This deciduous perennial grows from corms and is known for its early blooming habit. Crocus tommasinianus produces beautiful tubular flowers with long pointy leaves, adding vibrant colors to gardens in early spring.

Cultivation of Crocus tommasinianus:
Sunlight and Soil: Crocus tommasinianus thrives in full sun or partial shade. It prefers well-drained soil, ranging from poor to fertile. Ensure the soil has good drainage to prevent waterlogging and rot.
Planting: Plant Crocus tommasinianus bulbs in the fall, about 2-3 inches deep and 2-3 inches apart from each other. The bulbs can be positioned in groups or scattered throughout the garden to create a naturalized effect.
Watering: Water the bulbs regularly, particularly during the first year after planting to help them establish. Once the plant is well-established, it will require less frequent watering. Ensure the soil is moist but not waterlogged.

Crocus tommasinianus is hardy in USDA zones 4-8. In colder climates, it is advisable to cover the bulbs with a layer of mulch or evergreen boughs during winter. This protective layer helps insulate the bulbs from extreme cold temperatures and provides additional protection.
