About

The Giant rhubarb is very big so think about the space you have before planting it. It’s very hardy, likes the sun but can withstand the winter freeze down to -5%. Schedule 3 of the EU (Birds and Natural Habitats) Regulations 2011 in the Republic of Ireland as an invasive non-native species. This won’t stop you buying it if you're from there but you should take care of any garden waste it produces properly.
