Swedish Flag Allium Mix Bulbs – Vibrant Yellow & Blue Ornamental Onion Duo, Deer Resistant, Fall Planting

Swedish Flag Allium Mix is a striking two-color combination that pairs vibrant golden-yellow and charming true-blue ornamental alliums in a dynamic duet that dances in borders, rock gardens, and bouquets before most other perennials come out to play. Inspired by the bold colors of the Swedish flag, this mix brings graphic color contrast and playful energy to late spring gardens, with the two varieties' colors complementing each other perfectly as they bloom in early summer — just after spring bulbs fade and right before the full bloom of summer perennials. Deer resistant, pollinator-friendly, and excellent for naturalizing in sun.

Planting & Care

Plant bulbs in fall in a sunny, well-drained spot. Place roots pointing down and the spike pointing up, 3–4 inches deep. Plant yellow and blue varieties together in clusters for the best color contrast effect. Water well after planting. Allow foliage to die back naturally after blooming. No heavy watering needed during summer rest. Naturalizes freely and returns reliably year after year.
