Crocus 'Vanguard' Bulbs – Soft Gray-Blue & Purple, RHS Award Winner, Heirloom, Fall Planting

Crocus vernus 'Vanguard' is one of the most visually unusual and distinguished Dutch Crocus available — an RHS Award of Garden Merit winner (1983) and a heirloom variety dating back to 1934. The coloring is genuinely striking: soft gray-blue outer petals contrasting with light purple inner petals that, when the flowers open wide on warm days, create the illusion of bold, painterly stripes. Growing to 4–6 inches tall on 9+ cm corms, Vanguard blooms in April as a companion to very early daffodils — equally beautiful in sweeping border drifts, foundation plantings, containers, or naturalized beneath shrubs. Deer-resistant and fully hardy across a wide range of zones.

Planting & Care

Plant in sweeps beneath and between shrubs, in border fronts, or naturalized in lawn. Choose a well-drained, sunny to partially shaded location. Plant corms with pointed tip up, covered with soil to at least twice the corm height. Allow foliage to die back naturally after blooming to feed the corm for the following year. Deer-resistant and low-maintenance once established.
