Every time I have grown cilantro, the roots are absolutely puny in
comparison to the whole plant. Right now I have a large patch, and
would be lucky to have a sturdy 1 or 2 inch long taproot for a 15-inch
high, bushy plant. I'm growing Santo, which is a bolt-resistant
variety. Does Thai cilanto generally have more substantial roots? The
amount of leafy cilantro I'd have to harvest in order to accumulate,
for example, a tablespoon of cilanto root boggles the mind.
