Key benefits

  • Sweet anise flavour that holds up in the heat of a wok
  • For green curries, stir-fries and noodle soups
  • Glossy leaves on purple stems with purple flower bracts
  • About 40cm tall and ideal in pots
  • Packet of about 120 seeds with growing instructions

Thai basil brings the sweet anise and liquorice note that defines a good green curry, and it holds that flavour in the heat of a wok far better than Italian basil. Glossy, pointed leaves sit on purple stems under tight clusters of purple flower bracts. Ocimum basilicum var. thyrsiflora is the basil of Thai, Vietnamese and Lao cooking: tear it into stir-fries, curries and noodle soups, or pile it raw beside a bowl of pho.

Sowing and growing

  • Sow indoors March to June, 3mm deep, on a warm windowsill or in a propagator
  • Germination: 5 to 10 days at around 20°C
  • Move outside to a sunny, sheltered spot from June, once nights stay mild
  • Position: full sun in free-draining compost; ideal in pots
  • Height: about 40cm, with a spread of 20cm
  • Harvest: pick leaves from about 6 to 8 weeks after sowing, pinching out tips and flower spikes to keep plants bushy
  • Tender annual: it will not survive frost

What you receive: a packet of about 120 seeds from Piccolo Seeds, with growing instructions on the back.

Frequently Asked Questions

When should I sow Thai basil seeds?

Sow indoors from March to June. Basil stalls in cold compost, so a warm windowsill or propagator at around 20°C gives the quickest start. Sowing a small batch every few weeks keeps fresh leaves coming until autumn.

Can I grow Thai basil in a pot?

Yes, it is well suited to pots and grows to about 40cm. Use free-draining compost, keep it in a sunny, sheltered spot and water when the surface starts to dry. A kitchen windowsill works well all summer.

How is Thai basil different from sweet basil?

Thai basil has a stronger anise and liquorice flavour, purple stems and purple flower bracts. Its leaves are firmer and keep their flavour when cooked, which is why it is used in curries and stir-fries rather than added only at the end.
