Primrose Care Primroses give a bright splash of bold color and are most commonly used as houseplants, a garden plant in containers or in hanging baskets. Primroses come in a variety of vibrant and vivid colors including white, yellow, red, purple, pink, orange, blue and more, even a mixture of the colors. The botanical and common name is Primula. Primroses tend to act as a hardy perennial in Zone 7; if planted in Zone 6 or under, they should be in a protected area. They bloom early to late spring and typically have blooms lasting up to one month indoors. Its green, fuzzy looking leaves form in pleasing clumps that serve to show off the primrose flowers beautifully. They are relatively small plants usually not growing over 8 inches in height or wide. A bright-diffused light indoors is best, out of direct sun. Moderately moist soil is preferred; to acheive this, water thoroughly when just the soil surface gets dry to the touch. Do not let the plants stand in water or dry out. Primroses like cool temperatures, 60 to 65 degrees during the day and 55 to 60 degrees during the night. Summer heat can cause primrose foliage to fade but pruning and watering will see the leaves return full force in autumn. They grow best in slightly acidic soil and very hot or humid weather is not tolerated well.An organic fertilizer like Nature’s Creation is recommended, use as instructed on the bottle. Primroses are easy to maintain and naturalize well when conditions suit them. Primroses don’t have serious pest or disease problems although like many shade plants, slugs and snails can sometimes be a minor nuisance. Propagation occurs naturally as primrose plants spread slowly by rhizomes in the ground. Simply divide primroses in the late spring after flowering is complete if desired. Primroses have their best season in early spring as one of the first flowering plants of the year. 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.
