Ledebouria socialisSilver squill, Wood Hyacinth
Silver Squill requires bright light with 3 to 4 hours a day of direct sunlight.
Outdoor plants can withstand winter temperatures down to 30°F (-1°C).
Once established, water needs are minimal. Allow the top inch (2.5 cm) to dry out before irrigating in spring and summer. Once winter has arrived, the plant is in its rest phase (dormancy) and watering should be cut in half.
During the growth season, apply liquid fertilizer once per month.
