65 day. A relative of the artichoke, cardoon is grown for it's flavorful stalks. Avorio Large Smooth is the largest of the cardoons with extra wide, ribbed leaves. It is ripe when the stalks turn ivory colored.
Most of the seeds I planted sprouted. The seeds arrived in a timely fashion. I received an e-mail that some were back ordered and would ship asap, I still received them in plenty of time to start them inside before planting season. Very pleased.
