Another Perfect Plant: Japanese Primrose
Japanese primroses are an easy, showy addition to any shade, wet space in your garden. Primula japonica is part of the larger section of the Primula genus called the "candelabra types." These "candelabra type" primroses are so-called because their beautiful blooms are held about 12-18" above the foliage. Native to Japan, the flowers come in a narrow range of hues from white to red. Some notable cultivates include "Miller's Crimson" and "Postford White."
Primula japonica like to be wet and perform best alongside shady streams where there is plenty of access to moisture and some afternoon shade. Given proper conditions, they will spread to form clumps and can be easily divided when necessary.
