About Tagetes erecta 'Inca Gold'

Tagetes erecta 'Inca Gold' · also called Inca Gold Marigold, African Marigold Gold · flowering

'Inca Gold' is an F1 African (American) marigold from the popular 'Inca' series, producing large, fully double golden pompon blooms on sturdy, weather-resistant dwarf plants. Earlier and more compact than older African types, it suits bedding, large containers and cut flowers. It performs strongly in full sun and free-draining soil, flowering reliably through summer with deadheading.

Mature size: Roughly 25-35 cm tall and 25-30 cm wide.

Indoor size vs how big it gets in the wild

Tagetes erecta 'Inca Gold' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect roughly 25-35 cm tall and 25-30 cm wide.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Tagetes erecta 'Inca Gold' is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: feed at planting with a balanced fertiliser and apply a high-potash liquid feed every 2-3 weeks during flowering to support the large blooms; avoid excess nitrogen, which softens stems.
