After burying them in a tray lined with newspaper and compost, I waited for signs of life, while deciding on a suitable sunny site. Several weeks later, 12 small plants emerged. How exciting!
The 30cm by 30cm patch I planted, bounded by concrete on the eastern side, was about a metre north of a feijoa tree planted the year before. Far too close, I was to discover!

By late summer, the leafy stems are 2 metres high. I love the sunflower-like flowers dancing in the wind and reaching for the sky.
Once flowering finishes, use shears to cut the stems close to the ground, then chop them up small and add to your compost bin. The thicker stems also make good kindling once dry.
Now the artichoke patch is 1m by 1m.
Harvesting begins in late March. I dig deep. Some are bigger than my fist.
By early spring, I must reduce my patch to 30cm by 30cm again. Throughout September, I take them to the WhEB for artichoke fans. They will be delighted.
If you want some to cook or grow, you might be lucky on a Wednesday this month. Phone 345 6000 to place your order.
