Siberian Squill Scilla siberica
ABOUT
Scilla siberica, also known as Siberian squill, is a charming spring-blooming plant that boasts vibrant blue flowers. Each blossom is bell-shaped with six petals, gracefully hanging down from their stalks like a delicate pendant. The petals have a slightly reflexed shape, curling outward from the center, and this creates a subtle star-like silhouette. The blue of the flowers is quite striking-often described as a rich, true blue or even a vivid sky blue, and it is not uncommon for the petal tips to have a fainter hue or appear almost translucent. The flowers of Siberian squill emerge from bulbs and are borne on slender, willowy stems that add to their ethereal quality. Each stem typically carries one to three flowers, but sometimes they can have more. Supporting the blossoms are narrow, glossy green leaves that are strap-shaped with a length that complements the flowers. The foliage forms an attractive tuft at the base of the stems. The overall impression of the plant is one of delicacy and vibrant color, which stands out in stark contrast against the brown tones of its typical early-spring background. Because of its bright color and early flowering time, Siberian squill is often used to create sweeps of blue in woodlands, lawns, and garden borders where it can naturalize and form beautiful carpets of color.

WaterSiberian squill prefers consistent moisture during its growing season, especially in the spring. Water these plants when the top inch of soil feels dry to the touch. A good rule of thumb is to provide about 1 inch of water weekly, but be sure to adjust depending on rainfall and temperature, as overwatering can lead to bulb rot. As the foliage begins to die back after flowering, you can reduce watering frequency as the plant goes dormant. During the dormant period, water sparingly, only to keep the soil from completely drying out.
LightSiberian squill thrives in partial to full sunlight. Ideally, they should be planted in a spot that receives morning sun and afternoon shade, especially in regions with hot summers. They can also grow well under deciduous trees where they will receive sunlight before the trees leaf out fully in spring.
TemperatureSiberian squill is cold-hardy and can survive winter temperatures as low as -40 degrees Fahrenheit, making it suitable for many gardens in the United States. The ideal temperature range for active growth is between 60 and 70 degrees Fahrenheit during the day. It's also important to provide a period of cold dormancy, so maintaining temperatures below 50 degrees Fahrenheit in winter is beneficial for flower formation.
PruningPruning is not typically required for Siberian squill as the plant is low-maintenance and tends to naturally die back after flowering. However, if you wish to tidy up the garden, wait until the foliage has yellowed and died down before trimming it off, as premature removal can weaken the bulbs. This usually occurs once annually after the spring bloom.
CleaningAs needed
SoilSiberian Squill thrives in well-draining soil rich in organic matter with a pH range of 5.5 to 7. To create the best soil mix, combine garden soil, peat moss, and perlite or sand in equal parts. Regular addition of compost or well-rotted manure will maintain the soil's fertility and structure.
RepottingSiberian Squill rarely needs repotting as it is typically grown as a bulb which naturalizes outdoors. Indoors, repot only if the bulbs outgrow their container, which is usually every 3-4 years.
Humidity & MistingSiberian Squill is relatively tolerant of different humidity levels but prefers normal to slightly above average humidity. Indoor environments typically offer sufficient humidity for this plant.
Suitable locationsIndoor
Place Siberian Squill in a bright spot with cool temperatures and water moderately.
Outdoor
Plant Siberian Squill bulbs in fall, 3 inches apart, and 2-3 inches deep.

Life cycleScilla siberica, commonly known as Siberian squill, begins its life cycle in the form of a bulb that lies dormant underground throughout the summer. In autumn, as temperatures cool, roots develop and the bulb prepares for growth. During early spring, leaves emerge from the soil, followed by the striking blue, bell-shaped flowers that are characteristic of the plant. After pollination, which can occur via insects such as bees, the flowers develop into small, capsule-like fruits that contain seeds. Once the seeds mature, they are dispersed by various mechanisms, including gravity and water. After the flowering season, the plant's foliage dies back, and the bulb goes into dormancy again until the next growth cycle.
PropogationPropogation time
Spring
Siberian squill is typically propagated through bulb division, a straightforward and effective method for this species. The best time to propagate Siberian squill is in late summer to early fall, after the foliage has died back and the plant is dormant. To propagate, carefully dig up the clusters of bulbs, being cautious not to damage them. Gently separate the bulbs, leaving the small bulbils attached to the primary bulbs. These smaller offshoots will eventually grow into full-sized plants. Replant the bulbs at a depth of about 3 to 4 inches (7.5 to 10 centimeters) with the pointed end facing upwards, spacing them about 3 inches (7.5 centimeters) apart to ensure adequate growing space. Within a year or two, these bulbs will mature and begin blooming, thus multiplying the beauty of Siberian squill in your garden.
