56-100 days. We mix 4 very flavorful, tender varieties together for a harvest period of about 2 months from a single sowing date. Contains Belstar, Purple Magic, Gemini, and Millennium. If the broccoli fancier makes one spring sowing and one more in late May/early June, a nearly continuous harvest of big, succulent heads will be enjoyed until fall. Thin carefully, as some varieties grow faster than others.
