Spring planting delayed

It finally feels like Spring and most greens should be planted right now, if not before. I have procrastinated because it felt like it was going to stay cold permanently. The ground was still frozen solid in mid March, when greens can normally be planted in this region.
But here it is, a full week into April. Lettuce, parsley, Swiss chard, kale, spinach could already be coming up.
I have one thing in my favor, my fall garden has turned into an early spring garden. I left the cold frame covered all winter and removed the plastic wrap today to behold spinach plants, in good shape.
Other veggies that can be planted now include onions, radishes, beets, carrots, potatoes, peas, broccoli, cahliflower, cabbage and Brussels sprouts.
