Overview

Outsidepride Silver Blue Sea Holly seeds offer a bold, sculptural element for sunny borders. With up to 5000 seeds per order, you can establish a perennial display that returns season after season. The Silver Blue Eryngium features silvery-blue foliage and signature blue blooms that bring a cool, coastal vibe to any garden. The sturdy stems and distinctive texture create a long-lasting focal point in mixed borders and cutting gardens.

Grown in full sun and well-drained soil, this variety can reach up to 48 inches in height, delivering vertical interest for back borders or entryway accents. Space plants about 18 inches apart to support air circulation and robust growth. It suits USDA zones 4–8 and demonstrates resilience in drought once established, helping gardeners manage water more efficiently in dry seasons.

Long bloom season and cut-flower versatility

Expect blue blooms from early summer through late summer. The color remains vibrant and can be dried for lasting texture, making it a versatile option for fresh bouquets or dried arrangements. When dried, the blooms maintain their shape, adding structural interest to indoor displays.

Winter interest and garden resilience

Beyond the growing season, spiny foliage and preserved flower heads provide visual appeal in winter, adding form and texture to the landscape even as other plants fade. This enduring silhouette helps define beds and borders during colder months.

Low maintenance and wildlife considerations

Deer often avoid this plant, which can be advantageous for browsed landscapes. Once established, it generally requires minimal attention, thanks to tough leaves and self-supporting stems that resist common garden issues.

How to grow from seed

Seed handling is straightforward: surface-sow outdoors after the last frost, press the seeds into soil, and keep it consistently moist until germination. Expect germination in about 21–28 days. For best results, plant in well-drained soil with full sun exposure.
