Giant Crackerjack Mix African marigold (Tagetes erecta) This vigorous mix produces large, full double flowers up to 15 cm across in shades ranging from primrose yellow to bright orange. The packet contains approximately 90 bare seeds. Plants reach about 90 cm tall and spread 30–45 cm. Their neat, bushy habit suits garden beds, large containers, and cut-flower bouquets. Flowering is early for this type of African marigold. The tall stems add structure to the garden, while the colour range creates a warm transition from pale yellow to intense orange. It is a useful choice when both height and substantial flower size are desired in an annual display.

For best results, sow indoors 4–5 weeks before the last frost and keep the growing medium near 22 °C. Germination generally takes 5–8 days. Cover the seeds lightly with coarse vermiculite and keep the mix moist until emergence, then reduce moisture without allowing seedlings to wilt. Use a porous, well-drained seed-starting mix and harden plants gradually before transplanting after frost danger has passed. After emergence, bright light and measured moisture help seedlings develop sturdy growth. You can rotate containers as needed to encourage balanced development before transplanting. Space seedlings so air can move between them as the foliage expands.

Plant in sun or partial shade in well-drained soil, spacing plants 30–45 cm apart. This African marigold tolerates a range of conditions and brief dry periods, but flowering is more generous with regular watering that does not leave the soil waterlogged. Removing faded flowers helps maintain a tidy appearance and prolonged bloom, generally from June through September. Position plants behind shorter annuals to enjoy their height without hiding the border. For bouquets, cut stems when the flowers are well formed. In containers, provide enough growing-medium volume to support the 90 cm plants, check moisture during hot weather, and avoid leaving the pot in standing water.
