|FOR THE GREENHOUSE OR COLD WINDOWSILL ONLY, PRIMULA OBCONICA CANNOT SURVIVE OUTDOORS IN ZONES 9 OR LOWER. I HAVE ALWAYS LOVED P. OBCONICA, BUT THEY ARE HARD TO FIND TODAY. THEY ARE BEST AS A SHORT-LIVED POT PLANT FOR THE COOL MONTHS.|
With the advent of spring, comes primroses - but there are many species available, and although most are cold-growing, many people struggle with keeping primroses in the garden. Later next month, I will review the various types available, and their culture, for you might be surprised that they are not a difficult to grow and one may believe, for now, I share this weeks chores with some of the primula species I keep.

In the garden, or specifically, in the alpine troughs, high-elevation primula are awakening. Some require a little care, particularly the highest alpine forms of P. auricula and P. marginata, which tend to develop wood stems with a tuft of leaves at the end. These are plants designed to grow in tight, mountain crevices and screes, where tiny gravel and rock chips break off of the highest peaks, and tumble down into the crevice, filling in a sort-of natural mulch all year long. Scree plants often grow in gardened at low elevations with these long, bare stems, since tumbling rocks rarely exist in the home garden. So a little ingenuity is required ( arriving as a bucket of sharp gravel). I apply a new layer to my scree garden plants every spring, placing gravel chips of granite around the plants until only their leaves are left showing. This works well with Primula marginata, which could also be dug and planted deeper every year too as an option.
