Spring/summer bloomFrost tolerant
Sweet peas must have well drained soil, so dig deeply and enrich with aged manure or compost before sowing seeds. Erect a well-anchored trellis, vertical netting or other support for vines before planting. Sow seeds in full sun in cool early spring weather as early as the ground can be worked. In mild winter areas, where the ground does not freeze, plant in fall; seeds will germinate and form strong root systems, then overwinter to bloom strongly in spring. Plant sweet pea seeds 1 inch deep and 2 to 3 inches apart. When seedlings are 2 inches tall, thin them 4 to 5 inches apart, to allow plants room to mature.
