Nemesia (Nemesia Strumosa White Knight) - Use white Nemesia for edgings, in rock gardens and walls, and for borders. They're splendid container plants and make good cut flowers too. They establish easily from white Nemesia seeds, and they are eager to grow and bloom all summer long. White Nemesia plants do best in cooler regions where nights remain cool throughout summer. In hotter climates, the blooms will begin to fade as summer temperatures rise. Nemesia care includes using a liquid fertilizer every 2 - 3 weeks during the growing season. After the first flush of blooms fade by mid-summer, trim the Nemesia plant lightly for a second bloom that will remain for the rest of the season. Season: Annual USDA Zones: 3 - 7 Height: 8 - 10 inches Bloom Season: Late spring through fall Bloom Color: White Environment: Full sun
