One of our earliest blooms of the growing season is Giant Imperial Larkspur! Early spring pollinators love the striking deep purple, pink, and white flower spikes that bloom right until the heat of the summer begins. Seeds are easily saved for the next season after they have dried on the plant. We like to start these seeds 6-8 weeks before our last frost date indoors under simple grow lights. Seedlings are surprisingly cold hardy!
