Origin
Potentilla stipularis L. var. groenlandica Sorensen, commonly known as Greenland cinquefoil or Arctic cinquefoil, is a herbaceous plant species from the Potentilla genus. It belongs to the Rosaceae family and has its origins in Greenland, Canada and Alaska. The plant is well adapted to the cold and harsh climate of the Arctic regions.
Common Names
Potentilla stipularis L. var. groenlandica Sorensen is commonly known as Greenland cinquefoil or Arctic cinquefoil. In Greenlandic language, it is called "Silatsiaapak", meaning "plant with five fingers".
General Appearance
Potentilla stipularis L. var. groenlandica Sorensen grows to a height of 5-20 cm, forming small patches. The stems are thin, wiry and covered with short hairs. The leaves are dark green and have a palmate shape, with 5-7 lobes, each lobe resembling a finger of a hand. The leaves are alternate and stipulate. The flowers are small and yellow, with 5 petals. The plant blooms from July to August. The fruits are dry achenes, which are dispersed by wind.
Uses
Potentilla stipularis L. var. groenlandica Sorensen has several uses. The Inuit people of Greenland and Canada have traditionally used the plant for medicinal purposes. The plant has antiseptic and anti-inflammatory properties and has been used to treat various ailments, including infections, wounds, and stomach problems. The plant is also used as a dye, producing a yellow color. In addition, the plant has ornamental value and is used as a ground cover in rock gardens and alpine gardens.
Light Requirements
Potentilla stipularis L. var. groenlandica Sorensen prefers to grow in full sun to partial shade. It can tolerate shade but will have reduced growth and blooms. In areas with high temperatures, partial shade is preferred to protect the plant from sunburn.
Temperature Requirements
The plant can tolerate cold temperatures and can grow in USDA Hardiness Zones 2-7. It can handle temperatures that drop as low as -40°F (-40°C). On the other hand, it prefers temperatures that range from 50-75°F (10-24°C). Temperatures that exceed 80°F (27°C) may cause the plant to wilt and suffer.
Soil Requirements
Potentilla stipularis L. var. groenlandica Sorensen grows well in well-drained soils that are moderately fertile and slightly acidic with a pH that ranges from 5.5-7.5. It can tolerate soils that are dry and rocky or slightly damp. The plant prefers soils that are moist but not waterlogged as it can cause root rot. Adding organic matter to the soil can increase fertility and enhance drainage.
Cultivation methods
Potentilla stipularis L. var. groenlandica Sorensen is a hardy perennial plant that can tolerate various soil types ranging from sandy soils to loamy soils. However, the plant thrives best in slightly acidic, hummus-rich soils. It can grow in both sun and partial shade conditions, but it does best in partial shade conditions.
The plant needs room to spread, so it's recommended to space it at least 1 meter apart when planting. Planting should be done in the spring or fall when the soil temperature is warm enough for the roots to establish themselves.
Watering Needs
Potentilla stipularis L. var. groenlandica Sorensen requires medium to regular watering. It's essential to water the plant when the soil is dry to touch. Watering should be done at the base of the plant to avoid wetting the foliage, which can cause fungal diseases. When watering, ensure the water reaches deep into the roots.
Fertilization
This plant does not require a lot of maintenance and can grow well without fertilization. However, fertilization can help boost growth and improve flowering. It's recommended to use a balanced fertilizer with equal amounts of Nitrogen, Phosphorus, and Potassium. Fertilization should be done in the spring before new growth appears.
Pruning
Potentilla stipularis L. var. groenlandica Sorensen requires little pruning, but it's essential to remove dead or damaged stems regularly. Pruning can also help maintain the plant's shape and improve flowering. It's best to prune the plant in late winter or early spring before new growth appears.
Propagation of Potentilla stipularis L. var. groenlandica Sorensen
Potentilla stipularis L. var. groenlandica Sorensen, commonly known as the Arctic cinquefoil, is a hardy perennial plant that thrives in the arctic tundra and subarctic regions. This plant can be propagated using different methods such as seed propagation, division, or stem cuttings.
Seed propagation
Propagation of Potentilla stipularis L. var. groenlandica Sorensen using seeds is an easy and reliable method. The best time to sow the seeds is in the early spring when the soil is still cold and moist. The seeds need stratification before sowing, which is a process of exposing the seeds to low temperatures to mimic the natural conditions for germination.
The seeds should be sowed in well-draining soil and covered lightly with soil. Water the soil gently and keep it moist until the seedlings emerge, which usually takes about two to three weeks. Once the seedlings are established and have a few sets of true leaves, they can be transplanted into individual containers or directly into the ground.
Division
Division is another method of propagation that is commonly used for Potentilla stipularis L. var. groenlandica Sorensen. This method involves dividing the plant's root ball into several smaller sections, each with its own set of leaves and stems.
Division should take place in the spring or fall when the plant is dormant. To divide the plant, lift it gently from the ground and remove any excess soil from the roots. Using a sharp and clean knife, divide the root ball into several small sections. Each section should have a few set of leaves and stems. Plant each division in well-draining soil and water them thoroughly.
Stem cuttings
Propagation of Potentilla stipularis L. var. groenlandica Sorensen using stem cuttings is also an effective method. This method involves taking cuttings from the plant's stems and rooting them in a suitable rooting medium.
To take stem cuttings, select healthy stems from the plant and cut them to about 6 inches in length. Remove any leaves from the bottom inch of the stem and dip the cut end into a rooting hormone. Plant the stem cuttings in a rooting medium such as perlite, vermiculite, or sand. Keep the soil moist and maintain high humidity levels until the cuttings have rooted, which usually takes about 4-6 weeks. Once the cuttings have rooted, they can be transplanted into individual containers or directly into the ground.
