Marigolds are easy-peasy to grow, add loads of colour to the garden/pots and bees love them. They're also great to use when making seed paper as they're long and fine/flat.
Seeds come in packs of 100 seeds.
Marigold seeds are a mixture of yellows, oranges and deep orange/red.
If you are wanting to make seed balls I would recommend using a different seed as these are quite long and don't work very well when used in ball form, calendula seed would be more suited.
