It can be found in eastern Canada and the United States, ranging from Newfoundland and Labrador to Florida and westward to Minnesota and Texas.
Common Names
Aside from its scientific name, Ranunculus abortivus L. ssp. acrolasius is also commonly referred to as the small-flowered buttercup, little-flowered buttercup, or the littleleaf buttercup.
Uses
Ranunculus abortivus L. ssp. acrolasius has several uses in traditional medicine. The Native American Cherokee tribe used the plant as a remedy for headaches and toothaches. It was also used as a poultice to treat ulcers and sore eyes. In modern times, the plant is also used as a remedy for stomach cramps and digestive ailments, as well as a natural diuretic.
General Appearance
Ranunculus abortivus L. ssp. acrolasius typically grows to a height of 10-60cm and can spread up to 30cm wide. It has small yellow flowers that bloom from April to July. The leaves are deeply lobed and are arranged in a rosette at the base of the plant. The stem is slender and hairy, with alternative leaves that are smaller and less divided than the basal leaves. The plant prefers to grow in damp areas such as meadows, stream banks, and woodland edges.
Growth Conditions for Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
Light Requirements: Ranunculus abortivus L. ssp. acrolasius typically grow in areas that receive full sunlight or partial sun exposure. They can tolerate some shade but too much of it can seriously hinder their growth and flowering ability. Therefore, it is advisable to plant them in a location that receives approximately 6-8 hours of direct sunlight.
Temperature Requirements: These plants thrive in environments that are cool and moderately moist. The ideal temperature range for Ranunculus abortivus L. ssp. acrolasius is between 50-60°F (10-15°C). They can survive in temperatures that are slightly lower or higher than this range, but very hot and dry conditions can lead to poor growth and early death of the plant.
Soil Requirements: Ranunculus abortivus L. ssp. acrolasius prefer well-drained, moisture-retaining soils that are rich in nutrients. They can grow in a range of soil types, including sandy, loamy, and clay soils. However, they perform best in deep, loamy soils that are slightly acidic (pH between 6 and 7). Additionally, it is advisable to ensure that the soil is adequately aerated to prevent waterlogging, which can cause the roots to rot.
Cultivation methods for Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
The Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve plant species is not suitable for growing in areas with extremely hot temperatures. The best time to grow the plant is during the fall and spring seasons. The plant prefers a soil that is well-drained, loamy, and moist, with a pH range of 6.5 to 7.5. The plant should be grown in a shaded environment, as exposure to direct sunlight can cause scorching of the leaves.
Watering needs for Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
The Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve plant should be watered regularly, especially during dry seasons. The plant needs to be watered deeply to encourage deep root growth. Avoid overwatering the plant as it can lead to the accumulation of moisture, causing root rot.
Fertilization for Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
The Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve plant should be fertilized regularly to encourage healthy growth and flowering. A balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium should be used. The fertilizer should be applied only during the growing season, and it should be applied in small amounts to avoid fertilizer burn.
Pruning for Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
When the Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve plant has finished flowering, the stems and leaves should be cut back to the soil level. Pruning the plant encourages new growth and better flowering in the next growing season. Deadheading, the removal of spent flower heads, should also be done regularly to keep the plant tidy and to encourage new flowers to grow.
Propagation of Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve
Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve, commonly known as little leaf buttercup, is a flowering plant found in the eastern United States and Canada. It is a herbaceous perennial plant that typically grows up to 20-40 cm tall. The plant produces small yellow flowers which bloom from April to June.
Propagation of Ranunculus abortivus can be done by seeds or vegetative methods. The following are the propagation methods:
Propagation by Seeds
Ranunculus abortivus can be propagated by seeds which can be sown directly into the soil. The seeds must be cleaned and stratified for 3-4 weeks before planting. Stratification can be done by keeping the seeds in moist vermiculite at a temperature of 4°C in a refrigerator. After stratification, the seeds can be planted in well-draining soil in a sunny to partially shaded location. The seeds will germinate in 2-3 weeks.
Propagation by Division
Propagation by division is also a commonly used method for Ranunculus abortivus. The plant can be divided into smaller clumps during the spring or fall season. The clumps can be dug up and separated into smaller sections using a sharp knife or garden scissors. Each section must have leaves and roots. The sections can then be replanted in well-draining soil in a sunny to partially shaded location.
Propagation by Rhizomes
Propagation by rhizomes is another method used for Ranunculus abortivus. The plant produces thin underground stems or rhizomes which can be dug up and separated into smaller sections. Each section must have at least one bud or shoot. The sections can then be replanted in well-draining soil in a sunny to partially shaded location.
Propagation of Ranunculus abortivus can be done easily by any of the above methods. The plant is adaptable to different soil types and growing conditions, making it a great addition to any garden or landscape.
Disease Management
Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve is susceptible to various diseases, including fungal and bacterial diseases. Proper disease management practices should be observed to prevent significant yield loss. Below are common diseases that might affect the plant and ways to manage them.
Anthracnose
This fungal disease can affect the leaves, stems, and flowers of Ranunculus abortivus. Symptoms include the formation of round, dark spots on the leaves and stems. Infected plants may wilt and eventually die. To manage anthracnose, remove infected plant parts as soon as possible and avoid watering the plants from above. Applying fungicides may also help manage the disease.
Botrytis Blight
This fungal disease can affect the stems and flowers of Ranunculus abortivus. Symptoms include the formation of grayish mold on the affected plant parts. Infected plants may show signs of wilting and eventually die. To manage Botrytis blight, remove infected plant parts and avoid overhead watering. Applying fungicides can also help prevent the spread of the disease.
Bacterial Blight
This bacterial disease can affect the leaves, stems, and flowers of Ranunculus abortivus. Symptoms include the formation of black, water-soaked spots on the affected plant parts. Infected plants may eventually die. To manage bacterial blight, remove infected plant parts promptly and apply copper-based bactericides.
Pest Management
Ranunculus abortivus L. ssp. acrolasius (Fern.) Kapoor & A.& D. Löve is susceptible to various pests, including insects and mites. Proper pest management practices should be observed to prevent significant yield loss. Below are common pests that might affect the plant and ways to manage them.
Spider Mites
Spider mites can feed on the leaves of Ranunculus abortivus, causing them to dry out and turn yellow. To manage spider mites, remove heavily infested plant parts and apply insecticidal soap or neem oil.
Aphids
Aphids can colonize the leaves and stems of Ranunculus abortivus and suck the sap, causing distorted growth and yellowing. To manage aphids, remove heavily infested plant parts and apply insecticidal soap or neem oil.
Thrips
Thrips can feed on the flowers of Ranunculus abortivus, causing them to become distorted and discolored. To manage thrips, remove heavily infested plant parts and apply insecticidal soap or neem oil.
Overall, preventing disease and pest infestations is the best way to manage them effectively. Maintaining healthy growing conditions and frequently inspecting plants for signs of disease and pests can help identify problems early and prevent significant damage.
