Aromatic perennial, rich in nectar, with violet spikes and a scent of liquorice and aniseed

The Korean mint seeds from the Association Kokopelli produce a very hardy perennial, Agastache rugosa, which reaches 1 m to 1.20 m. From June to September it bears edible purple flower spikes, which are visited by bees, and gives off a scent of liquorice and aniseed. The packet contains 200 organic seeds, to be sown on the surface from March to May.

Agastache rugosa, known as Korean mint, is a very hardy perennial with bright green leaves, forming a clump of many upright stems of 1 m to 1.20 m. Its scent combines liquorice and aniseed, so it is enough to crush a leaf to recognise it. Sown once, it regrows from its crown every spring for several years, which makes it a plant to settle in for the long term rather than to resow each season.

🐝 Purple spikes all summer

From June to September, each stem ends in a spike of purple, fragrant, edible flowers, which bees, bumblebees and butterflies visit continuously. This long flowering period matters if your vegetable garden or greenhouse depends on insects for fruit set: an agastache planted near your courgettes or cucumbers draws pollinators to them throughout their flowering period, while you harvest its leaves. The dried spikes stay decorative for a good part of the winter.

🌱 A surface-sown seedling

Agastache seed is sown on the surface, without being covered, in pots or trays placed in a bright, sheltered spot, from March to May. Press it down with a finger to ensure contact with the grow medium, then keep this damp without soaking it, at around 20 °C. Germination is slow and uneven, as it takes 1 to 3 weeks depending on the seeds. You then prick out each seedling into an individual pot at the 2 to 4 leaf stage, before planting it out after the last frosts, 30 cm apart in every direction. The 200 seeds in the packet easily cover a whole bed.

Set the agastache on a drained media bed

Agastache needs little water and prefers a light, well-drained soil, which sets it apart from a true mint. In your aquaponic system, it therefore belongs in a grow bed filled with clay pebbles, subject to flood and drain cycles, rather than on a deep water culture raft where the roots sit in water permanently. A bed of 45 to 80 litres gives the depth that a perennial clump fills year after year. The guide to grow media compares the air each medium leaves around the roots.

🍵 Leaves and flowers to harvest

Harvesting follows flowering, from June to September. Cut the young shoots just above a pair of leaves rather than stripping the stems: the plant branches from this point and produces new shoots, which are also the most fragrant. The flower spikes are picked in bloom, for the kitchen, or left standing if you want to feed pollinators until the end of summer. The leaves are used fresh or dried in the shade, and they then keep their fragrance for your winter infusions.

As an infusion

The leaves, fresh or dried, make an herbal tea with a note of liquorice and aniseed.

In the kitchen

Edible flowers can be scattered over a fruit salad or a dessert.

In the garden

Flower spikes left in place feed bees and bumblebees until September.

These seeds are open-pollinated heritage seeds that breed true: a spike left standing until it is ripe provides seeds that give the same plant again, and you can harvest them at the end of summer to enlarge your border. Since the clump regrows on its own from its rootstock after winter, without protection in most regions of France, you have nothing to resow to find your plants again the following spring. The practical aquaponics calendar helps you fit this spring sowing alongside your other crops.

    What you need to know

    • Do not cover the seed. Placed on the surface and pressed down with a finger, it stays in contact with the damp grow medium and receives the light it needs to germinate.
    • Germination is slow and uneven, taking 1 to 3 weeks. Do not empty the pot after 10 days thinking it has failed, as this is the normal pace for this plant.
    • Choose the position carefully from the start. This is a perennial that will stay in the same spot for several years.
    • In a water-based system, choose a media bed with flood-and-drain cycles rather than a raft. Agastache needs little water and grows less well with its roots permanently submerged.
    • Cut just above a pair of leaves rather than stripping the stems. The plant branches out with every cut and produces new shoots, which are the most fragrant.
    • Plant it close to your flowering crops. Its spikes attract bees and bumblebees from June to September, during the flowering of courgettes and cucumbers.
