Signet marigold seeds produce warm-season annual plants with a compact, finely textured, bushy growth habit and delicate, feathery foliage. These plants develop numerous small blooms over an extended period and are well suited to warm climates with a frost-free growing season. Signet marigolds perform best in full sunlight with well-drained soil and moderate, consistent moisture. Ideal for garden beds, borders, edging, and containers, they establish quickly and provide continuous seasonal color.
