Snow crocus (Crocus chrysanthus 'Snowbunting')
Crocus chrysanthus 'Snowbunting' offers brilliant white blooms in late winter, signaling the start of spring. This low-maintenance Snow crocus naturalizes beautifully.
Complete Plant Information
Overview
As one of the earliest harbingers of spring, Crocus chrysanthus ‘Snowbunting’ provides vital color when the garden is largely dormant. This cultivar delights gardeners with clear white, cup-like flowers contrasted by a cheerful yellow throat, appearing typically in February or March, often while snow is still on the ground. This early emergence makes it a highly valued addition to any early spring display.
As a robust member of the Snow crocus group, Crocus chrysanthus ‘Snowbunting’ is exceptionally easy to grow and requires low maintenance once established. It readily naturalizes, spreading slowly through offsets and self-seeding to form increasingly impressive drifts over successive years. Planting these bulbs offers a spectacular, low-effort return on investment for late winter cheer.
These small bulbs thrive in sunny spots that dry out adequately in summer, making them perfect partners for deciduous trees or blending seamlessly into lawn areas. The foliage of Crocus chrysanthus ‘Snowbunting’ must be left untouched post-bloom to ensure energy storage for next year’s performance.

How to Grow
Plant Crocus chrysanthus ‘Snowbunting’ corms in the autumn, generally between September and November, depending on your local frost schedule. Choose a location that receives full sun early in the season, although partial afternoon shade is tolerated once overhead trees leaf out. The key to success is excellent drainage; these bulbs perform poorly in heavy, waterlogged clay soils. If drainage is questionable, amend the soil liberally with sand or grit before planting the corms 3 to 4 inches deep and spaced 3 to 6 inches apart.
Watering needs are generally minimal once established, requiring medium moisture during their active growing phase in late winter and early spring. Fertilization is usually unnecessary if the soil is reasonably fertile. The most critical care note involves the foliage: after the stunning white blooms fade, do not mow the lawn or cut back the leaves. Allow the leaves of the Snow crocus to yellow and naturally die back completely (about six weeks) so the bulb can recharge for the following year.
Crocus chrysanthus ‘Snowbunting’ is excellent for naturalizing, meaning it is perfect for planting freely within lawns, under high tree canopies, or throughout informal woodland settings. As the plants go dormant by late spring, they fit perfectly beneath spring ephemeral wildflowers or perennials that awaken later in the season.
Landscape Uses
The primary role of Crocus chrysanthus ‘Snowbunting’ is to deliver immediate, vibrant color to the landscape when little else is stirring. Their low stature and early bloom make them superb for mass planting in naturalized drifts across open lawns or sunny woodland edges, creating spectacular sweeps of white punctuated by yellow centers. This habit ensures they are seen and enjoyed up close before summer growth obscures them.
Beyond lawns, consider grouping these bulbs in rock gardens where gritty, well-drained soil mimics their preferred native habitat. They also serve as excellent border edging along walkways or placed directly in front of evergreen shrubs, providing necessary contrast against darker winter backgrounds. The reliability and ease of multiplication ensure that the impact of Crocus chrysanthus ‘Snowbunting’ only increases with time.

Flower Qualities
- Showy
Noteworthy Characteristics
Crocus chrysanthus species originate from areas spanning Greece to Turkey and are often called golden crocus due to the typical yellow hues of the species, though ‘Snowbunting’ is distinctly white. This specific cultivar, introduced in 1914 and named after the largely white-feathered northern bird, displays clear white flowers enhanced by lilac feathering on the exterior, a yellow throat, and bright yellow-orange anthers. It typically beats the later Dutch hybrids to bloom, often flowering near the same time as snowdrops.
Tolerances
- Deer
- Black Walnut
Potential Problems
Crocus chrysanthus ‘Snowbunting’ generally remains free from serious insect or disease issues, contributing to its low-maintenance profile. The primary challenge comes from foraging rodents; squirrels, mice, and voles frequently dig up and consume newly planted corms, viewing them as an easy winter snack. To mitigate this, plant corms deeper than usual (slightly over 4 inches) or use protective corm cages upon initial autumn planting. It is worth noting that while rodents can be an issue, deer typically leave crocus untouched, and the plant proves tolerant of root competition from black walnut trees.
Frequently Asked Questions
What hardiness zones is Snow crocus suitable for?
Crocus chrysanthus ‘Snowbunting’ is reliably hardy across USDA Zones 3 through 8, making it widely adaptable in many temperate climates.
When does Snow crocus bloom?
This early blooming bulb typically flowers intensely from February through March, often providing the very first color in the garden landscape.
How large does Crocus chrysanthus ‘Snowbunting’ grow?
This diminutive perennial remains very close to the ground, reaching a maximum height between 0.25 and 0.5 feet, with a similar spread.
What sun exposure does Crocus chrysanthus ‘Snowbunting’ need?
These early bloomers prefer full sun to ensure maximum flower production but can tolerate light shade, especially from deciduous trees that leaf out later in the spring.
Conclusion
The beauty of Crocus chrysanthus ‘Snowbunting’ lies in its resilience and its commitment to early life; it reliably announces the return of spring with its crisp white flowers. This low-maintenance Snow crocus is easy to naturalize, creating drifts that improve yearly with minimal effort required from the gardener. Before the first hard frost arrives, plan to incorporate these corms into sunny lawn areas or well-drained borders within USDA Zones 3-8.
Companion Planting
Selecting appropriate companions ensures your early spring display remains visually appealing throughout the season. Because the foliage of Crocus chrysanthus ‘Snowbunting’ yellows and disappears by late spring, pair it with plants that emerge later. Consider planting alongside species like Erythronium (Trout Lily), which share similar moisture and light requirements but emerge later, or beneath early-blooming daffodils (Narcissus) which will take over the visual show once the crocus fades.
Propagation Tips
One of the greatest joys of growing Crocus chrysanthus ‘Snowbunting’ is its ability to naturalize, but you can also actively propagate new clumps through division. When the plant is fully dormant (mid-summer, after the foliage has fully yellowed), carefully dig up the clumps of corms. You will notice small offsets or bulblets attached to the larger established corm. Gently separate these smaller bulblets from the mother corm. Replant the offsets immediately at the recommended depth; they may take one or two seasons to reach flowering size but will contribute to future large drifts of this beautiful Snow crocus.
