We planted some seeds under the grow lamp on the 8th of March, and they seem to be getting on well. 15 days later and this is what we have.
The ones with two large leaves are artichokes. I am really hopeful that by the end of the season they will be big enough to plant up in our per meant area next to the poly tunnel. We won’t be able to harvest them for the first few years while they establish, but after that they should give us artichoke hearts and leaves every year.
