These two Lychnis have a very similar growth habit, with an airy cloud of tufted double blooms hanging like a mobile. ‘Petite Henry’ is the white version, and ‘Petite Jenny’ is the pink one. Importantly, these are dwarf versions of Lychnis, so the puffy blossoms are held on thin, wiry stems about a foot above the plant. Each cultivars has a long life in the vase. Flowers are sterile, so the plant generates blooms for a long time, from about May to October.
