My artichoke is completing it's second season with astonishing results. It was purchased in March of '11 and had three leaves, two of which died right away. By May there was a tiny bud beginning to appear.
It wasn't till the end of August that the seeds would be released. I thought they would have millions like a dandelion but most had about 5 seeds. I guess the bees didn't do such a good job this year.
In a matter of a few short weeks (mid September) it has already put on tons of new growth for this winter.
