Crow-poison has two main varieties: one with white flowers (variety A) and another with pink flowers (variety B). When selecting seedlings, choose those with healthy green leaves and no signs of pests or diseases. For seeds, opt for plump, firm seeds without any visible damage. Ensure the seedlings are well-rooted and not root-bound. Variety A is known for its delicate white flowers and prefers partial shade, while variety B showcases vibrant pink blooms and thrives in full sun. Consider the growing conditions in your area to select the most suitable variety.

What is Crow-poison (Nothoscordum bivalve)?
What is Crow-poison (Nothoscordum bivalve)
Flower meaning
Crow-poison, scientifically known as Nothoscordum bivalve, is a perennial herbaceous plant native to North and South America. It belongs to the Amaryllidaceae family and is characterized by its grass-like leaves and small white flowers. The flowers have six petals and are star-shaped, adding an elegant touch to gardens. The plant typically blooms in the spring and summer months. Nothoscordum bivalve is commonly found in open fields, meadows, and along roadsides. It produces small, round fruits that contain seeds for reproduction. The plant is relatively easy to grow, requiring well-drained soil and full sunlight. It can tolerate a variety of soil types and is drought-tolerant once established. Nothoscordum bivalve is often used in landscaping for its delicate appearance and low maintenance requirements.
Calendar of Crow-poison (Nothoscordum bivalve)
Calendar
Crow-poison is susceptible to various pests and diseases, including aphids, spider mites, and leaf spot diseases. These pests and diseases can weaken the plant, leading to stunted growth and yellowing of leaves. Aphids are small insects that feed on plant sap, causing distortion of leaves and the transmission of viruses. Spider mites are tiny arachnids that suck plant juices, causing stippling and webbing on leaves. Leaf spot diseases are fungal or bacterial infections that result in dark spots on leaves, affecting photosynthesis. To prevent these issues, regular inspection of the plant for early detection is crucial. Maintaining proper air circulation and avoiding overhead watering can help reduce the risk of fungal diseases. Insecticidal soaps or oils can be used to control aphids and spider mites. Proper sanitation practices, such as removing and destroying infected plant parts, can also aid in disease management.
How to grow Crow-poison (Nothoscordum bivalve)
Watering
The flower language commonly used in America for Crow-poison is: - Rejection - Unhappiness - Misery One typical example is "Rejection," symbolizing the feeling of being turned away or unwanted. This flower language can convey a sense of disappointment or heartache in various situations.
Soil and Fertilizer
Crow-poison thrives in full sun to partial shade, requiring at least 6 hours of direct sunlight daily. It exhibits moderate cold tolerance, surviving in USDA hardiness zones 5 to 9. In terms of heat tolerance, it can withstand high temperatures but may benefit from some shade during intense heatwaves. Crow-poison prefers an optimum temperature range between 60-80°F (15-27°C). During summer, ensure adequate watering to prevent wilting, and in winter, protect from frost by covering or moving indoors. Place Crow-poison in well-draining soil and avoid waterlogging. It is best suited for outdoor gardens, balconies, or patios where it can receive ample sunlight. Crow-poison's strength lies in its ability to thrive in bright, direct sunlight, making it ideal for sunny locations.
Sunlight and Place
For optimal growth, water Crow-poison plants every 7-10 days during the growing season. Ensure the soil is consistently moist but not waterlogged. In winter, reduce watering frequency to every 2-3 weeks to prevent root rot. Check soil humidity by inserting a finger 1-2 inches into the soil; if it feels dry, water the plant. Water thoroughly, allowing excess water to drain out of the pot. Adjust watering frequency based on environmental conditions such as temperature and humidity. Avoid overwatering, as it can lead to root rot and other issues. Proper watering is crucial for the health and vitality of Crow-poison plants.
Advanced Information of Crow-poison (Nothoscordum bivalve)
Pruning
Crow-poison thrives in well-drained sandy or loamy soil with a slightly acidic to neutral pH level between 5.5 and 7.0. It requires a soil rich in organic matter to support its growth. Fertilizers high in phosphorus and potassium are beneficial for Crow-poison, such as a 5-10-10 NPK ratio fertilizer. Fertilizer should be applied in early spring before new growth begins, using a slow-release fertilizer to prevent nutrient leaching. During the growing season, a balanced liquid fertilizer can be applied every 4-6 weeks. Avoid fertilizing in late summer to prevent stimulating new growth that may be damaged by frost. Over-fertilization should be avoided as it can lead to nutrient imbalances and harm the plant.
Planting and Harvest
Crow-poison benefits from regular pruning to maintain its shape, promote new growth, and improve overall plant health. Pruning should be done in late winter or early spring before new growth emerges. Remove dead, damaged, or diseased branches by cutting them back to healthy tissue. Additionally, thin out crowded areas to increase air circulation and light penetration within the plant. After pruning, clean your tools with a disinfectant to prevent the spread of diseases. Dispose of the pruned material properly to avoid any potential contamination. Regular pruning will help Crow-poison thrive and produce more flowers.
Propagation
Crow-poison is best potted in well-draining soil with a pH of 5.5 to 6.5. Ensure the pot has drainage holes to prevent waterlogging, and place it in a location with partial shade. When planting, gently loosen the roots and place the plant at the same depth as it was in the nursery container. Water thoroughly after planting and keep the soil consistently moist but not waterlogged. Repot Crow-poison every 2-3 years in the spring, increasing the pot size by 1-2 inches. If the plant becomes root-bound, gently tease out the roots before repotting.
Pests and Diseases
Crow-poison can be propagated through seeds, division, and cuttings. Seeds should be sown in well-draining soil in early spring. For division, separate the plant into sections with roots attached and replant them. Cuttings can be taken from healthy stems and rooted in a moist growing medium. Leaf cuttings involve taking a leaf and planting it in soil to develop roots. To maximize propagation success, utilize a combination of methods. Harvest seeds when they are mature and dry for sowing.
