The White Blood Lily (Scadoxus multiflorus subsp. katherinae) is a bulbous plant known for its striking floral display. It can enhance various garden settings or indoor plant collections, offering an exotic and visually appealing specimen.
Understanding the White Blood Lily
The White Blood Lily (Scadoxus multiflorus subsp. katherinae) is named for its striking white, spherical flower clusters. Native to tropical and subtropical Africa, it thrives in shaded, humid environments. Its distinctive inflorescence, resembling a paint brush, typically emerges before the broad, wavy-edged leaves, which can reach lengths of up to 18 inches, providing a lush, tropical aesthetic even when not in bloom.
Comprehensive Planting and Care
Plant White Blood Lily bulbs with their tops just at or slightly above the soil surface, leaving a small portion exposed. For container planting, a 6 to 8-inch pot is suitable. Use a well-draining, rich soil mix, such as a blend of organic compost, sand, and well-rotted animal manure in a 1:4:1 ratio, to ensure proper drainage and nutrient supply.
White Blood Lilies thrive in bright, indirect light or partial shade, similar to their natural habitat under tree canopies. Direct, intense sunlight can scorch their leaves, so a sheltered location is beneficial. During the active growing season (spring through summer), keep the soil consistently moist but not waterlogged. Excellent drainage is crucial to prevent bulb rot from overwatering.
These tropical plants prefer average room temperatures, between 65-80°F (18-27°C), tolerating a minimum of 50°F (10°C). Protect them from frost and cold drafts. Typical indoor humidity levels are usually sufficient, though higher humidity can be beneficial. During active growth, fertilize every one to two weeks with a half-strength, high-phosphorus, water-soluble fertilizer.
As autumn approaches and flowering concludes, the plant enters dormancy. Gradually reduce watering, allowing foliage to die back naturally. During this winter dormancy, the bulb requires minimal water, just enough to prevent drying out. If grown in containers, move them to a cool, dry, frost-free location, ideally above 50°F (10°C).
Propagating White Blood Lilies
White Blood Lilies are best propagated by dividing offsets, which are small bulbs that form around the parent. Separate these offsets carefully from the main bulb, typically after the flowering period or during dormancy. Gently remove the parent plant from its pot and detach the offsets, ensuring each has some roots.
Plant the separated offsets in individual pots using a well-draining, rich soil mix, positioning them so the tip of the small bulb is just visible above the soil line. Keep the soil lightly moist; new growth should emerge as the plant exits dormancy. While seed propagation is possible, it is a slower process, with seedlings taking approximately three years to flower.
Addressing Common Problems
While generally robust, White Blood Lilies can face issues. Lack of blooms often stems from insufficient light during the growing season or improper dormancy care. Provide bright, indirect light and a distinct, dry dormant period to encourage flowering.
Yellowing leaves may indicate overwatering, leading to root rot, or a nutrient deficiency. Adjust watering to allow the soil to dry slightly between waterings and provide regular fertilization during active growth. Though generally pest-resistant, spider mites or mealybugs can occur, managed with horticultural oil or insecticidal soap. Fungal issues, like root rot, are primarily caused by consistently waterlogged soil, highlighting the need for well-draining potting mix and careful watering.
Is White Blood Lily Toxic?
Yes, the White Blood Lily (Scadoxus multiflorus subsp. katherinae) is toxic. All parts, especially the bulbs, contain alkaloids that can cause adverse reactions if ingested. Symptoms include vomiting, diarrhea, and abdominal pain. Due to its toxicity, handle the plant with caution and keep it out of reach of children and pets. Wearing gloves when handling is a sensible precaution.
