Gardening book sparks new ideas

Here in New England winter is long, especially for gardeners. We want to be outside in the garden but most days we can’t really do much. I compensate by learning about gardening from books. I recently finished a good one, Hummelo: A Journey Through a Plantsman’s Life by Piet Oudolf and Noel Kingsbury.

At over 400 pages it might seem daunting, but I’d estimate that nearly half of those pages are color photos of the gardens Piet Oudlof designed, with plenty from his home in Hummelo, Holland. It is written by Noel Kingsbury, a well-known British garden writer, and by Oudlof himself.

Piet (which is pronounced Pete) Oudolf was the primary designer of the High Line Gardens in New York City, a garden planted on a section of an abandoned elevated railway line in midtown Manhattan. This 1.45-mile planting is consistently rated in the Top 10 most visited places in New York City.

The book follows Oudolf’s life as a garden designer and plantsman. In addition to the High Line, he designed gardens in Chicago, Detroit and many in Europe. The book follows his professional life and illustrates the changes nicely. Many plants in the photos are not labeled, but more advanced gardeners will recognize them, and many are mentioned in the text. And although some common names are used, most are identified by the scientific names with the genus, species and cultivar, which I find helpful when studying the plants and finding out if the plants are hardy in my zone.

So what makes Piet Oudolf one of the most famous garden designers ever? First, he is a highly accomplished plantsman. When he specifies plants for a garden, he knows what they need to do well. He started out with his wife, Anja, growing most of the plants he used in his designs, often growing and selecting plants for years before using them.

He knows each plant including its root system and its capability to fill in spaces by seeding in or spreading by rhizomes. He grew and used plants that were largely disease-resistant. His gardens rarely need to be re-planted because the plants seldom fail. I should note that now he does not grow his own plants, he just specifies them and has others grow them for him, often from stock he perfected.

Piet Oudolf uses many tall grasses in his designs. He loves the way they provide structure and form to a design, and that they last well into winter. He is less interested in color than many designers. He loves the look of seed heads and stems after the (relatively short) bloom period is over. He is quoted in the book as saying, “A plant is only worth growing if it also looks good when it is dead.” Since he bred plants for toughness, I assume he means dormant, not dead.

Oudolf is a rule-breaker. He tried things that others had not. He is quoted as saying in the book, “I discover beauty in things that on first sight are not beautiful. It is a journey in life to find out what real beauty is — and to notice that it is everywhere.”

Early on in his career, Piet Oudolf used large blocks of a single species of a plant. But as he refined his designs, he started intermingling a few large, tall plants inside a block. He planted them repeatedly, as repetition adds a sense of unity and coherence to a garden. Unlike many designers, he actually lays out his gardens himself instead of drawing a plan and handing it off to gardeners. Oudolf is first and foremost a gardener. He loves plants, and knows them like his ever-present dogs.

What did I learn from this book? Given a large space to design, like Oudolf, I would use largely native plants. They are tough and if properly sited will last well. I like his philosophy that plant diversity is good but that too much diversity can overwhelm our ability to appreciate the whole.

I am, by temperament, a plant collector — I want to try lots of plants. But seeing the photos of Oudolf gardens, I recognize that buying — or growing — several plants instead of just three (my usual purchase), I can create a more powerful display.

Reading this book I made notes of plants I want to try. Among these is Eryngium giganteum, a sea holly that gets to be 3 to 4 feet tall with spiny egg-shaped blossoms and white bracts. Miss Willmott’s Ghost is readily available online, though I have never seen it for sale in a nursery.

Another plant that looks great is Agastache nepetoides, yellow giant hyssop. It is deer-resistant and big: It grows to 6 feet tall with flower spikes up to 16 inches long. In fall and winter the dry seed heads are fabulous, particularly in counterpoint to dry grasses.

I feel blessed that I was able to meet Piet Oudolf and interview him at his home in Hummelo, Holland, in 2007. He was very generous with his time and his knowledge.

This wonderful book was produced by Monacelli Press and is available in paperback for $40. To me, or any serious gardener or designer, it is a treasure. You might like to thumb through it before you decide if it is for you, especially if you are a beginning gardener. If you have big spaces to fill, you will get many ideas.

