Allium Tall 'Silver Spring'

Ornamental Onion

Allium ‘Silver Spring’ reaches 24 to 30 inches tall, producing elegant, rounded umbels of creamy‑white florets each marked with a deep rose‑purple eye that intensifies as the bloom matures. The flowers open in late spring to early summer, drawing bees and other pollinators while maintaining strong deer resistance and excellent drought tolerance once established. Thriving in full sun and well‑drained soil, this variety brings a refined, bicolor accent to mixed borders, gravel gardens, and late‑spring perennial plantings, where its airy structure adds both movement and contrast. Product of Israel.

Growing and Maintenance Tips for Allium Tall 'Silver Spring'

Timing: Plant in fall before the ground freezes to ensure proper root development. Ideal soil temperature for planting is 60°F or colder.
Location: Choose a sunny, well-drained spot—poor drainage can cause bulb rot.
Depth & Spacing: Bury bulbs two to three times their height and space them six to twelve inches apart for optimal growth.
Soil: Maintain a pH of 6 to 7 and enrich with organic matter for better drainage.
Watering: Keep soil moist but not soggy during initial growth; once established, alliums are drought-tolerant.
Foliage Management: Leaves yellow after blooming—plant among perennials to disguise fading foliage.
Deadheading: Remove spent flowers to prevent self-seeding unless you want naturalized clusters.
Fertilization: Apply a balanced fertilizer in early spring to support strong blooms.
Pest & Disease Resistance: Alliums are deer and rabbit resistant but avoid planting in areas with excessive moisture to prevent fungal issues.
Crop Rotation: Change planting locations yearly to prevent soil-borne diseases.
