Rhubard is common in cooking or baking. It is easy to recognise with its iconic coloured stem, normally in red, pink, green and white. And its leaves grow large, like umbrellas covering stems and the soik underneath. Besides that, those leaves act like solar panels, absorbing sunlight for their root and food production.
Its leaves contain a chemical called oxalic acid, which is a poison to human and animals. But after decomposition, it can be used as compost on vegetables.
When autumn is coming, its leaves will turn yellow. By picking away those yellow leaves and stems, rhubard can retain energy in their crown, go through winter and continue food production in the next year.
Last year, we tried to seperate a crown of rhubarb into several small pieces, and put them in pots with mixture of compost and soil. A lot of them still kept growing this year, showing how strong their life could be.
Rhubarb is something more than just ‘food’ because each part of it shows its own ability, and tells stories about how nature works.
