When you see rainbow shades of bright primroses gracing the front of your neighborhood garden center, you'll know that spring is just around the corner. Primroses are often planted among other early spring-growing plants like crocuses and daffodils, but most people don't think about growing them indoors. Like primroses growing in the outdoor landscape, they require little maintenance and bring with them a splash of springtime color.
Purchase a healthy primrose at a nursery or garden center. Leave the primrose in the original container or transplant it to a more decorative container, if you prefer.
Put the primrose in a cool place where the temperature doesn't rise above 65 degrees during the daytime and 55 degrees at night. The primrose needs indirect light and should only be put in a sunny window on cool mornings.
Keep the soil moist and provide plenty of humidity, especially if the room is warm. This can be done by misting the plant lightly.
Discard the primrose when it's finished blooming, since primroses are seasonal plants. If you want to try saving it, you can continue to water the plant until the leaves die down, and then trim them off. Move the plant to a cool place and plant it outside the following spring. If you are lucky, it might bloom a second year.
