This is a plant that is not supposed to grow in my garden zone, but I have had it in my garden for years, it self sows, it is a biennial, the first year it is only about an inch tall, thin feathery type leaves, I have to be careful not to hoe up the seedlings, the second year it gets about 6 feet tall and blooms. At one time I had yellow ones also but have not seen a yellow bloom in years.
