Dittander

    Gardeners love testing new kinds of plants. Never mind if we lack money to buy them or space to plant them. Every year some new experiments must be tried. To not expand our collection is to stand still. Some of us go so far as to pine for a regulation that all new landscape plantings contain at least a percentage of untested plants. For the only way to learn about a plant's merits is to grow it. In 1997, so far, my own list of garden acquisitions new to me numbers 18 plants.
    This includes only species, not mere garden varieties. To include the latter, such as one kind or another of tomato or pepper, boosts the total higher, but is less significant: the flavor and performance vary much, but the general appearance and cultural needs are the same.
    The only thing in common of my 18 new plants is they're all edible, even ginseng, though it would be dumb of me to eat my only specimen of that famous herb. All my new plants but 4 were bought at local nurseries or plant sales; three were gifts from other gardeners; one I plucked from the wild.
    I was in Georgetown, at Gateway Park on the Duwamish River (the end of 8th Avenue S), and was poking around looking at the plants by an abandoned concrete structure --the Georgetown steam plant intake building. One plant stumped me. It was a strong perennial, partly evergreen, of the mustard family. Many were there, in big clumps. I took a piece home and planted it, curiosity eating me up. By and by I visited the library and sleuthed out the mysterious plant's identity: Dittander (Lepidium latifolium), a European native which was cultivated as a salad plant by the ancient Greeks. Its roots are a horseradish substitute.
    Dittander favors salt marshes, whether in Europe or in the New World. It has been found wild near Portland, also, and from Long Island to Massachusetts. Overall it is rare, found on beaches, tidal shores and waste ground.
    My goal in growing it in ordinary garden conditions is to discover whether it is a worthwhile salad plant to cultivate in Seattle. Someone has to find out. Apparently no North American nurseries sell it. Its previous role as an edible is lost in antiquity. Here's to resurrection of lost lore. Be assured, if Dittander succeeds in my garden, I'll share starts with friends, and no doubt some nurseries will begin selling it. This could be the beginning of something special. It could prove a dud. Only one way to find out.
    Dittander's flavor is hot and peppery, recalling mustard, cress and nasturtium. Regarding looks, it won't win any beauty contests, nor is it singularly ill favored. It certainly is tough, persistent and vigorous. Its Latin name fails to pique my curiosity, but I wonder is Dittander related to Dittany? The latter name, in use for various plants, originally was applied to one abundant on Mount Dicte in Crete.
