🍁 Enkianthus perulatus

Enkianthus perulatus, commonly known as White Enkianthus, is a deciduous, compact ornamental shrub native to Japan. It is prized for its neat, upright form, elegant spring flowers, and exceptional autumn colour, making it a standout choice for year-round interest in borders, woodland gardens, or as a feature plant in smaller spaces.

In late spring, Enkianthus perulatus produces clusters of bell-shaped, creamy white flowers, often tinged with green or pink, which dangle delicately from the branches in a manner similar to pieris or lily-of-the-valley. These are followed by a lush canopy of ovate, fresh green leaves, which turn brilliant shades of scarlet, crimson, and orange in autumn before falling.

With its slow-growing, rounded habit, refined texture, and seasonal colour transitions, this low-maintenance shrub is ideal for acidic soils and adds subtle elegance to Japanese-style plantings, woodland edges, or container displays in sheltered positions.
