This new oenothera hybrid was given the illegitimate name O. 'Innoeno131', so we have adopted their illegal trademark name of O. 'Lemon Drop' as the first properly published cultivar name. This new hybrid from Germany's Innovaplant is a cross of the plant we used to know as calylophus...before the taxonomists got hold of it. This new selection makes an 18" wide clump of woody stems, clothed in narrow green leaves and topped from May to September with a continuous show of round, bright yellow flowers. O. 'Lemon Drop' is a superb plant for the dry rock garden. Pot size: 24 fl. oz (709.77 ml)
Zone: 6-8, possibly colder
