Perennial & Biennial Seeds


Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Nepeta cataria ssp. citrina

Nepeta cataria ssp. citrina

Lemon Catmint, Nepeta cataria 'Citriodora'

 Quite unlike ordinary catmint, handle or squeeze the leaves and they give off a rich lemony fragrancy which pervades the garden with rich flowery perfume on still, warm summer evenings. It's easy to grow and can be treated as either annual or perennial making a good border or summer hedge plant. Fashion conscious cats are taking it up in droves as the 'in' catmint to brush-up against. 'William' who's enthusiasm for catmint has not diminished since his last starring role amongst T&M's ordinary catmint 11 years ago, was persauded (on a full stomach) to pose against these lemons so that you would know about his new found catmint fragrance delight 'Lemon Scented Catmint'.
