I really enjoyed talking about Crops that Wow for Lake Simcoe South Master Gardeners and Guests at their Plant, Grow, Eat event on Saturday.
I figured my anecdote about seeing dahlia tubers (as a water chestnut substitue) at a market garden would be the only mention of dahlias that day....but fellow speaker Marjorie Mason also had a picture of dahlias, and said that grated dahlia tuber can be used instead of grated zucchini to make bread...dahlia bread instead of zucchini bread.
The Lake Simcoe South Master Gardeners had a great veg basket, pictured. You'll see the black radish at top. I like it because it's a good keeper. The rapini is a great follow crop for garlic.
