It Helps to Know Your Vegetables’ Family Trees

A few carrots that didn’t get pulled one summer made their beautiful lacy flowers the next year, and it was easy to see that those blooms looked a lot like Queen Anne’s lace, cilantro blossoms and the diminutive chervil flower. Were they somehow related? More than just a pretty face, I knew there was something behind these flowers and the gorgeous vegetables I loved, something that united them and their forms, flavors and behaviors. But what?

I took those unread botany books off the shelves and found out that yes, these were all members of the umbellifer family and they all make umbel-like flowers, though varying enormously in size. This family includes a lot of  wild but familiar plants, including the deadly hemlock, and it turns out that  — minus the hemlock — they all happen to be harmonious in our mouths, both the vegetables and the many herbs in that family.

It’s all relative when it comes to vegetables

I started looking more into plant families, who is in them, their stories, their shared characteristics and the way they play in our kitchens. Like people, plant family members are indeed relatives.

The daisy (composite) family, a group of ruffians, includes the prickly artichokes and cardoons; salsify and scorzanera all with their habit of oxidizing; the bitter chicories; plus milk thistle, dandelion and burdock — a feisty bunch of plants. Break any of the roots and a thick white sap appears. Taste it and you will recoil from its bitterness. But a lot of these bitter plants are good for the liver, it turns out. Interesting.

Members of the nightshade family have been universally resisted wherever they’ve been introduced. Tomatoes were thought to cause stomach cancer. The Russian Orthodox Church believed potatoes were not food because they weren’t mentioned in the Bible, and besides, why eat what a dog didn’t even find interesting? Eggplant was thought to cause leprosy, and the consumption of eggplant (and nightshades in general) stimulates the pain of arthritis, which is why some people avoid it, even today. Belladonna got its name because when ingested, the pupils of the eyes grew large and dark, which was considered a form of beauty in women. The difficulties in this family, presumed or real, are due to alkaloids that can be deadly in large quantities but helpful in smaller ones; we all get our eyes dilated by the optometrist so the doctor can look deeply into our eyes, though not because of their lustrous beauty.

The chenopods, or goosefoots (yes, I looked at a goose’s gnarly foot to confirm the association), include spinach, chard, beets, wild spinach or lamb’s-quarters, and all are related to quinoa and amaranth, whose leaves can be and are eaten as well as the seeds. Speaking broadly, they are interchangeable in the kitchen with respect to flavor. And if you have chard bolting in your garden, might you still be able to eat the leaves as they becomes smaller and further apart on their ever-lengthening stems? Indeed you can. And at this stage they taste more like some of the wild greens they’re related to. This is the kind of stuff that I find fascinating!

Anyone who gardens has opportunities that deepen one’s vegetable literacy and excitement. You’ll find treasures that won’t appear in your supermarket, such as coriander buds that are still green and moist, so surprising in the mouth and so well-paired with lentils. You get to see — and eat — the whole plant, not just the parts and pieces that show up in the store. Broccoli leaves, as well as the crowns and stems, are quite tasty, and the same is true of radish and kohlrabi leaves.

Leeks produce enormous ribbons of leaves, sometimes referred to as flags, and indeed you can wave them back and forth to signal someone, if need be. When left in the garden over winter, the shanks can grow to a few feet in length(!), by which time a firm core has formed, too dense to eat, but a great ingredient for soup stock. When a leek is left in the garden long enough to bloom, its enormous spherical flower mimics that of the pretty chive blossom. And when you finally encounter a mature leek in the garden you can see that it is a mighty and noble vegetable (one variety is named King Richard). Is it surprising that the leek is the national symbol of Wales?

The name knotweed (the family that includes rhubarb, sorrel and buckwheat) refers to jointed stems, but you might see that the blossoms of these plants resemble the kind of embroidery that consists of little knots. Not the botanical definition, but my own, and you may have your own interpretation of names, too. I might add it doesn’t take much imagination to bring these three challenging plants together in a recipe.

Does any of this matter?  Yes and no. We can still buy vegetables and cook them without knowing a bit of botany or history. But it is enormously fun to bring the familial nature of vegetables into view, to know that what relates in the garden often does so in the kitchen, which encourages both confidence and daring. And if you garden at all, your eyes will be open to possibilities that just don’t exist elsewhere.

To me, vegetable literacy enriches our world — and our culinary possibilities — by regarding the whole, wonderful plant and its relatives, not just the pieces and parts of a few cultivars.

    I am excited to read this book. The more I know about the food I eat the better the food tastes, I think. And the cover of this book is enticing, and your writing is always engaging. So, again, can’t wait!!! Stories to tell my grand daughter over dinner! thanks Deborah.

    I like that- “the more you know about the food I eat, the better it tastes.” I feel the same way.
    Somehow knowing about it brings it into focus, taste too!
