Primula x polyantha, also known as “Primrose Flower,” is a tough perennial flowering plant in the Primulaceae family. It sprouts deep green leaves with crinkled edges. Primroses bloom during spring and last through summer, producing flowers with colors ranging from red, orange, and pink to white, cream, and light yellow.
Mostly grown as an outdoor plant, primrose flowers are great for use as border plants. Primroses are finicky when it comes to indoor cultivation, as they mostly do not survive for long after the blooming period is over. The best way to preserve your primrose house plants will be by transferring them and planting them outside after the blooming season is over.
Primrose is native to parts of Africa, Europe, and Asia. Under the right growing conditions, primrose can reach a height of 6 to 20 inches and a spread of 8 to 20 inches.
The raw leaves of primrose are considered toxic to both pets and humans. It is advisable to always use protective coverings such as gloves when handling its leaves as they cause irritation.

Primrose Flower Care
Primroses are considered short-lived plants when grown indoors.
Growing and caring for the primrose flower as an indoor plant can be challenging. This is because the plant dies off after the flowering season is over.
But with the right growing conditions, you can extend the life of the plant.
Primroses grown indoors require a daily supply of bright, indirect, or filtered sunlight. Avoid exposing the plant to direct sunlight to prevent wilting. Place your primrose close to an east-facing window so it can receive the weak early morning sunlight.
For outdoor growth, ensure your primrose is located in a shaded area. The plant can withstand both partial to full shade, provided it is in a bright location.
The primrose plant loves a nutrient-rich potting mix that’s capable of draining fast and, at the same time, remaining moist. Avoid soggy soil as primrose roots are susceptible to root rot.
When growing in pots indoors, make a potting mix using part soil, part perlite, and part peat moss to create a well-draining soil. Also, add organic compost to the pot to help increase soil acidity.
For outdoor cultivation, always ensure the soil is kept moist.
Provide your primrose plant with just enough water to keep the soil moist. Waterlogged soil can cause root rot and wilt.
Do not over or underwater your primrose plant, irrespective of whether it is being grown indoors or outdoors.
For those grown in pots, make drainage holes underneath the pot to help drain out excess water.
Feed your primrose plants using a well-balanced fertilizer or manure. For indoor growth, apply the diluted fertilizer once a month during the growing season.
For outdoor growth, use a well-balanced fertilizer such as 10-10-10 and apply it at the base of the plant.
You can also use diluted organic manure such as cow dung or mustard cake to feed the plant.
Temperature And Humidity
The primrose grows better in a warm and humid environment. The ideal temperature for growing this plant is around 50–65 degrees Fahrenheit (10–18 degrees Celsius).
Higher temperatures can cause wilting, so ensure you move the plant indoors when the summer heat becomes too much.
The primrose loves humidity, so try to maintain a humid environment for your plant. Place the plant on a pebble tray to help boost its humidity level.
Carry out deadheading by pinching off dead and faded flowers from the primrose plant. This will help the plant focus all its new energy on growing new leaves other than flowers.
Clean up your primrose plant by cutting off any old and dead stems or leaves from the plant. You can also prune primroses to your desired size by cutting off unwanted or extra long stems.
Propagating through root division is easy and faster compared to other methods like seeds.
The first step involves getting a primrose plant, preferably one that’s done with flowering. Completely remove the plant from its pot.
Remove every bit of soil from the roof of the plant. Divide the root into parts and plant each individual part in a separate pot.
Water the plant, and after a few weeks, it should start producing leaves.
Common Health Problems/Pests And Diseases
Primroses grown outdoors are less likely to be attacked by pests compared to those indoors.
Common pests affecting this plant include aphids, leafminers, mealybugs, and spider mites. This pest can be controlled by spraying insecticidal soaps on the plant’s leaves.
Common health problems include root rot caused by overwatering and leaf wilting caused by either excessive sunlight or underwatering.
