Rosendahl, Butters & Lakela, commonly known as small-flowered alumroot, is a hardy herbaceous perennial that grows in a wide range of conditions. This native plant to North America has oval-shaped, scalloped foliage and produces pink or white flowers on tall stalks from early spring to late summer.
Light Requirements
Heuchera micrantha var. diversifolia prefers partial to full shade but can tolerate some direct sun in the morning or evening. Too much direct sunlight can scorch the foliage and negatively impact growth and flowering.
Temperature Requirements
Small-flowered alumroot is adaptable to a variety of temperature conditions but prefers cooler temperatures. Optimal temperature range for growth is between 50°F to 70°F, and the plant can tolerate temperatures as low as 20°F.
Soil Requirements
The soil that supports the growth of Heuchera micrantha var. diversifolia should be well-draining and rich in organic matter. The plant prefers slightly acidic soil with a pH range between 6.0 and 7.0. It is essential to ensure that the soil is moist, but not waterlogged, as the roots of the plant can rot if left in standing water.
Cultivation
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela is a hardy plant that can adapt to different soil conditions. It prefers well-draining soil that is rich in organic matter and acidic to neutral in pH. It can thrive in full sun to partial shade, but it performs best in partial shade. This plant is suitable for USDA hardiness zones 4 to 9.
When planting, ensure that the crown of the plant is level with the soil surface. Space the plants about 12 to 18 inches apart, which will give them enough room to spread. After planting, water the plant thoroughly and add a layer of mulch around the base to retain moisture.
Watering Needs
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela requires moderate watering. Water the plant deeply about once a week, especially during hot and dry weather, to encourage root growth. Allow the soil to dry slightly between watering to avoid waterlogging, which can lead to root rot. Overwatering can also cause the plant to lose its vigor and become more susceptible to diseases.
Fertilization
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela requires low to moderate fertilization. Apply a balanced fertilizer once a year in early spring or fall. Avoid fertilizing during the summer because it can promote soft growth, which is prone to pest and disease problems. Over-fertilizing can also lead to excessive growth, which can overshadow the plant's beautiful foliage.
Pruning
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela does not require regular pruning. However, you can remove any dead or damaged leaves throughout the growing season to maintain the plant's appearance. You can also cut back any spent flower stems to promote new growth and encourage more flowering. Pruning is best done in the spring when the new growth emerges.
Propagation of Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela, commonly known as the diversity-leaved alumroot, can be propagated through several methods.
Seed Propagation
Propagation through seeds is the most commonly used method for Heuchera micrantha Dougl. ex Lindl. var. diversifolia. The seeds should be collected early in the autumn, and then thoroughly cleaned to ensure that no debris is present. After cleaning, the seeds should be stored in a cool and dry place. In the spring, the seeds can be planted in pots or trays and kept in a warm and bright location. The seedlings should be transplanted to their final location once they are large enough to handle.
Division of Roots
The diversity-leaved alumroot can also be propagated through root division. This method can be done in the spring or in the fall. The plant should be dug up, and then the roots should be divided into sections with a sharp knife or garden scissors. Each section should have healthy leaves and roots. The sections can then be replanted in their final location.
Leaf Cuttings
Propagation through leaf cuttings is another option for Heuchera micrantha Dougl. ex Lindl. var. diversifolia. This method is best done in the spring. A healthy leaf should be cut from an established plant and then divided into sections. Each section should have a healthy vein. The sections can then be planted in a suitable potting mix and kept moist until the roots develop. Once the roots have established, the new plants can be moved to their final location.
Disease Management
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela is typically a hardy plant that is not highly susceptible to disease. However, there are some common diseases that may affect this plant and need to be managed properly to prevent damage:
- Crown rot: This is a fungal disease that infects the base of the plant, causing the leaves to wilt and turn yellow or brown. To manage crown rot, remove infected areas, improve soil drainage, and avoid overwatering the plant.
- Powdery mildew: This is a fungal disease that appears as white powdery spots on the leaves and stems. To manage powdery mildew, apply fungicides early in the season, water plants from below, and thin overcrowded foliage to improve air circulation.
- Leaf spot: This is a fungal disease that appears as circular brownish spots on the leaves. To manage leaf spot, remove infected foliage, control moisture, and avoid overcrowding the plant.
Pest Management
Heuchera micrantha Dougl. ex Lindl. var. diversifolia (Rydb.) Rosendahl, Butters & Lakela is generally not highly susceptible to pests. However, there are some common pests that may cause damage to this plant and need to be managed properly:
- Aphids: These are small insects that suck the sap from the leaves, causing them to wilt and turn yellow. To manage aphids, use insecticidal soap or neem oil, introduce natural predators such as ladybugs or lacewings, and remove heavily infested foliage.
- Spider mites: These are tiny insects that feed on the underside of the leaves, causing them to turn yellow and mottled-looking. To manage spider mites, use insecticidal soap or neem oil, mist plants frequently to increase humidity, and remove heavily infested foliage.
