Overview
Rhubarb is the fleshy, edible stalks (petioles) of species and hybrids (culinary rhubarb) of Rheum in the family Polygonaceae, which are cooked and used for food. The whole plant – a herbaceous perennial growing from short, thick rhizomes – is also called rhubarb. Historically, different plants have been called "rhubarb" in English. The large, triangular leaves contain high levels of oxalic acid
Etymology
The word rhubarb is likely to have derived in the 14th century from the Old French rubarbe, which came from the Latin rheubarbarum and Greek rha barbaron, meaning 'foreign rhubarb'. The Greek physician Dioscorides used the Greek word ῥᾶ (rha), whereas Galen later used ῥῆον (rhēon), Latin rheum. These in turn derive from a Persian name for species of Rheum. The specific epithet rhaponticum, applying to one of the presumed parents of the cultivated plant, means 'rha from the region …
Cultivation
Rhubarb is grown widely, and with greenhouse production it is available throughout much of the year. It needs rainfall and an annual cold period of up to 7-9 weeks at 3°C (37°F), known as ‘cold units’, to grow well. The plant develops a substantial underground storage organ (rhubarb crowns) and this can be used for early production by transferring field-grown crowns to warm conditions. Rh…

The advocate of organic gardening Lawrence D. Hills listed his favourite rhubarb varieties for flavour as ‘Hawke's Champagne’, ‘Victoria’, ‘Timperley Early’, and ‘Early Albert’, also recommending ‘Gaskin's Perpetual’ for having the lowest level of oxalic acid, allowing it to be harvested over a much longer period of the growing season without developing excessive sourness.

Pests
