Perilla frutescens 'Britton' - SeedsKorean perilla, Beefsteak plant, Perilla mint

Grow this tender perennial as an annual. Sow seed on the surface of good free-draining, seed compost. Cover with a fine sprinkling of vermiculite. Place in a propagator or seal container inside a polythene bag and place at 20-25C (68-77F) until after germination which takes 14-21 days. Do not exclude light, as this helps germination.

Transplant seedlings when large enough to handle into 7.5cm (3in) pots and continue to grow on indoors in cooler conditions. Acclimatise to outside conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart.

Harvest leaves as required from May to October.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
