Oxytropis foliolosa Hook.
Oxytropis foliolosa Hook. is a low-growing perennial plant that belongs to the Fabaceae or pea family. It is native to the high mountains and alpine regions of western North America, including Alaska, British Columbia, and the Rocky Mountains.
Common Names
Oxytropis foliolosa is commonly known as the Leafy Locoweed, Silky Oxytrope, or Littleleaf Oxytropis.
Uses
The plant has been traditionally used by indigenous people for medicinal purposes. It contains alkaloids that are toxic to livestock, but the plant has also been used by Native Americans for its psychoactive properties, including inducing visions and aiding in communication with spirits. However, it must be noted that the plant is toxic to humans, and caution should be exercised when using it.
General Appearance
Oxytropis foliolosa grows typically up to 6 inches in height, with an extensive root system. The leaves are compound and alternate, with 3-9 pairs of leaflets. The stem is thin and usually covered with silky hairs. The flowers are pink to lavender and are clustered in a raceme, appearing in July and August. The fruit is a narrow seedpod covered in sparse hairs.
Light conditions
Oxytropis foliolosa thrives in full sunlight. It requires at least 6 hours of direct sunlight per day to grow properly. However, excessive sunlight may cause the leaves to turn yellow.
Temperature requirements
This plant prefers cooler temperatures and can tolerate frost. The ideal temperature range for Oxytropis foliolosa to grow and thrive is between 2°C to 16°C. It is important to note that hot and humid weather can negatively impact the growth of this plant.
Soil requirements
Oxytropis foliolosa prefers well-drained, sandy loam soil. The soil should be slightly acidic, with a pH ranging from 5.5 to 6.5. It is important to avoid waterlogged soil as it can cause root rot and damage to the plant. This plant does not tolerate saline or heavy clay soils. Adding organic matter to the soil can enhance its fertility and improve soil structure, promoting growth.
Cultivation Methods
Oxytropis foliolosa Hook. is a hardy perennial plant that grows well in dry, rocky soils. It prefers full sunlight and is not tolerant of shade. The plant can be propagated through both seeds and cuttings, but seed propagation is more common. The seeds should be sowed in the early spring, and the seedlings should be transplanted to their permanent location when they reach a depth of 2-3 inches.
Watering Needs
While Oxytropis foliolosa Hook. is a drought-tolerant plant, it still needs adequate water to thrive. The plant should be watered deeply once a week, allowing the soil to dry out between watering. Overwatering can cause the plant to rot, so it's important not to water it too often.
Fertilization
Oxytropis foliolosa Hook. doesn't require a lot of fertilization, as it's adapted to grow in nutrient-poor soils. However, a small amount of fertilizer can be added to the soil in the early spring to encourage growth. A balanced slow-release fertilizer should be used, and it should be applied according to the manufacturer's instructions.
Pruning
Oxytropis foliolosa Hook. doesn't require much pruning, but dead or damaged branches should be removed in the late spring or early summer. This will encourage healthy growth and keep the plant looking neat and tidy. The plant may also be pinched back in the early summer to encourage more branching and a fuller appearance.
Propagation of Oxytropis foliolosa Hook.
Oxytropis foliolosa Hook. is a perennial herbaceous plant that is native to western North America. It is commonly known as leafy locoweed and is a member of the pea family, Fabaceae. Propagation of this plant can be achieved through various methods, including seed propagation and vegetative propagation.
Seed Propagation
Seed propagation is the most common method used to propagate Oxytropis foliolosa Hook. This plant produces seeds in pods, which dry and split open to release the seeds. The seeds are small and black, and they can be collected in the fall when the pods have dried.
Before planting, the seeds must be stratified to break their dormancy. Stratification can be achieved in a few ways, including leaving the seeds outside to experience natural winter temperatures or refrigerating them for several weeks. Once stratified, the seeds can be planted in the spring in well-draining soil. They should be planted about 1 cm deep and spaced about 30 cm apart.
The seeds will germinate within a few weeks, and the seedlings can be transplanted to their permanent location after the last frost of the season. It is essential to keep the newly planted seedlings watered but not waterlogged.
Vegetative Propagation
Vegetative propagation is another method used to propagate Oxytropis foliolosa Hook. This method involves taking cuttings or dividing the plant's root system.
Cuttings should be taken in the summer from new growth. The cutting should be about 10-15 cm long and stripped of leaves on the lower end. The cutting should be placed in well-draining soil and kept moist. Within a few weeks, the cutting should begin to root and can be transplanted to its permanent location.
The plant's root system can also be divided, though this method should only be performed on mature plants. The plant should be dug up and the root system divided into sections, ensuring that each section has a viable amount of roots. The sections can then be transplanted to their permanent location.
Propagation of Oxytropis foliolosa Hook. can be achieved through both seed and vegetative means. With proper care, the plant will thrive and can be a beautiful addition to any garden or landscape.
