The Japanese primrose (Primula japonica, candelabra) is about to bloom in the north-east US. Flowers all summer long.
The last garden planted by Henry Francis du Pont (1880-1969, American) at Winterthur, Delaware, was planted in a quarry with a natural spring.
The Japanese primrose populates the quarry bed beneath the shade of bushes which include azalea and the lily-of-the valley bush (Andromeda japonica).

Having admired this primrose in the Quarry Garden, the proprietor of Mt. Cuba, Hockessin, Delaware, Pamela Lammot du Pont Copeland (1906-2001, American) seeded a small area around a pond at Mt. Cuba with the same plant.
The Japanese primrose is the only non-native plant maintained at Mt. Cuba, a park and garden of flora native to the Appalachian Piedmont.

These primroses and their spectacular coronae are out of bounds to us this year.
As though there is a fear that they could infect us.
And, of course, year after year they have infected me with their delicate beauty, to my great good fortune.
