Organic Seed Alliance has created a Facebook group called the Purple Sprouting Broccoli Bunch Up, to connect growers who are interested in growing, or are growing, purple sprouting broccoli. The broccoli is being grown at trial sites around Puget Sound to identify the best varieties for various regions and the best transplanting times. The purple sprouting broccoli overwinters in regions with mild winters, like the Pacific Northwest, and produces a fresh crop in late winter or early spring. According to Organic Seed Alliance, there are three maturity categories: the earliest maturing varieties generally have harvestable sprouts in late February or early March, the mid-maturity varieties come on two to three weeks later, and the latest maturing varieties follow after another two to three weeks. The group gives growers a place to connect, share experiences, and ask questions.
