Broccoli has a long culinary history going back to the Romans. The florets, leaves, and stems are packed with vitamin C and provide calcium, potassium, and iron. The 4"-6", blue-green heads are delicious raw or cooked. 'Waltham 29' grows prolific side shoots and is specially adapted for cold tolerance. Freezes well. Kids will delight in the "little trees" on their plate.

I planted these seeds directly into my raised beds in the middle of December in SoCal/9B. They took awhile to germinate, but really took off when we got a good week of sunshine. They are all 5"-6" tall and they all germinated. They seem to be doing really well in the winter. This is my first time growing these in the winter from seed. Very happy with how they turned out, can't wait to taste them later.
