Some pictures of RHS Wisley’s National Rhubarb collection in mid-April 2009. It comprised some 151 plants including a few “ornamental” rhubarbs as well as species.
You will find more about using rhubarb as a perennial vegetable in my book Around the World in 80 plants!
An album of pictures from my visit to RHS Wisley Gardens on 11th March 2019 just outside of London, one of my favourite gardens for edimental spotting which I’ve visited many times over the years. I’ve added comments of edibility to most pictures!
One of the world’s most spectacular edimentals was in flower at Mount Stewart in Northern Ireland where I was doing an edimentals walk and talk at the weekend! Related to other great edimentals like Agave and Yucca, the Mexican Lily or Patleamole is sadly not likely to be hardy in my part of the world (Yucca filamentosa is hardy though!). Beschorneria is a small genus consisting of seven species that range from the southern US, Mexico and Central America. Mexican lily’s habitat is rocky massifs and cliffs in canyons and ravines from 2600 to 3,400 masl in pine-oak and fir (Abies religiosa) forest (Ref. 1). In the same reference, it is noted that “….the flowers are edible, after being boiled and fried.”
Please let me know if you have go :)
