Mint 'Peppermint' Seeds

Mentha x piperita is a vigorous Hardy Perennial (H5). It is well-suited to the UK climate, dying back to its roots in winter and bursting forth with fresh, aromatic foliage as soon as the spring temperatures rise.

The Container Rule: Mint is famous for its invasive "runners"—underground stems that spread rapidly and can quickly smother other plants. In a UK garden, it is almost always best grown in a pot or a dedicated trough to keep it from taking over your flower beds.

Pollinator Haven: While mostly harvested for its leaves, if allowed to flower in late summer, Peppermint provides a valuable nectar source for hoverflies and small solitary bees, helping to support your garden's natural balance.

Mint seeds are tiny and require light to germinate, so they should be sown with care on the soil surface.

How to Sow:
Sow indoors from February to May. Scatter the dust-like seeds onto the surface of moist, high-quality seed compost. Do not cover the seeds with soil—at most, use a very light dusting of vermiculite. Keep at 18-20°C; germination usually takes 14-21 days.

Where to Plant:
They are remarkably adaptable, thriving in full sun or partial shade. Peppermint prefers rich, moisture-retentive soil and dislikes drying out completely. A large pot situated near the kitchen door or on a semi-shady patio is an ideal home for this useful herb.

Ongoing Care:
To keep the plant producing tender, flavourful leaves, shear it back hard after the first flush of growth in mid-summer. Regular watering is essential, especially for container-grown plants during a dry UK summer. Divide the root ball every two years to prevent the plant from becoming pot-bound and losing its vigour.

Because Peppermint is best grown in containers, pair it with these pot-loving stars from our range to create a functional and beautiful display:

• 🍋 Lemon Balm: The Tea Garden Duo. Both Peppermint and Lemon Balm love similar conditions (moisture and light shade). Grow them in separate pots side-by-side to create the ultimate garden station for fresh herbal infusions.
• 🌼 Calendula 'Art Shades': The Colour Contrast. The vibrant orange and apricot tones of Calendula provide a spectacular visual pop against the dark green, purple-tinged foliage of Peppermint. Both are edible and brilliant for a productive patio display.

Sow indoors in spring for a summer-long supply of head-clearing peppermint leaves.
