Delphinium is an incredibly impressive perennial that thrives in cooler climates, full sun, and well-drained soil, making it ideal for cutting gardens in northern and coastal regions. Known for its uniform bloom time and closely spaced florets that create a full appearance, Guardian is both strong and vigorous, suitable for home gardeners and professional growers. Plant in the fall for hot climates or in the spring for moderate and cool regions to achieve first-year flowering. With excellent vase life and bold presence, this PanAmerican Seed variety delivers timeless appeal to any garden.
Delphinium Guardian is generally suitable for fall planting in USDA zones 5 and higher (unprotected), and zone 4 and lower with additional protection from a greenhouse, hoop house or frost cloth. This is strictly a guideline and we cannot guarantee winter survivability.