Plan what you’ll plant

I am probably not the only person who is determined to lose a little weight after all those delicious but fattening meals and desserts served up over the holidays. One way to feel satisfied and lose weight is to eat more salads and enjoy more vegetables. That’s my plan, anyway, and I recently took stock of what is lingering on in my storage fridge. I still have some nice veggies from summer that still taste good and are satisfying my hunger.

Digging around the vegetable drawer I noticed several kohlrabi I grew last summer, but that had not been touched in months. I was prepared not to like them because they had been stored so long. I peeled one, chopped it into half-inch cubes, and added to my nightly salad. It was delicious! It’s even tasty as low-calorie snack food just by itself.

Kohlrabi is in the cabbage family, but not well-known or much grown. It looks like a space alien in the garden: It is an above-ground root vegetable of sorts. Round or oblong, it can be green or purple, with leaves poking out of the beet-like “tuber” on bare stems. It is crunchy, and tastes a bit like broccoli, which is in the same family. It can be used to make coleslaw when grated with carrots.

Buy a packet of kohlrabi seeds and plant them in early June or late May. They are fast-growing plants and only need a bit of space to grow well. If you want kohlrabi all winter for adding to stir-fries, plant a green one called ‘Kossak,’ which gets large — up to 8 or 10 inches in diameter — and stores for up to four months in a cool, high-humidity place like the vegetable drawer of your fridge. I get seeds from Johnny’s Selected Seeds in Maine, but it is also available from High Mowing, Gurney’s and Park Seeds, among others.

I also found half a purple cabbage that had been lurking in my vegetable drawer since September. I expected it to be stale, but it was fine. Cabbage is easy enough to grow, but I often don’t bother because I don’t use it much — it is cheap and readily available. I grated some and added it to a green salad, adding color and bulk.

I had a great onion crop last summer. I buy onion plants from Johnny’s Seeds most years instead of babying seed-started plants indoors. When I start from seed, I start them under lights around March 1. When I start my own, even with intense light close to the seedlings, they are always a bit flimsy. Some of the plants I get from Johnny’s are nearly as thick around as a pencil, and take off and start growing immediately. The kind I grow are yellow onions, one called Patterson. They keep for months in a cool location, but will sprout and soften if left in the warm kitchen in a bowl.

The plants come in bundles of 50 to 60, according to their catalog, but last year I got closer to 100 plants per bundle. Onions don’t like competition, so weed early and often. Space your onions about 3 inches apart in the row, with rows at least 8 inches apart. They like fluffy, rich soil so be sure to add lots of compost and stir it in well. You can also start onions from “sets,” which are like little bulbs but less vigorous than plants.

What else am I eating from the garden now? Garlic. It is easy to grow, but if you didn’t plant any last October, you’re probably out of luck. It sets its roots in the fall, goes dormant, and pops up early in the spring. It is rarely available to purchase in the spring. I was out in California one spring and bought some soft-necked garlic in the spring, and it did fairly well here. You could try planting some of last year’s garlic, come spring, if you have any left over but it’s not recommended.

Potatoes are also a mainstay of my winter menu. I know, they are not usually recommended for dieters. But that is partly because of how they are served. They are a healthy starch, but many of us tend to load up potatoes with sour cream or butter. Add them to a stew or stir-fry, and they are still tasty but much less calorific.

I went 20 years once without buying a potato. I grew plenty, and saved out some for planting each spring. By only eating my own, I went a few months without any while waiting for my new crop to be ready. But it was a matter of principle to only eat my own. Commercial potatoes, if not raised organically or following IPM guidelines, can carry heavy pesticide loads.

The trick to getting lots of potatoes is to grow them in full sun. You can get potatoes where there is only six hours of sun per day, but the more sun, the more potatoes. And don’t let the potato beetles defoliate your plants. Check leaves, including the underneath side, for orange egg masses or larvae often when they are starting to grow. They can multiply exponentially if you let early beetles multiply.

Having a vegetable garden is, of course, a certain amount of work. But not only does it provide me with good, healthy, organic veggies; it also saves me lots of money and keeps me active in the garden. As we get older, the more exercise we get, the better. So start reading the catalogs or websites of seed companies, and plan what you will plant, come spring. Me? I can’t wait!
