Growing Supernova Primula Garden Seeds

Supernova primula seeds thrive in cool temperatures and best sown outside directly 4-6 weeks before the final frost. Frost and cooler temperatures will aid primula seeds in germination. For earliest blooming, start Supernova primula seeds indoors 8-10 weeks before the final frost and transplant once there are two sets of true leaves to a cool and well-shaded spot. Primula is not recommended for growing indoors since many homes do not have the cool temperatures required at night. For direct sowing, plant 2-3 Supernova primula seeds ¼ inch deep and 6 inches apart in hummus-rich, Organically fertile, and well-drained soil in partial shade. Supernova primula thrives in cool and well-shaded gardens and do not generally thrive in pots and containers. Use only a half-strength fertilizer because it can build up in the soil and cause problems. Monitor for slugs and snails on young Supernova plants and then for aphids, whiteflies, mealybugs, and other leaf eaters as plants reaches maturity. Supernova primula seeds mature in 84-91 days as 8 inch tall compact shrubs with a tidy 5-6 inch spread covered in 2 inch blooms in a mix of salmon, fuchsia, canary, indigo, magenta, ivory, and peach.

Primula x polyantha is a member of the Primulacae family and widely referred to simply as Primrose. The primula genus has been heavily cultivated and hybridized for centuries because Primrose is often one of spring's first blooming flowers.
