Basil

Basil is a culinary herb in the mint family, grown for its aromatic leaves and widely used fresh or dried in cooking.

Updated July 30, 20261 min readCited sources

Basil is a warm-season herb commonly grown in Canadian gardens as an annual, since it cannot survive frost. It is prized for its aromatic leaves, especially sweet basil used in Mediterranean cooking.

What it is

Basil is an aromatic herb in the mint family (Lamiaceae), grown for its tender, fragrant leaves. Sweet basil (Ocimum basilicum) is the most common culinary type, though other cultivars vary in leaf size and flavour. In temperate climates like Canada, it is typically grown as a warm-season annual because frost kills the plant.

Why it matters

Basil is a staple in Italian and Mediterranean cooking, used fresh in pesto, sauces, salads, and as a garnish. Its strong aroma and flavour are most pronounced when fresh, making it a popular kitchen-garden herb. Regular harvesting encourages bushier growth and a longer harvest period.

Key details

Basil needs full sun, moist well-drained soil, and warm temperatures. Plant after frost danger passes. Harvest by cutting stems just above a leaf pair to promote branching. Pinch off flower buds to keep leaves coming. In Canada, basil is grown outdoors as an annual or indoors in containers.

In short

  • Basil is a warm-season annual in Canadian gardens.
  • Harvest by cutting above leaf pairs for bushier growth.
  • Sweet basil is the standard culinary type.
  • Pinch flower buds to extend leaf production.
Canadian angle

Basil is a common herb in Canadian home gardens and indoor containers, but it is usually grown as an annual outdoors because Canadian winters are too cold for frost-sensitive plants.

Quick questions

How do you grow basil?
Plant basil in full sun after frost danger has passed, in moist but well-drained soil. Water regularly, avoid waterlogging, and pinch the tips to encourage branching.
How do you harvest basil?
Harvest by snipping stems just above a lower pair of leaves or leaf nodes, rather than picking single leaves. This helps the plant regrow and become bushier.
Is basil a perennial?
Basil is usually grown as an annual in temperate climates, but it can be perennial in frost-free tropical or subtropical conditions.
