I've always read that celery is very difficult, so I've never seriously tried celery. I've tried the dwarf "gold" variety which is recommended in books, it grew, but all I got was a multicluster of tough chewy small stalks that were pretty much inedible.
I tried some 'Tango' transplants for fun this year... grew easily and is the best celery I've ever eaten, a great snack.
Is 'Tango' really that good? Or did I just get lucky?
