An artichoke plant, which can spread into a silvery green fountain up to 6 feet across, makes a bold, handsome addition to any garden. Best of all, perhaps, this gem of a vegetable can be grown much more easily and in a wider range of climates than you might expect.

I remember having dinner at a friend’s home and seeing an artichoke on my plate for the first time. I wondered how I was going to eat this intriguing vegetable. My friend’s mom showed me how to approach the task. I plucked the leaves, dipped them in melted butter, and tugged the stem end through my teeth to draw off the tender meat. It was child’s play.

That was a long time ago, but I remember being completely satisfied when all the leaves were gone. Then she told me about the hidden treasure, the tender artichoke heart. The artichoke is a gold mine of rich, earthy, hearty flavor, a vegetable with a taste and texture like no other.

The artichoke, Cynara scolymus, can be grown almost everywhere in the United States, except possibly Florida, where the summer is too hot. The ideal growing conditions are cool and moist summers and mild winters.

If you live in a climate colder than Zone 8, your best bet is to start new plants each year. If you have a mild winter and mulch well, the artichokes may survive as perennials. Remember, it’s the artichoke’s roots that need protection.

Using transplants, you can grow artichokes as annuals in cold-winter climates with 90 to 100 frost-free days. I know people who have grown delicious artichokes in Connecticut, Maine, and Massa­chusetts. Artichokes you start indoors in late winter or early spring will be ready to harvest from late summer through early fall.

Gardeners who are lucky enough to have the best growing conditions may be able to harvest artichokes throughout the year. For these people, it would not be unusual to harvest 30 artichokes per year per plant.

Artichoke starting options

There are three ways to begin your artichoke garden: with seed, with shoots taken from existing plants, or with dormant roots. Artichokes are easily started from seed in a greenhouse or under fluorescent lights. Starting in February, I seed directly into 4-inch containers. Getting a head start is a vital step in producing artichokes the first year, whether they are grown as an annual or as a perennial.

  How to Start Seeds
if you're trying it for the first time, it's helpful to read and see how seasoned gardeners approach the task, from selecting seeds to planting, maintaining, watering, and ultimately planting the young seedlings out in the garden. Visit All About Starting Seeds...
Artichoke seedlings need lots of nutrients as they develop, so fertilize them with fish emulsion or something similar. Transplant the seedlings 8 to 10 weeks later, but only after the soil has warmed and the danger of hard frost has passed. The transplants should be 8 to 10 inches tall, with stocky stems and two sets of true leaves. Because they grow quite large, they should be planted at least 4 feet apart.

Artichokes feed heavily, so, for each plant, work into the soil one cup of complete organic fertilizer or a shovel of compost or aged chicken manure just before planting. You can also apply 1⁄2 cup each of feather or blood meal and bone meal for each plant. I raise rabbits, so my plants receive a 2- to 3-inch layer of rabbit manure, on which they thrive. A midseason dressing of aged manure benefits the plants, too, if you have poor soil.

As with some other plants, particularly rhubarb, many of the artichoke plants you start from seed won’t turn out to be true to the type described on the seed packet. This happens about 20 percent of the time. I always plant extra artichokes so that I can get rid of the odd fellows and still wind up with the number of plants I want. To do this, I cull the seedlings that don’t appear to be thriving. Then I cull again at the end of the season, so I’m left with only plants that produce great-tasting chokes or show other characteristics I want to preserve.

Wide wingspan
  Artichoke has a wide wingspan; it's best to space the plants at least 4 feet apart.
I have also started artichokes with rooted shoots, but for this method, you need a neighbor or friend who has a plant to share. In the early spring, remove a rooted shoot. I do this with a long serrated knife, separating the offshoot from the remaining stems at the base of the plant. Then I cut a ring around the roots of the shoot with a spade, pushing down deeply to get beneath the roots. Ideally, I do this while the plants are still small, preferably less than 10 inches tall. Each rooted shoot can be replanted in a new location, spaced 4 to 6 feet apart.

