Notes: Wallflower is a threatened species in the Netherlands and on the Dutch Red List of vascular plants. On the walls of Fort Rammekens, a sea fortress in Ritthem (province of Zeeland) that dates from 1547, more than three thousand Wallflower plants have been counted. This is about three-quarters of the entire population of Erysimum cheiri in this country.
It is said that in Great Britain the Normans introduced Erysimum cheiri by importing stones to build their castles. Nowadays Wallflower is widely cultivated in gardens in Great Britain, Belgium, the Netherlands, France and Germany. Many cultivars have been developed and these are available in shades of yellow, orange, red, maroon, purple, brown, white and cream.
