NIEREMBERGIA Mont Blanc (25 seeds)
Nierembergia, or cupflower, is a heat-loving, compact mounding plant that is smothered in flowers from early summer through autumn. Use Nierembergia for edging, in borders, rock gardens, or containers, including hanging baskets and window boxes
'Mont Blanc' is a profuse bloomer with brilliant white flowers on plants only 15cm high that spread to 30cm wide. The small cup-shaped flowers face upwards. It was an All-America Selection winner in 1993, and reportedly has better heat tolerance than the species.
Start Nierembergia from seed sown indoors 8-10 weeks before your date of average last frost. Barely cover the seed; it should germinate within 2-3 weeks at 70°F. Keep moist until emergence, then the plants can be kept on the dry side. Young plants grow very slowly, but grow more quickly once transplanted. Transplant outdoors 6-12 inches apart (after hardening off) just before last frost date in moist, organically rich, well-drained soil in full sun. Mulch to help retain moisture and keep the soil cool. Plants are drought tolerant once established. Stem cuttings can be taken in late summer to hold the plants over the winter.
