Primrose flowers provide a beautiful splash of color to gardens, ranging from yellow, red, pink, white and purple. They bloom from early to mid-spring, and are usually the first blooms to pop up. They won't bloom the first year, but will be hardy the second year if cared for properly.
Plant primrose's tiny seeds in a seed tray in between sterile soil and damp peat moss. To encourage growth, place the tray in the freezer for three weeks to simulate the winter that flower seeds go through. After the three weeks, keep the seed tray at around 70 degrees F for about a month, or until the seeds begin to germinate. After they sprout and are about 2 to 3 inches tall, transplant them to planter pots.
Keep the primrose in a shaded area where they can stay moist. They are great to plant under other plants where filtered light can come through, in slightly acidic, rich soil.
Grow the primrose flowers strong with a mixture of compost, soil and water packed in around the roots. Once they are established, they are easy to maintain and will bloom with little attention all summer. In the winter, they can survive on their own outside while being dormant, and it is not necessary to mulch or protect them during this time.
Water your primrose flowers well regularly, especially during dry weather or environments. Keep in mind that the soil needs to be moist constantly. Primrose thrive on composty, woody, moldy areas because of the rich nutrients.
