Crocus tommasinianus 'Ruby Giant'

Tommies

Crocus tommasinianus 'Ruby Giant' reaches 4 to 6 inches tall, featuring deep violet-purple, star-shaped blooms with bright orange anthers. This early-spring variety spreads vigorously, forming dense drifts that return reliably year after year. Its slender, grass-like foliage adds texture, complementing the rich floral display.

Ideal for naturalizing, rock gardens, borders, and lawns, it is deer-resistant and thrives in full sun to part shade with well-drained soil. Flowers open only in bright light, closing at night or on cloudy days.

Growing and Maintenance Tips for Crocus tommasinianus 'Ruby Giant'

Planting: Plant species crocus corms in fall, about 3 inches deep and 2 to 3 inches apart, with the pointed end facing up. They naturalize well, so choose a spot where they can spread over time.
Location: Full sun is ideal, especially in early spring before deciduous trees leaf out. They also perform well in light shade.
Soil: Well-drained, moderately fertile soil is best. Sandy or loamy soils are ideal; amend clay with compost or grit.
Watering: Water after planting and during active growth in late winter and early spring. Once dormant, they require little to no water.
Temperature: Hardy in USDA zones 3–8. No winter protection needed in most climates.
Fertilization: Apply compost or a low-nitrogen fertilizer in early spring as growth begins.
Pruning: Allow foliage to die back naturally after flowering to nourish the corms for next year.
Propagation: Naturalizes easily by offsets and seed. Divide clumps in summer when dormant if overcrowded.
Pest & Disease: Generally pest-free and deer-resistant. Rodents may dig up corms—planting with gravel or using deterrents can help.
