• Early Spring Color: Be among the first to enjoy vibrant blooms. The bold, golden-yellow flowers emerge early in the season, providing much-needed color and cheer when little else is flowering, making them a true harbinger of spring.
• Vigorous Naturalizer: These crocus bulbs are known for their ability to multiply and spread over time, creating dense, beautiful drifts and carpets of color that grow more impressive with each passing year.
• Low Maintenance: Once established, crocus care is minimal. These bulbs require very little attention, thriving with basic planting and allowing their foliage to die back naturally after blooming.
• Deer and Rabbit Resistant: Enjoy your beautiful blooms without worry. Mammoth Yellow Crocus are generally resistant to common garden pests like deer and rabbits, ensuring your flowers remain unmunched.
• Attracts Early Pollinators: Provide a vital food source for beneficial insects. These early-blooming flowers attract early pollinators like bees, supporting local ecosystems at the start of the growing season.
• Versatile Landscaping: Perfect for a variety of garden settings. Plant them in lawns, under deciduous trees, along borders, in rock gardens, or for naturalizing in open areas to create stunning visual effects.
• Drought Tolerant: Once established, these crocus bulbs exhibit high drought tolerance, preferring dry conditions during their summer dormancy, which makes them a resilient choice for various climates.

Plant Care & Growing Tips

Successful growth of mammoth yellow crocus bulbs begins with proper planting in the fall. Choose a well-drained site that receives full sun to partial shade. These bulbs prefer a location where they can get at least 6 hours of direct sunlight daily during their growing season. Good drainage is crucial, as soggy soil can lead to rot. If your soil is heavy clay, amend it with organic matter like compost or sand to improve drainage.

Plant corms 3-4 inches deep and 2-3 inches apart, ensuring the pointed end is facing upwards. After placing the bulbs, cover them with soil, firm gently to remove any air pockets, and water once thoroughly. Fall planting, typically 6-8 weeks before the ground freezes, allows the bulbs to establish roots before winter. During the winter, a light layer of mulch can provide protection, but be sure to remove it in early spring as new growth emerges. For ongoing crocus care, allow the foliage to yellow and die back naturally after blooming. This process is essential for the bulb to replenish its energy reserves for the following year’s display. Avoid cutting back green foliage prematurely.

These hardy plants thrive in USDA zones 3-8. They are quite adaptable and can tolerate a range of temperatures, but prefer cooler conditions during their active growth period. Fertilization is generally not required for established crocus, especially if planted in fertile soil. However, if your soil is poor, a light application of a balanced slow-release fertilizer designed for bulbs can be applied in the fall. Pests and diseases are rarely an issue, making this an easy-to-grow plant that delivers stunning results with minimal effort. For the best effect, plant these early spring bulbs in clusters or drifts, allowing them to naturalize and create a breathtaking golden spectacle.

Size & Details

These mammoth yellow crocus bulbs produce cheerful blooms that typically grow 4-6 inches tall, with a spread that easily increases over time as they naturalize. The bulbs are planted in the fall, producing their vibrant golden-yellow flowers in early spring. They are ideal for creating dense patches of color in lawns, borders, and rock gardens. Each bulb will produce multiple flowers, and as a vigorous naturalizer, you can expect the clump to expand significantly over the years, leading to an even more impressive display. The grass-like green foliage provides a lovely backdrop to the bold blooms and then gracefully yellows and fades after the flowering season is complete.

These bulbs are shipped dormant and ready for fall planting, ensuring they are prepared to establish roots and burst forth with color the following spring. The high drought tolerance once established means they are resilient and require less water during their summer dormancy period. Enjoy the enduring beauty and effortless charm of these crocus for many seasons to come.
