Editing Rhubarb (section)

==Cultivars==
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.<ref>Lawrence D Hills.

The Royal Horticultural Society has the UK's national collection of rhubarb that comprises 103 varieties. In 2021–2022 this was moved from southern England to the more northern garden [[RHS Garden Bridgewater|RHS Bridgewater]] where winter cold and rainfall are better suited for rhubarb.<ref name="RHS-2022">{{cite web |title=RHS Bridgwater |url=https://www.instagram.com/p/CY4AQIOqXCK/ |website=RHS Garden Bridgewater Instagram |access-date=23 January 2022}}</ref> The following cultivars have gained the [[Royal Horticultural Society]]'s [[Award of Garden Merit]]:<ref>{{cite web