Divide and share your artichokes
1. Separate a rooted shoot 2. Dig deeply 3. Lift the shoot 4. Replant
To divide an artichoke plant, first use a knife to cleanly separate a rooted shoot. Then dig deeply with a spade to collect the root mass for relocation. You can replant the separated shoot elsewhere in the garden or give it to a gardening friend.

You can also buy dormant artichoke roots at some nurseries. Where you live determines when you plant these. In frost-free climates, you can plant in the fall or winter. In other climates, they should be planted in the early spring, spaced the same as rooted shoots. These root shanks should be set in the ground vertically, with the growth buds just above soil surface.

Whatever your choice for starting artichokes, the plants will prosper in slightly acidic soil that is rich in organic matter. Full sun is best unless you live in an area with hot summers, then afternoon shade may prove beneficial.

Keep the planting bed moist, and water the plants as they grow. New shoots will arise from the ground each year. To encourage large, flavorful buds, remove all but one or two of the strongest shoots.

Water well for tender chokes and strong plants

The artichoke part we relish is the immature flower head of the plant, which is a member of the thistle family. There are varieties of artichokes available to suit just about every situation. For a reliable grower in cold climates, try ‘Green Globe’. This variety produces heavily and matures early enough to be grown in most areas as an annual. ‘Violetto’, an Italian variety, produces beautiful purple heads with a slightly elongated bud. It matures a bit later, however, and I have found it unsuitable as an annual. ‘Imperial Star’ was developed to be grown as an annual. Its tasty buds are round, and they mature about one week earlier than those of ‘Green Globe’.

Basket full of artichokes
  A basket full of artichokes may look like an impenetrable harvest, but cooks seeking a delicious meal see a feast. Click here for artichoke recipes from

Regardless of the variety you plant, you will want to harvest a tender crop. Many factors can affect the texture of the bud we eat, but the most important for bud tenderness is water. Artichokes need plenty of water to produce those big, succulent buds. You may need to water up to three times a week during a hot, dry spell, especially if it occurs while the buds are forming. Like too little water, an unexpected late frost can also toughen or destroy developing buds.

Water also benefits the artichoke plant’s deep roots, which are fleshy and become quite thick. They need to be kept moist, especially during the dry months. I mulch well to conserve moisture. Make sure, however, that all that water is going onto an artichoke garden patch that drains well. Poor drainage can cause the crown of the plant, where the stems sprout, to rot. In my area, it’s not the cold winter that kills the plant. Sometimes it’s the soggy soil.

Harvest an artichoke Artichoke flower
Harvest artichokes with a cut across the stem when the buds have swelled but are still firm and closed tight.   If you leave some artichoke buds on the stem, they'll flower into stunning purple thistle-like blooms.

The buds develop at the tips of 1-inch-thick stalks. The terminal bud is normally the largest and the first to mature. It should be harvested with a slice through the stem just below the bud, which should be large, firm, and tightly closed. If a few buds escape your knife, they will open into spectacular, purple-blue, 6-inch thistle­like flowers. Allowing the buds to flower, however, may reduce the plant’s vigor for the following year’s crop in perennial plantings. And you wouldn’t want that to happen with such a delicious crop.

Since artichokes like a lot of water and fertilizer I've had remarkable success with manure tea steeped in a 20 gallon plastic trash can, then feeding each plant a gallon of tea every morning.

Tea: Put in 3 or 4 shovels of bagged cow manure into an old pillow case then tie it onto a rope and hang it into the trash container filled with water. Let it steep a couple of days. For an easy dipper, cut a hole near the top of an empty ½ gal. milk jug.

FYI: The Sea Harvest Restaurant in Moss Landing, California serves a delicious pre-cored artichoke dish. Somehow they scoop out all the soft center leaves and the fuzz, then reshape it all back into its natural pyramid form. Simple to peel and so good to eat.

