The leaves of the plant can also be brewed to make a tea that is used to treat sore throats and respiratory infections.
General appearance
The firecracker plant has a compact and bushy growth habit and can grow up to 12-18 inches tall and 12-15 inches wide. The leaves are evergreen and typically have a rounded shape with deep lobes and serrated edges. The foliage comes in various shades of green, purple, and silver, adding texture and color to the plant.
The flowers of the plant grow on long stalks and bloom from late spring to early summer. The flowers are tubular in shape and come in various shades of red, orange, and pink. The flowers attract hummingbirds and butterflies, making it a great addition to a pollinator garden.
Light Requirements
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl do best when exposed to partial shade. This species is not adapted to grow under full sun exposure and needs some protection from its intense rays to have thriving growth. When grown in areas with high sun exposure, the leaves of the plant may turn yellow and wilt.
Temperature Preferences
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl can tolerate a wide range of temperatures, but thrive in areas with mild temperatures. This plant species grows best in temperatures averaging between 65 to 75 degrees Fahrenheit during the day and 45 to 55 degrees Fahrenheit at night. Extreme temperatures cause stress on the plant that may lead to death and slower growth rates.
Soil Requirements
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl prefers well-drained soils. Poorly drained soils tend to restrict the roots' growth causing poor nutrient absorption, root rot, and ultimately, stunted growth. The soil pH for this plant should be slightly acidic, ideally between 6.0 and 7.0. The addition of organic matter such as compost, manure, or mulch is ideal as it helps to keep the soil well-aerated and aids in moisture retention.
Cultivation Methods
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl prefers well-drained soil that is rich in organic matter. The plant can be propagated by seed or division. Plant the seeds in early spring, and they will germinate in three to four weeks. Alternatively, divide the plant in the spring or fall by carefully digging it up and separating the roots into several small clumps. Place each clump in the prepared soil, ensuring the crown is at ground level. The plant should receive partial to full sun exposure and is tolerant of drought, making it ideal for xeriscaping.
Watering Needs
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl needs moderate watering, especially during hot and dry periods. It is essential to avoid overwatering and maintaining damp soil. One way to determine if the plant needs watering is by sticking a finger into the soil. If it feels dry to a depth of two inches, it is time to water. However, if the soil is still moist, watering can wait for a day or two. Consistent moisture in the soil will ensure consistent flowering throughout the growing season.
Fertilization
Fertilization is not necessary for Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl, as it can grow well on its own. However, applying a slow-release granular fertilizer in early spring or late fall may help improve soil quality and encourage growth. Ensure that the fertilizer is spread evenly, at least six inches away from the base of the plant, to avoid damaging the roots. Alternatively, adding a layer of compost over the soil in the fall will not only provide nutrients but reduce weed growth and maintain moisture.
Pruning
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl does not require extensive pruning. However, removing spent flowers can improve its appearance and prolong blooming. Cut off the flower stems at their base, just above the leaves. This deadheading method can also increase airflow around the plant, minimizing the risk of disease and pest infestation. In the early spring, removing any dead or damaged leaves from the previous season will encourage new growth and improve overall plant health.
Propagation of Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl, commonly known as coral bells, is a perennial plant that is grown for its attractive foliage and delicate flowers. It is native to Mexico and the southwestern United States and is relatively easy to propagate through several methods.
Seed Propagation
The easiest way to propagate Heuchera sanguinea var. pulchra is through seed propagation. The plant produces small, black seeds that can be collected after the flowers have faded. The seeds should be sown in a well-drained soil mix and should be kept moist until they germinate. Germination can take up to 2-3 weeks. Once the seedlings have grown large enough to handle, they can be transplanted into individual pots or directly into the garden.
Division
Another propagation method for Heuchera sanguinea var. pulchra is division. This involves digging up an established plant, separating the clumps of stems and roots, and replanting them in individual pots or directly into the garden. The best time to do this is in the spring, just as new growth is starting.
Cuttings
Heuchera sanguinea var. pulchra can also be propagated through cuttings. This involves taking stem cuttings from an established plant, dipping them in rooting hormone, and planting them in a well-drained soil mix. The cuttings should be kept moist and warm until they take root. This method is best done in the spring or early summer when the plant is actively growing.
Regardless of the propagation method used, it is important to provide Heuchera sanguinea var. pulchra with consistent moisture and well-drained soil in order for it to thrive.
Disease and Pest Management for Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl
Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl, commonly known as coral bells, is a herbaceous perennial that is often grown for its decorative foliage and clusters of bright red or pink flowers. However, like all plants, it is susceptible to a variety of diseases and pests that can impact its health and appearance. Here are some common issues that may affect coral bells and ways to manage them.
Diseases
Fungal Leaf Spot: This is a common fungal disease that can cause circular brown spots on the foliage of coral bells. To prevent this disease, avoid overhead watering, provide adequate spacing between plants to promote air circulation, and water in the morning so that the foliage has time to dry before nightfall. If fungal leaf spot does occur, remove affected foliage and treat with a fungicide containing copper.
Powdery Mildew: Powdery mildew is a fungal disease that can appear as a white, powdery coating on the leaves and stems of coral bells. To prevent powdery mildew, avoid overhead watering and provide good air circulation around the plant. If powdery mildew is present, remove affected foliage and treat with a fungicide containing sulfur.
Root Rot: Root rot is a fungal disease that affects the roots of plants and can cause wilting and yellowing of leaves. To prevent root rot, make sure the soil around coral bells is well-draining and do not overwater. If root rot is suspected, remove affected plants and improve soil drainage before replanting.
Pests
Spider Mites: Spider mites are tiny pests that can cause yellowing, stippling, and webbing on the leaves of coral bells. To prevent spider mites, avoid over-fertilizing and keep the plants well-watered. If spider mites are present, remove affected foliage and treat with an insecticidal soap or horticultural oil.
Slugs and Snails: Slugs and snails can cause damage to the foliage of coral bells, leaving behind large holes and ragged edges. To prevent slugs and snails, keep the area around the plants free of debris and avoid over-watering. If slugs and snails are present, handpick them off the plants or use a bait containing iron phosphate.
By taking preventative measures and promptly addressing any issues that arise, you can keep your Heuchera sanguinea Engelm. var. pulchra (Rydb.) Rosendahl healthy and looking its best.
