Cabbage, ‘Columbia’

(Brassica oleracea) Columbia is a market-worthy reselection of an old cultivar that came to us by way of Nash Huber out in Sequim, WA, who grew it by the acre. Columbia is a quick to mature, split resistant, round green cabbage showing good uniformity of gorgeous medium size, dense heads. Great summer cropper for all your slaw needs. (We formerly called this variety “Nash’s Summer Green”). OP cabbages have largely been abandoned for hybrids in the seed industry so it is always especially gratifying to be able to offer high quality varieties such as this to show what is possible.
