Ozark Sundrop Seeds 6570. A serviceable ground cover rather than accent plant in the garden. Also known as Missouri Evening Primrose. Produces very showy, 7.5 cm (3″) wide, poppy-like, bright lemon yellow flowers on compact plants. Plants are quite showy once established and will thrive in sunny hot areas with soil that is less than ideal. Establishment and persistence is enhanced in dry, well drained soils. One of my favourite perennial plants! Hardy to Zone 4.
How to Grow
175 seed/gram. Sow indoors in a soil-less mix in January through February, germinate at 20 C (70 F) for 14- 21 days. Seeds germinate better when given a cold treatment prior to sowing. Grow on at the same temperature then transplant to the garden 30 cm (12″) apart when the danger of frost has passed. Direct seeding can also be attempted in May and again in August for flowering in the following year
