(aka: Silene x robotii) This one had us stumped as it was first introduced under the invalid name, Silene x robotii, only to later become a Lychnis flos-jovis. Since Lychnis flos-jovis normally has white-hairy foliage, we won't rule out a yet unnamed baby daddy. Despite one parent hailing from the central European Alps, this Gerardus Oudshoorn hybrid has thrived in our hot, humid summers. For us, the deer-resistant, drought-tolerant Lychnis 'Rolly's Favorite' forms a compact 10" tall x 18" wide basal rosette of fuzzy green leaves, covered from mid-March (NC) through summer with 15" stalks, ending in masses of 1" dark pink flowers...quite stunning!
