Peppermint Seeds Mentha piperita by Franchi Seeds

Peppermint is a vigorous perennial herb with dark green leaves, high menthol content and an intense cooling flavour. It spreads quickly by underground runners, so grow it in a pot unless you want it taking over the garden.

Fresh peppermint leaves in hot water make a tea that is genuinely better than anything from a teabag. Also excellent in summer drinks, salads, lamb dishes and chocolate desserts. Once established, you will have more mint than you can use, which is not a bad problem to have.