My plants grew huge last year, however no fruit like the year before. In the fall I had pulled out the plants !
We have also had some extreme conditions this spring. And I am in Erie county, PA. Amazing will try to save my roots this fall instead of pulling out the plants.

user-2565019 writes: The way I over-winter my artichokes follows the weatherman. You don't do anything special until a HARD frost is predicted. Light frost does nothing to artichokes and they will start regrowing afterwards.

Now, you must prepare a little bit. Have hedge clippers in hand as well as something to cover the artichokes up. I use raked dry leaves. I cut the artichokes down to about 4-6" tall. Then I coved with the tree leaves. I chop up the artichoke leaves and compost them.

In the spring, when it starts getting close to freezing at night, I start uncovering the artichokes. I keep the leaves piled like a moat surrounding the artichokes, in case I need to recover them because of a hard frost. You can also use an overturned 5 gallon bucket, but I wouldn't use it for the whole winter. They'll overheat during the day and they might start regrowing and then get bit when the temperature drops.

Last winter, I lost one plant but I still have 9 plants that have overwintered for the last three years. I live in zone 6, used to be zone 5.

I just had my first two of the season. Last year, I got over 200 artichokes. They aren't the huge ones you seen in the stores, but I cook many a lobster sized pot full of them.

congiardos writes: I have found the perfect organic solution to rid all bugs including pesty pinchers and destructive caterpillars from all my vegetable and fruit plants. Spray them with water that has had sliced serrano chilis soaking in it to create a pesticide solution. All the bugs hate this stuff and your plants will grow to be big and beautiful without using chemicals. I spray them once a week.

And I will do your recommendations for free. I have done organics for 40 years. My artichoke is doing wonderful with 20 chokes on it after heavily applying calcium last year!

AzStephani writes: Some one asked this; strawbridge5 writes: "I have pincher bugs infesting our artichokes." Any suggestions? I believe that bug has an exoskeleton, you can use DE to get rid of them. DE is Diatamaeous Earth. There is garden grade or the stuff that is used in swimming pool filters. I use both. I am not 100% sure how to use as a pesticide for plants but I would assume it is similar to extermination needs. I would (will) mix some in the soil and dust the plants with it if necessary. Wear a dust mask when doing this. Completely organic and pet safe. I wonder if it will work for aphids? Since I am growing again, I will purchase Ladybugs and Praying Mantis at the Nursery.

DanielleGardenGirl writes: Hi everyone! These are some really great artichoke questions. I’ve got a few answers to some of the inquiries below:

1. For pest-insect infestations I’m a big fan of organic treatments. My first choice is Neem, a tropical plant extract that is safe and effective. It generally comes in a concentrated spray at any garden center/nursery.

2. If you are in a warm climate where the season is coming to a close, you don’t need to do anything to your plants. Just let them die back naturally and then next spring do some maintenance pruning (remove dead, diseased, or damaged sections of the plant) to refresh.

3. For anyone still waiting for fruit at this point in the season—that is normal if you are living in a cooler locale. Here in CT we usually don’t start harvesting artichokes until late August early September.

4. As for dividing, this article includes excellent step-by-step instructions. If you’re planning on moving your mature plant, I would instead try dividing and transplanting the new shoots. Mature plants don’t relocate well.

5. Last, artichokes like a fairly neutral pH, so do a soil test and adjust accordingly.

Hope these answers help!

Livinfast1100 writes: I like the article Kris, well put together. here are answers to a few of the questions people have asked.

1. the small buds opening too soon, you need a little more rabbit fertlizer and water if they are not getting the nourishment from the soil they mature compact. they need growth promoters and water.

2. the aphid problem and you want organic.. lady bugs you can buy at the local nursery... if there are aphids the lady bugs will stay and eat the tasty bugs as their main diet. (some bgs are good bugs) or drape them with some ultra fine mosquito netting.

3. the plants growing abilities and contingent on your watering and fertlizing and the soil conditions..... but they grow fairly vigerous from a 6" plant to a 36" bloomer within a few months and grow larger if you protect them from the cold in the winter. (in utah they are on the south side of my house and over winter fine... i protect them with bales of straw as an additional plant saver.
