Purple Romagna Artichoke Plant & Seeds: Stratify seeds by putting them in sand for 2 weeks in the fridge, then start seeds indoors 2-3 months before last frost; plant them 1/2" deep, in 4" pots. Keep the seedlings at a temperature of 60-70 degrees. Once they grow several leaves, expose them to temperatures lower than 50 degrees F for at 12-20 days; this process, called vernalization, acts as a false "winter" that speeds the growing process. Transplant the seedlings outside two weeks after the last spring frost. Space them 3' apart in rows 5' apart. Direct sowing the seeds outside after last frost also is an option, though it takes the plants longer to mature and usually means your first crop will be in the spring. Direct sow the seeds about 3' apart, ½” under soil surface, and water. Artichokes can also be fall planted, especially in warmer climates, since artichokes thrive in cool weather.
