Origin
Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark, commonly known as sharp-lobed hepatica, is a plant species that belongs to the buttercup family (Ranunculaceae). This plant is native to eastern North American, specifically, the regions ranging from Manitoba down to Texas, and from the East coast to the Great Lakes.
Common Names
Sharp-lobed hepatica is also known by other names such as liverleaf, liverwort, and squirrel cups, which are most commonly used by gardeners and wildflower enthusiasts. The common name "hepatica" comes from the Greek word "hepar," which means "liver," due to the liver-like shape of its leaves.
Uses
The plant has been traditionally used by native people in North America for medicinal purposes. The leaves of sharp-lobed hepatica were believed to be beneficial for treating liver and stomach ailments, while the roots were used to make tea to alleviate coughs and cold symptoms. Today, the plant is not widely used for medicinal purposes.
General Appearance
Sharp-lobed hepatica is a herbaceous perennial plant that grows to a height of 4-6 inches. The plant features small, leathery, three-lobed leaves that are evergreen and sometimes mottled. In the early spring, sharp-lobed hepatica produces flowers that are pink, purple, lavender, or white, and appear on leafless stems. The flowers have a diameter of about 1 inch and their sepals are hairy. The plant often grows in clusters and prefers moist, well-drained soil that is rich in organic matter and slightly acidic.
Growth Conditions for Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark
As a shade-loving plant, Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark typically grows well under partial to full shade. Direct sunlight can be harmful to the plant's growth and survival. It thrives in cool to moderate climates and is often found in woodland areas.
Light
The ideal light conditions for Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark are partial to full shade. The plant can tolerate some morning sun, but direct sunlight should be avoided. Too much sun exposure can cause the leaves to become scorched and dry out.
Temperature
The temperature range for Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark is between 10°C-20°C (50°F-68°F). The plant prefers a cool environment and does not do well in hot and humid conditions. During the winter, the plant is cold hardy and can survive temperatures as low as -30°C (-22°F).
Soil Requirements
The plant grows best in well-drained, humus-rich, and slightly acidic soil. Soil that is too heavy and clay-like or too sandy may not be suitable for the plant's growth. Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark prefers soil that is moist but not waterlogged. It is recommended to fertilize the soil before planting the seeds or seedlings to provide the necessary nutrients for the plant's growth.
Cultivation Methods
Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark, commonly known as sharplobe hepatica, prefers a partially shaded spot with well-draining soil that is rich in organic matter. The plant thrives in cool and moist conditions, so choosing a location with plenty of filtered sunlight will promote healthy growth. Sharplobe hepatica can be grown in both containers and garden beds, making it a versatile plant for cultivation.
Watering Needs
Sharplobe hepatica has a shallow root system, so it requires frequent watering in order to maintain optimal hydration levels. It is recommended to water the plant regularly, but avoid overwatering as this can cause root rot. It is important to note that in periods of rain, watering may not be necessary, so be sure to check the soil's moisture level before watering the plant.
Fertilization
Sharplobe hepatica benefits from fertilizing in early spring before the leaves emerge. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium is ideal for promoting healthy growth. During the blooming period, it is recommended to use a low-nitrogen fertilizer to encourage the plant to produce more flowers.
Pruning
Sharplobe hepatica does not require extensive pruning, but deadheading spent blooms and removing diseased or damaged leaves can promote healthy growth. Deadheading can also encourage the plant to produce more flowers throughout the blooming period. It is important to use sharp pruning tools when working with the plant, as sharplobe hepatica is susceptible to disease and infections that can be transmitted through dull blades.
Propagation of Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark
The propagation of Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark can be achieved through both sexual and asexual means.
Propagation through seeds
Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark produces seeds in mature capsules. The seeds should be collected once the capsules turn brown and dry. They can then be sown in a mixture of soil, sand, and peat moss in a propagator or a sheltered area, either in the fall or spring.
The seeds require a period of cold stratification for 60-90 days before they germinate. They prefer damp soil and a partially shaded area. Once they germinate, they can be transplanted into individual pots and then into larger containers or outside in the garden if the plant is mature enough.
Propagation through division
Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark can also be propagated through division. This is done by dividing the mature clumps in late summer or early fall, or after they finish flowering in the spring.
The clumps can be carefully lifted from the ground and divided into smaller sections, ensuring that each division has at least one bud and a portion of the root system. The divisions should then be planted in suitable pots or directly in the garden in a partially shaded area with moist soil.
Propagation of Hepatica nobilis Schreb. var. acuta (Pursh) Steyermark can be moderately challenging, but it is well worth the effort to grow this beautiful plant in your garden.
