These are wonderful early bloomers in the spring and add a real punch of color to the garden. I have successfully over wintered these plants for 3 winters now by mulching heavily in the fall.

The plants I purchased in 2005 also did not survive their first winter, while I grow successfully another unidentified Primula polyantha hybrid (pink with yellow center) that thrives and blossoms like crazy in the same flower bed under trees with sun in the spring and lots of shade in the summer, lots of snow in winter. So the death of the Pacific Giant was not due to inadeqate conditions.

After blooming during the spring season, 5 to 6 planting of this cultivar dies during the winter or the second winter - if it survive the first winter it is a smaller rosette with no flowers.
