African Marigold Sierra Yellow

African Marigold Sierra Yellow — variety description

African Marigold Sierra Yellow (Tagetes erecta) is an annual flower of the Daisy family (Asteraceae). Grown from marigold seed, these annuals are tireless flowering plants with giant blooms that have a flat pompon shape.

The flowers have masses of small petals that are ruffled and frilled, creating a highly textured bloom.

The colour and texture make a dazzling display in the garden, border or in a container. These large yellow marigolds are good even for cutting and look good in bouquets too.

The African (tall) marigold produces large, dense pompons in yellow and orange from June until the frosts. Repels nematodes and pests — a good neighbour for vegetables.

When to sow African Marigold Sierra Yellow

African Marigold Sierra Yellow seeds are sown in April and May. The plants flower from June to October. The months are a guide for a temperate climate — in warmer areas sow 1–2 weeks earlier, in cooler or upland areas, later.

How to sow and grow African Marigold Sierra Yellow

• Sowing method: seedlings or direct
• Depth: 0.5–1 cm
• Spacing: 30–40 cm
• Germination: 5–8 days at 20–25 °C
• Position: sunny spot

Sow seeds on the surface of the compost and cover with a very fine layer of dry vermiculite or finely sieved compost. In a temperate climate, place the seeds in a propagator or seal in a polythene bag and keep at about 21-25°C until the seeds germinate. This will take about 7-21 days. Do not exclude the light, as it helps germination. When the seedlings are large enough to handle, transplant them individually into 7.5 cm pots or multi-cell trays. For temperate climates, before planting out, acclimatise the plants to cooler conditions by leaving them outside for a few hours a day for a few weeks. Plant out when all risk of frost has passed, about 30 cm apart.

Sow for seedlings in March–April, or directly after the last frosts. Plant in sun; remove spent flowers for abundant blooms.

Flowering and uses

Excellent for cutting, borders and for planting among tomatoes and cabbages.
