This January we moved to NC from Lousiana. (And no I don't miss the rain, but thanks for asking.) Our neighborhood has a community garden with around 55 boxes in a beautiful location and a nice walk from my house. The boxes are rented out by the year. I signed up before we were even packed to move!
After getting my assigned location, I went to a local nursery to pick out varieties of things that would grow here. I saw "Seed Potatoes". They were little new potatoes in a netted bag. I thought what the heck, so I planted them right away, around mid-February, I believe it was. It took a few weeks for them to sprout because you bury them 4" deep. After about 3 weeks, I saw green sprouts coming out of the ground. And the plants grew nicely and in particular very quickly after rain. Finally, they flowered in early May and I waited an additional 2 weeks before digging in the dirt to see what I got.
Oh and the red onion came from our local farmer's market and the rosemary from my herb pot. Toss in olive oil, season with herbs and S&P. Roast at 375 for a little more than an hour for crispy results. Devour!
