Overview
Heuchera parviflora Bartl. is a flowering plant commonly known as the American alumroot. It belongs to the Saxifragaceae family and is native to the Rocky Mountains of North America.
Description
The plant has a compact growth habit and produces basal rosettes of deep green, lobed leaves that are hairy on the underside. The leaves form a mound that is about 6 inches tall and 12 inches wide. The plant produces stalks of tiny, bell-shaped flowers that are a pinkish-lavender color. The flowers appear in mid-summer and are held above the foliage on wiry stems that are up to 18 inches tall.
Common Names
Other common names for Heuchera parviflora Bartl. include small-flowered alumroot and littleflower alumroot.
Uses
Heuchera parviflora Bartl. is often grown as an ornamental plant in rock gardens or as a border plant. It is also a great choice for planting in containers. The plant is low maintenance and tolerant of a wide range of growing conditions. The leaves can be used in salads and other culinary dishes as they have a slight peppery taste.
Medicinally, the plant has astringent properties and has been used by Native American tribes to treat wounds, eczema, and internal bleeding. The roots were used to make a tea to help treat mouth sores and sore throats.
Light Requirements
Heuchera parviflora Bartl. grows best in partial shade to full shade conditions. It can tolerate some direct sunlight in the morning or evening, but too much direct sun can damage the leaves and cause them to wilt.
Temperature Requirements
Heuchera parviflora Bartl. is native to the mountains of Central Europe and can tolerate cold temperatures. It grows best in cool, temperate conditions, with optimal temperatures ranging from 12°C to 18°C (54°F to 64°F). It can tolerate occasional frosts and snow but may struggle in very hot, humid environments.
Soil Requirements
Heuchera parviflora Bartl. prefers well-draining, moist soils with a slightly acidic pH range of 5.5 to 7.5. It can grow in a variety of soil types, including loam, sand, and clay soils. However, it is important to ensure that the soil does not become waterlogged as this can lead to root rot and other problems. Adding compost or other organic matter to the soil can help improve its fertility and drainage.
Cultivation methods
Heuchera parviflora Bartl. is a perennial plant that grows best in USDA hardiness zones 5 to 8. It prefers well-drained soil and partial to full shade. When planting, make sure to space the plants around one foot apart. This will ensure that the plants have enough room to grow and spread out.
Watering needs
This plant prefers consistently moist soil. Therefore, it is crucial to water it regularly, especially during the hot summer months. However, overwatering should be avoided.
One way to check if the soil is moist enough is to stick a finger into the soil up to the first knuckle; if the soil feels moist, then it does not need watering, but if it is dry, then it is time to give it some water.
Fertilization
Heuchera parviflora Bartl. does not require a lot of fertilization, but it benefits from occasional feeding. Use a balanced fertilizer during the growing season. Fertilize the plant in early spring before new growth emerges. Avoid overfeeding the plant as this can lead to weak growth.
Pruning
Pruning this plant is not necessary other than removing dead leaves and flowers. Cut the dead leaves and flowers back to the base of the plant to maintain its appearance. Prune the plant in early spring before new growth emerges or in the fall after the first frost.
If the plant has become too large or is overgrown, it can be divided in the spring or fall. Dig up the plant and separate the roots, then replant each section in a separate location.
Propagation of Heuchera parviflora Bartl.
Heuchera parviflora Bartl. can be propagated by different methods, including division and seed propagation. Different propagation methods can be used to increase the number of plants, produce new varieties, and maintain genetic diversity. These methods are easy to follow and can be done even by novice gardeners.
Division Propagation
Division is the simplest and most commonly used propagation method for Heuchera parviflora Bartl. This method involves dividing the parent plant into smaller sections and planting them separately. Division is done in early spring or fall when the plant is dormant or showing limited growth. The steps involved in division are:
- Carefully dig up the plant and remove any dead or damaged parts.
- Inspect the plant for natural divisions or sections where roots and shoots are growing separately.
- Using a sharp knife or garden shears, cut the plant into smaller sections ensuring that each section has a healthy root system and a growth point.
- Plant each section in a well-prepared soil mix and water thoroughly.
Seed Propagation
Seed propagation is another method of propagating Heuchera parviflora Bartl. This method involves collecting seeds from the parent plant and sowing them in a suitable growing medium. Seed propagation is slower and more unpredictable than division but is useful for producing new varieties and maintaining genetic diversity. The steps involved in seed propagation are:
- Collect the seeds from the parent plant after the flowers have dried up and the seed pods have matured.
- Clean the seeds and store them in a dry and cool place until ready to be sown.
- Sow the cleaned seeds in a well-prepared soil mix in a seedling tray or a greenhouse during early spring.
- Keep the soil moist and provide adequate light and air circulation for optimal growth.
- Transplant the seedlings into individual pots or garden soil when they are large enough to handle and have developed a strong root system.
Disease and Pest Management for Heuchera parviflora Bartl.
Heuchera parviflora Bartl. is relatively resistant to pests and diseases. However, it may still fall prey to some common issues that can affect its health and productivity. Here are some common diseases and pests that might affect the plant and suggestions on how to manage them:
Diseases
Leaf Spot: Leaf spot is caused by fungal pathogens and typically appears as brown-black spots on the leaves. It is common in wet conditions and can weaken the plant, making it more susceptible to other diseases and pests. To manage leaf spot, remove and destroy affected leaves, and ensure proper spacing between plants to improve air circulation.
Powdery Mildew: Powdery mildew is a white, powdery coating that forms on the leaves and stems of the plant. It thrives in warm, humid weather and can weaken the plant. To manage powdery mildew, remove affected plant parts, increase air circulation around the plant, and avoid overhead watering. Fungicides may also be used as a preventative measure.
Pests
Aphids: Aphids are small, pear-shaped insects that suck the sap from the plant, causing stunted growth and yellowing leaves. They can also transmit viruses. To manage aphids, spray with water to dislodge them, introduce natural predators like ladybugs or lacewings, or use insecticidal soap.
Snails and Slugs: Snails and slugs are mollusks that can devour large portions of the plant, leaving large holes in the leaves and weakening the plant. To manage them, handpick them off the plant, create a barrier around the plant with copper or diatomaceous earth, or use bait traps.
By closely monitoring Heuchera parviflora Bartl. for pests and diseases and taking prompt action when necessary, you can ensure that your plants are healthy and productive.
