However, some indigenous American tribes have used the plant to treat minor ailments such as coughs, skin irritation, and sore throats. The plant is also used as an ornamental in some garden designs due to its delicate white flowers and attractive foliage.
General Appearance
The smallflower brookweed is a low-growing perennial herb that can reach up to 50 cm in height. Its stem is erect, smooth, and green in color, and its leaves are alternate, elliptic or oblong, and slightly toothed. The flowers of the plant are small, white, and star-shaped, with five petals and a greenish-yellow center. The flowers bloom from June to September and are followed by small, capsule-like fruits.

Light Requirements
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén typically grows best in areas with full sunlight. It requires at least 6 to 8 hours of direct sunlight daily to grow optimally.
Temperature Range
This plant species is able to thrive in both cool and warm temperatures, with an optimal range between 65°F and 75°F (18°C to 24°C). Temperatures below 60°F (15°C) can negatively affect plant growth, while high temperatures above 80°F (27°C) can cause heat stress.
Soil Requirements
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén grows well in a variety of soils, but prefers moist soil that remains consistently damp. It prefers neutral to slightly alkaline soil pH of between 6.5 to 8.0. It is also tolerant of soils that are occasionally flooded with salt water.
Nutrient Requirements
This plant has low to moderate nutrient requirements and thrives in soils with adequate levels of nitrogen, phosphorus, and potassium. To promote optimal growth, it is recommended to apply a balanced fertilizer regularly during the growing season.
Cultivation
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén is a relatively easy plant to cultivate in both indoor and outdoor environments. It can be propagated from seeds or cuttings and prefers moist soil and partial shade. Given the right growing conditions, the plant can quickly reach a height of up to 12 inches.
Watering Needs
This plant thrives on a consistent moisture level and requires frequent watering during the growing season. During hot and dry weather, the soil should never be allowed to dry out, and watering should be done early in the morning or late in the evening to avoid water evaporation.
Fertilization
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén is a light feeder, and applying a general-purpose fertilizer once in early spring and again in mid-summer may be sufficient to keep the plant healthy and thriving. The fertilizer should be applied according to the manufacturer's instructions, and the soil should be well watered after feeding.
Pruning
This plant does not require regular pruning, but removing yellow or dead leaves and stems can help prevent diseases while promoting healthy growth. Pruning can be done throughout the year, but it is best to avoid pruning during the winter dormant season. When pruning, use sharp and clean tools to make clean cuts and avoid damaging the plant.
Propagation of Samolus valerandi L. ssp. parviflorus (Raf.) Hultén
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén is a semi-aquatic and perennial plant that is native to North America and Europe. It is commonly known as smallflower brookweed or water pimpernel. The plant can grow up to 10-20 cm tall and has dark-green leaves with tiny white flowers that bloom in the summer.
Propagation Methods
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén can be propagated through several methods, including:
Seed Propagation
The seeds of Samolus valerandi L. ssp. parviflorus (Raf.) Hultén can be sown directly on the soil surface in a tray or pot filled with a mixture of sand and peat. The tray or pot should be kept moist and be placed in a well-lit area with a temperature of around 18-21°C. The seeds will germinate within 14-21 days, and the seedlings can be transplanted to individual pots once they have developed their first true leaves.
Cuttings Propagation
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén can also be propagated through stem cuttings. Using a clean and sharp knife, cut a stem that is around 5-10 cm long with some leaves. Remove the leaves from the lower part of the cutting and dip the cut end into rooting hormone powder. Plant the cutting into a pot filled with a mixture of sand and peat. Keep the pot moist and place it in a well-lit area with a temperature of around 18-21°C until the rooting has occurred. Once the roots have developed, the plant can be transplanted into a larger pot or in the garden.
Division Propagation
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén can also be propagated through division. The plant should be dug out, and the roots should be divided into smaller sections. Each section should have a healthy shoot and root system. The divided sections should be planted into pots or the garden in a well-draining soil mixture and kept moist until the plant has established.
In conclusion, Samolus valerandi L. ssp. parviflorus (Raf.) Hultén can be propagated through seed, cutting, and division. Understanding the propagation methods can help you to create new plants and maintain the long-term growth of your existing plants.
Disease Management
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén is generally resistant to many diseases. However, the following are some common diseases that may affect the plant:
- Anthracnose: This is a fungal disease that causes brown or black spots on leaves and stems. To manage this disease, remove and destroy infected plant parts and apply a fungicide.
- Leaf Spot: This is a fungal disease that causes small, dark, and irregular-shaped spots or patches on leaves. To manage this disease, remove and destroy the infected plant parts and apply a fungicide.
- Root Rot: This is a disease caused by fungi that attack the roots of plants, resulting in their decay. To manage this disease, avoid overwatering the plant and improve the soil's drainage. Apply a fungicide to infected plants.
Pest Management
Samolus valerandi L. ssp. parviflorus (Raf.) Hultén is generally pest-resistant. However, the following are some common pests that may affect the plant:
- Aphids: These are small insects that suck the sap from the plant's foliage. To manage this pest, apply insecticidal soap, neem oil or horticultural oil.
- Spider Mites: These are tiny pests that produce spider-like webs on the plant's leaves. They suck sap from the leaves, leading to stunted growth and yellowing of the leaves.To manage this pest, apply insecticidal soap, neem oil or horticultural oil.
- Whiteflies: These are small, winged insects that feed on the plant's leaves, causing them to turn yellow and curl. To manage this pest, apply insecticidal soap, neem oil, or horticultural oil.
