Cauliflower seedlings
It's actually quite easy to tell the difference: to summarize the look of the leaves: the leaves of a cauliflower seedling are oval, with pointed edges and long petioles! This cauliflower is actually quite full. The; Cabbage seedlings: it is also oval but not so round, look at its picture its leaves are a little curved underneath, not very full. In fact, take a close look at their pictures to see what I said the difference is still very big, imagine cauliflower fruit is very full that leaves are also, cabbage it grows up will wrap up that the ground of the leaf is certainly curved!
