Why Grow Marigold Flower Seed?

Another non-stop flowering plant for the summer season. Once planted in their final position, multiple flowers will cover Marigold’s crown all the way until the turn of the season. Suttons have lots of exciting marigold varieties and the choice of this genus is fantastic.

Marigold seeds come in two main varieties; French and African marigolds. Both produce bright, vibrant and eye-catching flowers consisting of yellows oranges and reds.

The French marigold seeds are easy to grow and weather tolerant. They need to be sown during February and March under glass in gentle heat. Alternatively, the seeds can be sown directly outdoors during April and May to flower between June and September. 

The African marigold seeds need to be sown between February and April, again under glass in gentle heat. They will flower from June to September.

The Marigold is termed a half-hardy annual, expressed by HHA written on the corner of the packet. It means it is a tender plant that needs to be protected from the cold.
