‘Imperial Star’ is an excellent variety to grow as an annual, and produces a good crop the first year. Buds are spineless, 3-4 inches across, and glossy green. When starting from seed, do everything you can to induce rapid growth in the plants, because in the end it will result in a bigger harvest. Start seeds inside between February and March, and transplant out in 8 weeks, after the soil has warmed and there is no danger of frost. 20% of the plants will probably not produce flowers, so cull the smaller ones on transplanting. To harvest: cut the flowers before they begin to open.Important Info : Fleshy flowers are the edible portion of artichokes.
