Thats awesome they grow all year around where you live. We grow them from spring to fall here and then restart next spring.
Those leaves do look a little different than mine, so maybe its a different cultivar.
What color are the spuds? Mine are red on the outside and yellow on the inside.
Hah I am sure they will taste good, I have eaten alot of the leaves raw and seems just like some stringy lettuce to me.
