Alpine Squill Scilla bifolia
ABOUT
The plant known as two-leaf squill or alpine squill, features a striking and delicate appearance with a lush, green base and vibrant floral displays. It emerges with two leaves that are narrow and elongated, providing a rich, verdant backdrop to its blossoms. The flowers themselves are a captivating shade of blue, sometimes veering towards purple or even a blue-tinged white. Each individual flower is bell-shaped, hanging daintily from the stem, and grouped in clusters that form an attractive display. The petals of these blossoms are typically upward facing, and their tips can be slightly recurved, adding to their delicate appearance. This plant thrives in the cooler times of the year, bringing lively color to gardens and natural areas before many other plants have begun to wake from their winter dormancy. The overall effect of this plant is one of gentle beauty, with its soothing colors and elegant form drawing the eye and bringing early interest to the areas where it is grown.

WaterFor Siberian Squill, watering should be moderate, aiming to keep the soil consistently moist but not soggy. During the active growing season, typically in the spring, water the plant thoroughly once a week with approximately 1 gallon of water. When the plant goes dormant in the summer, reduce watering to encourage this natural cycle. If rainfall is sufficient, additional watering may not be necessary. However, if the weather is particularly dry, water the plant to prevent the soil from completely drying out. It is important to avoid overwatering, as this can lead to root rot.
LightSiberian Squill thrives best in partial to full sunlight. It can tolerate light shade, especially in hotter climates, but ideally, it should receive at least four to six hours of sunlight each day. The best spot for the plant would be an area that gets morning sunlight and afternoon shade or dappled sunlight throughout the day, especially if planted under deciduous trees that provide filtered light.
TemperatureSiberian Squill is a hardy plant that prefers cooler temperatures and can tolerate a temperature range from as low as 20°F to around 75°F. The ideal temperature conditions are between 50°F and 65°F, which are typical in spring in many temperate regions. While the plant can survive occasional dips below 20°F, it's crucial that the ground is not frozen solid, as the bulbs need to be able to take up water.
PruningPruning is not typically necessary for Siberian Squill, as the plant is low-maintenance in this regard. Allow the foliage to die back naturally after flowering to enable the plant to store energy for the next year. If you must tidy up the garden, prune only the dead or yellowing leaves once they have turned brown. The best time for any clean-up would be late spring or early summer after the leaves have yellowed.
CleaningNot needed
SoilAlpine Squill thrives in well-draining soil mixed with plenty of organic matter like compost or leaf mold. A good recipe for soil mix would be one part garden soil, one part compost, and one part sharp sand or perlite to aid drainage. The ideal pH range for Alpine Squill is slightly acidic to neutral, around 6.0 to 7.0.
RepottingAlpine Squill, being a bulbous plant, does not require frequent repotting; it is best repotted only when the bulbs have become overcrowded, typically every 3-4 years after flowering has finished in spring.
Humidity & MistingAlpine Squill prefers moderate humidity but is quite adaptable and can tolerate the humidity levels typically found in most homes without any special modifications.
Suitable locationsIndoor
Place Alpine Squill in bright, indirect light inside, ensuring cool temperatures.
Outdoor
Plant Alpine Squill in partial shade outdoors with well-draining soil.

Life cycleScilla bifolia, commonly known as Alpine squill or Twinleaf squill, begins its life as a bulb, which lies dormant underground during the summer and emerges in late winter or early spring. The plant sprouts slender, basal leaves and produces small, star-shaped blue to purple flowers on leafless stalks during its flowering stage, typically from March to April. After pollination, the flowers develop into capsule-like fruits, which release seeds once they mature. The seeds then disperse, often aided by ants through a process known as myrmecochory, and can give rise to new bulbs if they land in a suitable environment. The above-ground parts of the plant die back after seed dispersal, and the bulb enters a period of dormancy to conserve resources. The cycle recommences the following spring when soil temperatures increase and after the bulb has been chilled during the winter, which is necessary for its growth cycle.
PropogationPropogation time
Spring
The most popular method for propagating the common Scilla bifolia, known as the Alpine squill, is through bulb division. This method is best performed in the fall, after the foliage has died back. Gardeners gently dig up the bulbs, taking care not to damage them, and carefully separate the smaller bulbs from the main bulb. These offsets are then planted immediately at a depth of about 3 inches (approximately 7.5 centimeters) and spaced about 4 inches (about 10 centimeters) apart, in well-draining soil with good access to sunlight. The new plants will typically flower in the following spring, continuing the cycle of growth.
