Hi All, I am interested in trying to grow some tree collards in my greenhouse. I would like to find a source of cuttings here in BC so that I can get a few started. Tree collards are perennials which, apparently, rarely set seed. They can stand a few degrees of frost, but perhaps not as much as we can get on the coast. They grow well outside in the southern US and in California. They can easily grow to over 6 feet tall and bear a nice crop of leaves year around. They can stand some shade in the summer. This is why I thought they might do well in my grape house. Shade in the summer, sun in the winter, plus they would have protection from the wind. I would hate to see what a gale wind would do with a 6 foot tall collard plant! If anyone knows where I could get a start or two, I would love to find out. Cheers!
