Although the brownish color may not look pretty, "Frost Kissed" artichokes taste delicious and actually have a more intense flavor than green, "Frost Free" artichokes. Frost conditions enhance the flavor of the artichoke causing a nutty taste. Once cooked, the peeling disappears and leaves a delicious, green artichoke.
Artichokes are "Frost Kissed" when the temperature drops below 32 degrees. Following a freeze, artichoke plants take two to three weeks to start producing "Frost Free" artichokes again.
