Adding a little spice to life

RHS Garden Rosemoor, in an out-of-the-way corner of Devon, is the most modest of the four RHS gardens, rarely shouting about its look-at-me attractions, preferring just to let people come and find out for themselves.

But oh, do make the effort: it’s a little gem. Winter gardens with forests of brilliant scarlet cornus and dazzling Betula utilis var jacquemontii, trunks scrubbed to a whiteness that glows; sheets of purple crocuses; craggy oaks and the intoxicating scent of Christmas box and witch hazels floating on the early spring air.

I was entirely distracted, though, by their exceptionally fine fruit and vegetable garden. One day I too will train my redcurrants in double cordons and grow sprouts as big as golfballs. And in particular, my eye was caught by one little glasshouse, packed with quite the finest selection of oriental greens I’ve ever seen in one place.

Mustard ‘Golden Streaks’

This was a revelation. We’re used to oriental mizuna, mibuna and mustard spicing up our salads in winter. But they’re also excellent as mature leafy greens, a vegetable in their own right, cooked lightly – a little like spinach – or stir-fried, or used in soups. The flavour takes a little getting used to, as it’s spicier than our tastebuds usually allow (with a few exceptions).

They’re strikingly good-looking – I hadn’t appreciated quite how handsome until I saw them en masse at Rosemoor. And being cool-weather plants, you can grow them through winter, releasing you from endless cabbages with a fresh, crisp flavour that sings on your tongue.

With some, you just eat the leaves; others yield crisp, water-filled stems or flowerbuds. Some, all three, so you can pick them at three different stages of growth. The varieties I spotted at Rosemoor were:

Red Komatsuna (Mustard Spinach): big, beefy red-tinged leaves. They had the green version too. Sue Stickland says this has a mild taste, ‘like a slightly peppery cabbage’.

Mustard ‘Golden Streaks’: like curly endive with deeply-cut, almost frizzy leaves. Often described as having a ‘sweet mustard flavour’ – whatever that means. A testing panel from the RHS found it had a ‘powerful peppery flavour’ but also said it was piquant, earthy and sweet.

Shungiku

Shungiku: leaves like chrysanthemums: not surprising, really, as that’s what they are. Its other name is chrysanthemum greens (chop suey greens is another alter ego). Sarah Raven describes the flavour as ‘strange, fragrant, slightly sweet and slightly peppery, with a good crunch’. You can eat leaves, the tight yellow flowerbuds and flowers – though petals only, not the bitter centres.

Mustard ‘Green-in-Snow’: brilliant green, serrated-edged leaves; and Mustard ‘Red Giant’: the only one I’ve grown, a familiar ingredient in salads with its reddish bronze tinted leaves. Both are getting towards the hotter end of the scale. According to Sue Stickland, ‘if you like watercress, you’ll love this’.

Mustard ‘Osaka Purple’: leaves so big they look like a loose cabbage: the purple is in the veining. The leaves are very hot and spicy in the raw – but once cooked they lose much of their bite and become richly-flavoured but mild.

Tatsoi ‘Yukina Savoy’

Tatsoi ‘Yukina Savoy’: big, puckered leaves of a deep, rumpled, velvety grey-green held up on strong, creamy stems. ‘Savoy’ describes the texture well: the leaves are thick, firm and meaty. Tatsoi and pak choi are often confused, and tatsoi is also known, just to be more confusing, as rosette pak choi: it has a similar combination of thick stem and leaves but grows in a rosette rather than that very distinctive pak choi fluted vase shape. The flavour is described as ‘strong’, but I think not peppery.

Cooking: recipes are – cautiously – finding their way into cookbooks. Pick the growth tips and dip in batter before deep-frying for tempura, or wilt large leaves in a tiny bit of water like spinach. Stir-fry in oil with spring onions, ginger and garlic; and cut thick stems into 10cm pieces, blanch in fast-boiling water for a minute or two, then stir-fry with a little sugar, ginger, rice wine vinegar and oyster sauce.

Joy Larkcom brought Asian greens to the UK and has written an excellent book on the subject (recently updated). But we all seem to have stopped at the baby-leaf stage. Oriental greens have so much more to offer: this year, I’m going to let them grow up.
