A rare species with wonderful white flowers that rise above the large felty mid green foliage in late spring. Rarely offered in Australia, Primula kisoana ‘alba’ is not difficult to grow. Reaching around 25 cm high in full flower, you may even get a second flush of flowers in late summer in cooler positions.
This is a hardy primrose, the species itself will have mauve to rose coloured flowers, however this white form is sought after. The species is from Japan, Mt Kiso and is deciduous, and is sometimes called the Japanese Creeping Primrose.
How To Grow Primula kisoana = Basic Care
If you have a position in dappled shade and have ammended the soil with compost and aged manure Primula kisoana ‘alba’ will love it. We like to dig in a little coir peat as well to help retain moisture.
Remember that drainage is important for primulas, so no water logged soils. Some liquid seaweed fertilizer in spring and a top dressing of aged compost and mulch in winter will keep this desirable plant happy.
Best in a humus rich moist soil Primula kisoana ‘alba’ spread by underground runners and will actually handle little bit of a dry spell. Excellent when planted along a rock wall where it can weave its way through the rocks.
Plants are not readily available however it can be grown from seed and plants are sometimes seen for sale at collectors plant fairs and garden clubs.
