gardens, borders, and containers. The plant is hardy in USDA zones 5 to 9 and is relatively easy to care for, making it an ideal choice for beginners and experienced gardeners alike.
Watering Needs
Viola ×notabilis Bickn. (pro sp.) requires moderate watering. The soil should be kept moist but not waterlogged. During the growing season, it is recommended to water the plant regularly and avoid letting the soil dry out completely. However, overwatering can lead to root rot, so be cautious not to overdo it.
Fertilization
Fertilizing the plant is recommended once a month from spring to early fall. Use a slow-release fertilizer that is balanced in nitrogen, phosphorus, and potassium, following the manufacturer's instructions. Though, it is important not to overfertilize, which could cause the foliage to grow too large and detract from the plant's beautiful flowers.
Pruning
Removing dead flowers not only prevents the plant from producing seeds but also encourages it to bloom for a longer time. Also, pruning helps to maintain the plant's shape and size by trimming back any unhealthy or overgrown stems. Pruning should be done in the summer, just after the first flush of flowers fade.
Propagation of Viola ×notabilis Bickn.
Viola ×notabilis Bickn. can be propagated by either seeds or vegetative means.
Propagation by Seeds
The seeds should be collected when they are fully developed and mature. The seeds should be sown in a well-draining soil mixture in either the fall or spring. The seeds should not be buried too deep into the soil and should be kept moist until they germinate. The germination process can take several weeks.
Propagation by Vegetative Means
Viola ×notabilis Bickn. can also be propagated by vegetative means such as stem cuttings. The stem cuttings should be taken from healthy plants during the spring or early summer. The cuttings should be about 4-6 inches long and should be taken from the current year's growth. The cuttings should be planted in a well-draining soil mixture and watered regularly. The cuttings will root and start to grow within a few weeks.
Another way to propagate Viola ×notabilis Bickn. is by division. The plant can be divided in either the fall or spring when the plant is not actively growing. The plant should be dug up and carefully separated into clumps. Each clump should have healthy roots and shoots. The clumps should be planted in well-draining soil and kept moist until they establish themselves.
Disease and Pest Management for Viola ×notabilis Bickn.
Viola ×notabilis Bickn. is a hybrid plant that is relatively resilient to diseases and pests. However, it is still susceptible to certain issues that can affect its health and appearance. Here are some of the common diseases and pests that might affect Viola ×notabilis Bickn. and ways to manage them:
Diseases
Leaf spot: Viola ×notabilis Bickn. may develop leaf spot, which is a fungal disease that causes circular or irregularly shaped brown spots on the leaves. To manage leaf spot, it is important to remove infected leaves and avoid wetting the foliage when watering the plant. Consider applying a fungicide if the problem persists.
Downy mildew: Downy mildew is another fungal disease that affects Viola ×notabilis Bickn. The disease causes yellow or pale green patches on the leaves, which eventually turn brown. To manage downy mildew, it is important to improve air circulation around the plant and avoid overhead watering. Consider applying a fungicide if necessary.
Pests
Aphids: Aphids are a common pest that can affect Viola ×notabilis Bickn. These small insects suck the sap from the plant, causing the leaves to become distorted and yellow. To manage aphids, consider blasting them with water or application of insecticidal soap.
Slugs and snails: Slugs and snails are another common pest that can affect Viola ×notabilis Bickn. These pests feed on the leaves, stems, and flowers of the plant. To manage slugs and snails, consider removing any debris or hiding spots around the plant and using traps or baits to catch them.
Overall, preventing diseases and pests is the best way to maintain the health and beauty of Viola ×notabilis Bickn. Regularly monitor your plant for any signs of issues and take prompt action to manage them. By following these tips, you can help ensure that your Viola ×notabilis Bickn. plant thrives.
