This gourmet-quality perennial is grown in warm climates as either a perennial or biennial, however it is grown as an annual in colder climates. Native to the Mediterranean, Artichokes are becomming increasingly popular in many gardens from Zone 11 north to Zone 4.
In North America, the ideal climate for growing Artichokes is
along the coastal areas of central California, where the plants yield all year long. You will just need to give some special attention if you live in any other region, gardeners from many regions enjoy growing these and are certainly worth it.One medium artichoke will pack a real punch of dietary fiber as well as eating the leaves and heart will also serve up a good amount of the required daily value of vitamin C, K and folate. Did you know that a recent study ranked artichokes extremely high in total antioxidants per serving, out of more than 1000 foods that were tested. Artichokes even outranked the highly proclaimed broccoli.
Vegetable Garden - Tips on Growing Artichoke From Seeds
The objective is to convince the Artichoke plant that it is two years old and ready to make buds, rather than a seedling ready to make only leaves. This is done by growing the plant at cool temperatures for a prescribed length of time. This cold treatment makes the seedling behave as if it is an older plant ready to flower.
Before you use the cold treatment here is information for sowing the seed.
Sowing the Artichoke Seeds
- Artichoke Seed Depth: ¼" (6mm)
- Germination soil temperature: 70-80ºF (21-27ºC)
- Days to Germination: 10-14
- Late winter to early spring- 10 weeks before last frost.
Sow outdoors: Not recommended.
Growing Artichoke Seeds:
Temperatures during the cold treatment should remain below 50° F (10° C) but above 35°F (2° C) for at least 250 continuous hours (about 10½ days). Since it is difficult to prevent times when temperatures rise above 50° F (10° C) give the plant the cold treatment for an even longer period, let's say from four to six weeks.
- pH range: 6.5 - 8.0
- Growing soil temperature: 60-75ºF (16-24ºC)
- Spacing in beds: 24" (60 cm)
- Watering: Heavy
- Light: 8 hours or more per day
- Nutrient requirements: N=high, P=high, K=high
Put the plants in a cold frame about six weeks before the last frost based on your location and zone. When all danger of frost is past and the soil temperature is above 60ºF (16ºC) set plants about 2 feet apart in the bed.
