Growing Japanese

 OLYMPUS DIGITAL CAMERA

When Debbie and I were talking about what might make a good choice of guest post topic for her blog, she mentioned her current interest in Japanese cookery. It’s a part of the world I am interested in, too, although my understanding of Japanese cuisine is in its infancy. But a lot of the plants we grow in the UK originally came from the temperate regions of the Far East, and so I thought it might be fun to look at some of the plants we can grow that have ‘Japanese’ in their common names. It might not be that they all originate from Japan; the naming of plants (with their common names, at least) is a murky business full of intrigue and confusion. Welsh onions, for example, don’t come from Wales, although they will happily grow in gardens there.

In the early days of my garden I planted Japanese onions. Some of the varieties of Japanese onions have Japanese-style names; others don’t. The difference between Japanese onions and regular onions is the time at which they’re planted. I chose them because it was autumn and I wanted to plant something in my garden. Japanese onion sets are put in the ground in the autumn, overwinter and produce bulbs slightly earlier in the year than their spring-planted relatives. There’s some suggestions that they don’t store as well as maincrop onions, but I’ve never had a problem with that. It’s quite hard to grow as many onions as you need in a year, unless you have an allotment or a very large garden. Some gardeners grow Japanese onions for an early crop, but give the majority of their space over to maincrop onions. Both can be grown from seed, as well as sets, and are readily available from seed catalogues and garden centres.

A plant that isn’t as well-known as is should be is the Japanese wineberry. It grows like a raspberry, and its berries are very similar, but until they are fully ripe they are encased in a calyx (like a shell) that keeps the birds from pilfering your harvest. The plants are very pretty, with dark green leaves on their scrambling stems, white flowers and their bright red fruit. They are quite bristly though, so don’t plant them right next to the garden path. Assuming any of your harvest makes it back to the kitchen (and one day I will grow enough to make that happen!) then you can use them in the same ways as raspberries, but they have a delightful flavour all of their own.

When people talk about growing quinces, they’re normally talking about Cydonia oblonga, a small tree that grows large, yellow fruits that are as hard as rocks. They’re sought after by foodies for making quince jellies and jams, or including in pies. Most people who grow the Japanese quince (Chaenomelesspecies) grow them for their ornamental qualities – they produce stunning blossom in the spring time. They’re also smaller plants, suitable for smaller gardens. A lot of people don’t know that they also produce edible fruit. One of the tastiest is said to be the popular variety ‘Crimson and gold’, and you can probably guess what colour show it puts on for you!

You’ve probably heard of the dreaded Japanese knotweed, a plant that was introduced for its ornamental value but has rapidly become invasive in the UK. If you’ve got it in the garden you need to be careful how you remove it – improper disposal of Japanese knotweed is illegal, and one of the ways in which it is spreading to new territory. Enquire of your local council what facilities they have for safe disposal, but there are people who go foraging for it to eat like rhubarb, so you could always try eating it into submission.

One you may not be familiar with is the Japanese prickly ash, which is one of the Zanthoxylum species used to grow Szechuan pepper. It’s a small, fragrant tree – and yes, it is prickly. Just one would give you more Szechuan peppercorns than a family could use in a year, even if you’re very big fans of Chinese 5-spice (for which it is one of the main ingredients). Not only does it give you the opportunity to grow one of your own spices, you can use it to play tricks on unsuspecting guests. One quick nibble of a Szechuan peppercorn will set your mouth vibrating for quite some time. It’s not unpleasant, but it is unexpected!

Other less familiar plants include Japanese parsley, or mitsuba – an annual herb that’s easy to grow, and for which seeds are readily available. Japanese ginger, mioga, is a little harder to track down (try Poyntzfield Herbs) but is a hardy plant that grows outside in the UK. It’s the flower shoots that are used (rather than the roots of regular ginger), and you do have to be wary of slugs, who find it just as delicious as we do. Japanese horseradish is wasabi, and you can grow that here too, although most of the wasabi we buy in shops is (apparently) regular old horseradish with a bit of green food dye. And, of course, there’s Japanese burdock, or gobo, which is a plant with impossibly long, edible roots.

I’m sure there’s plenty more I’ve forgotten, so if you can think of one you can add it in the comments!

  1. Thanks Emma, for popping in on your virtual book tour.

    Growing this far north can be a challenge. Knotweed thrives in some places, alas, and competes with native species. I planted Japenese ginger in the Autumn, but so far there are no signs of it coming back up!
