The most OUTRAGEOUS Delphinium you can grow! No mildew-prone wimp that disappears after one season, but a reliably perennial, multi-spiking, extra-large-flowered jumbo delph to 6’ tall and 4’ across! Royal-blue spikes make sumptuous cut flowers! Grow in loamy soil with compost in Spring and Summer for huge spikes; cut back to 6” when spent for repeat bloom. Butterflies! Deer resistant.
