One of our summer blooming primroses, Primula vialii, is also one of the most captivating ones grown at the Jensen-Olson Arboretum in the national Primula collection, recognized by the North American Plant Collections Consortium.
The unmistakable flower spikes resemble miniature bottle brushes. The buds are bright, scarlet red while the flowers themselves open to soft lavender.
To be successfully grown, they require a moist, but well-drained, humus-rich soil. Their crowns die completely down in the fall and it is one of the last plants to emerge in the spring. This necessitates marking the crowns so that spring gardening activities do not harm the new shoots before they begin growing.
