Primula x polyantha & Primula acaulis
The Common English Primrose Flower
Primula x polyantha is a cross between Primula acaulis (the common English primrose flower) and P. veris (the cowslip). Primrose plants bloom during winter and spring.
Although primroses are perennial, it is best to grow new plants each year.
The pink, purple or red blooms often have a yellow or white eye.
The bright blooms appear in clusters held just above the 3 inch long, textured green leaves.
There are single and double primrose flowers.*
The 6-12 inch tall plants love cool temps (60-65 degrees F.)and are not suitable for use as houseplants unless they are to be kept on an unheated porch or in a cool greenhouse.
Primula x polyantha plants are technically hardy from zones 3-8 but they may fail to return where it gets too hot. For most gardeners, it makes more sense to treat them like annuals.
If primroses come back year after year in your yard, you can increase your collection by digging up and dividing the clumps.
If you don't want to risk digging up your primrose perennials, dig a small plant out from around the edge and start a new clump with that.
*Double Primula varieties are older than the singles and perennialize more reliably.
Growing Primrose Plants from Seed
Primula x polyantha seed is tiny and does not always germinate quickly. Sprinkle the seeds evenly over the surface of moist potting mix. Press them in gently.
Keep the seed flat moist and cool. 60 degrees F. is optimal--no warmer. Some gardeners find that the easiest thing to do is sow seed in the fall and leave the flat outside (covered with burlap) all winter. The seedlings will come up in the spring. Transplant the new plants into individual pots once they have 3-5 leaves.
Once they have put on some size, plant the seedlings out into moist soil to which you have added plenty of compost. Site the bed in part shade.
Slugs love to dine on primrose leaves so spread so slug bait around the seedlings to keep the pests off.
What is Primrose Herb?
This is an herbal remedy made from Primula versis or P. officinalis whose edible leaves have traditionally been used as a salad green.
It is sedative, antispasmodic and anti-inflammatory. In medieval times, cowslip was used to treat coughing, nervous conditions, anxiety, arthritis and back pain.
