Perennial Cornflower 'Gold Bullion' is a clump-forming perennial that brings late-spring color to gardens from zones 3 to 8. This variety produces solitary, fringed flowers with rich blue petals, reddish-blue centers, and distinctive black-edged bracts, each bloom reaching about 2 inches across. Growing 12 to 24 inches tall with a 9 to 12-inch spread, it thrives in full sun and poor to average soils, making it especially valuable for gardeners seeking low-maintenance perennials that handle drought and neglect with ease.

These blue cornflowers bloom from May through June in a season when many perennials are just getting started, offering early color on unbranched stems. The flowers are showy and fringed with unusual reddish-blue centers rimmed in black, a detail that catches the eye at close range. Perennial Cornflower spreads steadily by underground stolons to form naturalized colonies over time, particularly in cooler northern gardens, and it asks for almost nothing in return: poor soil, dry conditions, and minimal fussing are all it needs.
Perennial Cornflower is grown to naturalize meadows and informal garden spaces, where its spreading habit creates drifts of blue over time. The flowers attract butterflies throughout the bloom season, making it a choice for pollinator gardens and wildflower borders where color and wildlife support go hand in hand.

Remove spent flower stalks after the May-to-June bloom period to encourage tidiness and potential sparse rebloom in late summer or early fall. Divide plants every two to three years to manage their stoloniferous spreading habit and maintain vigor.
