Wife bought a blue one last year for the first time. Plant lasted from early spring through summer/early fall in light shade (no direct sun). Lots of flower power for the money. Just bought 4 smaller ones of different colors at Wally's this year. They provide a lot of color for a long time.

When well grown, this primrose has a very long blooming period with gorgeous flowers in solid "Easter Egg" colors. Flowers colors are unusual in that many of them deepen with age, especially noticeable on the deeper violet, red, and magenta varieties. In my garden, located in an inland part of the Bay Area, I have to site these primroses carefully as they cannot take much frost (only down to the upper 20s) nor summer heat. Flower color fades if they receive too much sun. I mostly grow them in containers and treat them as winter to spring annuals, although I have had some live over for a second year. This plant is a popular florist's plant in many parts of the world. I saw many offered as such in Europe. It needs very cool growing conditions indoors.

Very pretty, fragrant. Like the drumhead primula, many flowers carried on each stem. Not frost tolerant, but likes cool conditions. Perennial usually treated as an annual. Can cause skin irritation during handling.
