* Will self-seed and spread. There are quite a few varieties, including some that are intended to be grown as annuals, so check with your local Extension office to ensure you select one that will perform well in your Zone. Start seeds indoors 6-8 weeks before average last frost date or outdoors as soon as the soil can be worked in the spring. Transplant seedlings after the threat of frost has passed.
