Growing instructions: http://www.gardenguides.com/68934-grow-evening-primrose.html

Step 1

Select an area of your garden that is sunny or partially shaded. Evening primrose enjoys a slightly acidic soil with a pH of 5.5 to 7 that is also a bit sandy. Make sure the area has good drainage.
Step 2

Rake the area where you plan to plant the seeds to loosen the soil. Evening primrose does not need to be planted deep within the soil; it just needs a light covering.
Step 3

Sow the seeds during early spring or early autumn by scattering the seeds over your prepared plot of soil. Cover the seeds lightly, about one-eighth inch, with sandy potting soil. Water the seeds in lightly.
Step 4

Water evening primrose during dry months and prune them after flowering if you'd like to avoid reseeding.
Starting from Seed Indoors

Step 1

Sow evening primrose seeds in starter pots about 10 weeks before the last frost in your area. As with outdoor planting, use a sandy soil with a slightly acidic pH level. Fill your starter pots with soil, place several seeds in each pot and cover them lightly with soil.
Step 2

Place the seeds in a dark, cool environment. Evening primrose can take up to four weeks to germinate.
Step 3

Transplant the evening primrose into your garden after the last spring frost. Plant the smaller varieties 6 inches apart and the larger varieties 20 inches apart. Water after planting.
