Wasabi: discover its flavour and how to grow it

Why grow Wasabi?

In this Semailles offering, Wasabi is a named wild rocket selection of Diplotaxis tenuifolia, with finely cut leaves. It is not a true wasabi plant.

Choose this offering if you want peppery, finely cut leaves. The trade name Wasabi is also used elsewhere, so always check the botanical name with a new purchase.

How this choice tastes

The source describes a strong flavour reminiscent of wasabi. The comparison is culinary and says nothing about botanical relationship.

From harvest to kitchen

Use a little young leaf in sandwiches or salad. Controlled quantities let you match the sharp accent to the dish.

What needs attention when growing

Sow in free-draining soil or a container and preferably pick young. Keep moisture regular for continued leaf growth.

Harvest tender, young leaves in small portions. Taste a single leaf before using the same amount as you would of milder rocket.

Choose by flavour, shape and use

Geteeld: Cultivated rocket has relatively broad leaves and is offered as a quick leaf crop. General rocket products are grouped as the same practical type choice. Pick young leaves for salad or add at the end of cooking. A little can suffice.

The source describes cultivated rocket as milder and aromatic. Its usual pepperiness is not a fixed heat level.

Wasabi: In this Semailles offering, Wasabi is a named wild rocket selection of Diplotaxis tenuifolia, with finely cut leaves. It is not a true wasabi plant. Use little young leaf on bread or in salad, adjusting its sharp accent to the dish.

Choose the type to suit your harvest

Cultivated and wild rocket are different plants with different germination and lifespans. Check the species on the packet. For quick young leaves, a small sowing is practical; follow specific raising advice for wild rocket.

A small, sound start

Sow a short row in a fine, moist seedbed and keep seeds moist during germination. Choose depth and timing for your type. Another small sowing gives fresh leaves without a whole bed bolting at once.

Light and soil that can drain

Choose a bright spot and prepare a fine enough surface for the small seeds or young rootballs. Water must be able to drain away after rain. In a pot, check that the drainage holes are clear; a layer of wet soil does not help produce a healthy leaf harvest.

Care for the young leaves

Cut young leaves without repeatedly removing the whole growing point if you want further picking. Regrowth depends on type and condition. Do not keep an exhausted or flowering crop just because another harvest was planned.

Harvest for quality

Pick young leaves as needed and use soon after harvest. Older leaves or warm, dry conditions can strengthen flavour. Taste a leaf from a clearly identified edible plant before harvesting a whole platter.

Recognise what the leaves tell you

Flea beetles make small holes in young leaves. Fine mesh and even growth help protect young crops. Species, season and stress influence bolting. For a new sowing, compare position and growing time above all.

Fresh leaves start with a small picking

Harvest at a cool time and keep the leaves cool after picking. Wash them before use and remove damaged parts. A small fresh portion wastes less than harvesting a whole container when you only need a handful.

Make room for the next round

Record sowing and the first harvest so you can compare what works in your space next season. Do not leave an empty row unplanned for long. A new batch within a suitable window gives a better spread than hoping overmature leaves will become young again.
