We’ve been eating dandelions for lunch every day now for almost 3 months from the roots dug in the autumn and there’s still loads (see my post in January and February here: https://www.edimentals.com/blog/?p=27183 and https://www.edimentals.com/blog/?p=27343). We basically cut at the base with scissors and yesterday accidentally dissected a flower bud! The dandelions will respond with new leaf and flower shoots. Forcing pots of dandelions and other perennial vegetables in the living room; ease of access in what permaculturists call Zone 0
