9 of the Best Artichoke Cultivars to Grow at Home

So you’ve made the brilliant decision to grow your own artichokes, a unique and rewarding type of backyard vegetable.

But long before you pick your homegrown crop, you’ll want to pick the right artichoke cultivar.

And you have many options when it comes to choosing a variety.

You will want to choose one that has a low chill requirement if you have mild winters. But on the other hand, if your summers are short, you may need an early maturing variety.

Some gardeners are tight on space, and may want to select a cultivar known for its smaller stature.

Or perhaps it’s all about saving your skin with a crop of spineless plants?

And of course, if your preferences are purely aesthetic, you might prefer to choose a lovely purple variety for its ornamental value.

The following selections will provide you with a range of options, so you can make the most of this potentially perennial garden plant. Ready for a sneak peek? Here’s what’s ahead:

1. Colorado Star

As its name suggests, ‘Colorado Star’ was bred to come to maturity in regions with shorter growing seasons, such as those experienced in the Rocky Mountain State.

Unlike the standard slow-growing artichokes, this very early cultivar reaches maturity in just 75 days.

To meet this tight summer deadline, this open-pollinated variety produces shorter specimens, ranging from one to three feet in height, making it well-suited for more compact gardens.

Plants can be upright or prostrate and are spiny, with buds varying in color from purplish green to deep purple. Prostrate specimens may benefit from staking.

This variety, also called ‘Colorado Red Star,’ only needs ten days of cool weather for vernalization.

‘Colorado Star’ is perennial in USDA Hardiness Zones 7-10, and will provide a crop of six to ten heads per plant.

2. Emerald

‘Emerald’ is a productive hybrid variety that boasts excellent resistance to both cold and heat.

These thornless artichoke plants reach five feet tall, with bright green buds that are five inches in diameter at maturity.

According to Joseph Masabni at the Texas A&M Extension, this variety requires little to no vernalization, so it’s well-suited to warmer growing zones.

‘Emerald’ needs 180 days to produce a harvest and is very productive – you can expect up to twelve buds per plant.

You can purchase packs of ‘Emerald’ from Ferry Morse, available via The Home Depot.

3. Green Globe Improved

‘Green Globe Improved’ is a more refined variety of the old heirloom ‘Green Globe’ artichoke.

Compared to ‘Green Globe,’ this improved variety has fewer spines, is more productive, and plants are more uniform in size. However, it is a bit slower to reach maturity than ‘Green Globe.’

‘Green Globe Improved’ grows to be five feet tall, and four to eight feet wide.

Expect three to five buds per plant in the first year, and more in subsequent years for perennials.

4. Imperial Star

‘Imperial Star’ is an artichoke cultivar that provides an early harvest of sweet, mild buds in the first year of growth.

This shorter season, open-pollinated variety produces nearly spineless, green-colored buds that are ready to harvest 85 to 90 days after transplanting.

‘Imperial Star’ plants are on the smaller side, growing to be one and a half to four feet tall, a more manageable size for container gardening.

This cultivar has good disease resistance and tolerates light frosts, but unless you’re in USDA Hardiness Zone 7 or someplace warmer, it should be grown as an annual.

This open-pollinated cultivar shows good tolerance to both heat and cold.

‘Purple Italian Globe’ produces a harvest of six to eight tender and delicious buds, measuring three to six inches in diameter at harvest time.

‘Tavor’ is an early-maturing variety with a low chill requirement, permitting many gardeners to enjoy a harvest in a single growing season.

Heads are green with purple tips, and measure four and a half inches across when they’re ready to pick.

Also called ‘Tavor Imperial Star,’ these open-pollinated plants are two to four feet tall, have an open growth habit, and are nearly spineless.

This cultivar is a perennial in USDA Hardiness Zones 7 and up, with improved cold tolerance.

8. Violet de Provence

‘Violet de Provence’ is an early, productive heirloom from the South of France that is well-adapted to warm climates.

This open-pollinated artichoke, whose name means “purple from Provence,” is a rare find outside of Europe.

‘Violet de Provence’ has purple, elongated buds, and tightly closed bracts.

The buds of this cultivar are best picked when they are very small – when they’re just one to two inches wide – and enjoyed as baby artichokes. At this size they are extremely tender, and can be eaten raw.

‘Violet de Provence’ plants grow to be 30 to 40 inches tall. Perennialized, they will produce for several years.

‘Violetta di Chioggia’ is an heirloom variety that comes from the Veneto region of Northern Italy.

Does Chioggia sound familiar?

In addition to ‘Violetta di Chioggia,’ the town of Chioggia is known for a few other heirloom vegetable varieties as well, including a beautiful beet variety that reveals concentric pink and white rings when sliced horizontally.

Also known as ‘Violetto di Chioggia,’ this shorter season artichoke is loved for its purple, slightly elongated buds.

More cold tolerant than the most common cultivar ‘Green Globe,’ ‘Violetta di Chioggia’ is hardy to Zone 6, and requires 120 days to reach maturity.

These heirloom plants produce six to eight buds each.

With these choices, you should be all set for a successful season of artichoke growing – and a satisfying harvest.

Choose a cultivar that is well-adapted to your climate, consider the size of the mature plant, and of course, let your sense of whimsy guide you to that lovely heirloom or purple variety!

Kristina Hicks-Hamblin, thank you for the growing information and size of so many varieties of artichoke. But my #1 interest is FLAVOR, and many of the modern/thornless varieties are lacking!! I expect to find wimpy taste in the supermarket, but not from my garden! I would love to grow the smallish, spiny, tough BUT richly-flavored artichokes that we grew in my childhood on the western edge of the Mojave desert, USDA Zone 8b –which is similar to my inland Mendocino County area, CA.
