Primroses give a bright splash of bold color both indoors and out. These popular perennials are characterized by colorful booms and mounding clumps of fuzzy leaves, and make an excellent addition to garden spaces or containers.
Primroses come in a variety of vibrant and vivid colors including white, yellow, red, purple, pink, orange, blue and more; ocasionally there will be multiple colors within the same plant. They are well suited to a variety of garden situations and can be used to compliment spring blooming bulbs, in exciting container arrangements, as a natural ground cover for ornamental garden trees, or to provide a bright spot of color to a shady garden area.
Primroses tend to act as a hardy perennial in Zone 7 and up; if planted in Zone 6 or under, they should be in a protected area. They begin blooming in late winter or early spring and can have flowers lasting until early summer. They grow best in slightly acidic soil and prefer cooler temperatures with low humidity, and are happiest in a shade or partial shade setting. Summer heat can cause primrose foliage to fade but pruning and watering will see the leaves return full force in autumn. Relatively small plants, they do not usually exceed 8 iches in either height or width. Primroses don’t have serious pest or disease problems; however, like many shade plants, slugs and snails can sometimes be a minor nuisance. Propagation occurs naturally - primrose plants spread slowly by rhizomes in the ground. Simply divide primroses in the late spring after flowering is complete.
As with outdoor primroses, blooms begin in late winter and early spring. When kept indoors, primrose blooms will typically last up to one month. Indoor primroses do best in bright, diffused light and out of direct sun. Moderately moist soil is preferred; to acheive this, water thoroughly when just the soil surface gets dry to the touch, making sure not to let the plants stand in water or dry out. Primroses like cool temperatures, ranging from 60 to 65 degrees during the day and 55 to 60 degrees during the night. A fertilizer like Espoma is recommended, to be applied following the written instructions. As one of the first flowering plants of the year, primroses are a great way to brighten up indoor spaces while waiting for spring to arrive.
