Great Podcast - thank you so much
I can't grow rhubarb here either and I love it. Dave, the stalk looks like celery but is pinkish/rose. You can stew it, make pies, jams, jellies, etc. I "think" the leaves are poisonous. You have to wait two years on harvesting them as well.
In addition to the YUM of asparagus, I love the fronds. It's a beautiful plant as well as delicious.
