White Knight Nemesia Seeds

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.

How to grow Nemesia from flower seed: Sow Nemesia seeds indoors 4 – 6 weeks before last frost. Sow flower seed on surface of starter compost and gently firm down compost, only lightly cover. Keep soil damp but not wet. Do not exclude light. When the Nemesia seedlings are large enough to handle, transplant into 3 inch pots and grow in cooler conditions. Gradually acclimatize the young Nemesia seedlings to outdoor conditions. As seedlings grow, pinch back 1 – 2 times to encourage compact growth. Transplant outdoors after all risk of frost has passed, 6 inches apart. Or directly sow Nemesia seeds outdoors in prepared beds when danger of frost has passed. Thin to 6 inches apart.
