Spiraea japonica Fenna - Japanese Spiraea

Japanese spirea or Spiraea japonica 'Fenna' is a dwarf variety that is particularly compact, very robust, and resistant to mildew. Its healthy, medium green foliage is enriched from May to August with a dark pink flowering that does not fade for several weeks. 'Fenna' attracts more pollinators than most spireas. It naturally has a compact, round, and neat shape and prefers a sunny exposure, although it tolerates partial shade.

'Fenna' Japanese spirea, from the rose family, is a cultivar derived from Spirea japonica (synonym Spiraea x bumalda or Spiraea callosa), native to eastern and central China and Japan. The growth of this plant is moderate, and its adult size will not exceed 25 to 30 cm in height and 30 cm in width. Forming a true well-rounded mound, supported by dense and branching vegetation, this variety develops young foliage tinged with bronze that unfolds into small, light and vibrant green leaves, darkening somewhat in summer. This foliage consists of small, oblong and toothed leaves. The particularly numerous flowers are grouped in terminal corymbs measuring 5 cm in diameter, with a velvety appearance and a dark pink colour. This prolonged flowering attracts numerous butterflies, bees, and bumblebees.

Japanese spirea adapts to all climates and soils, but dislikes scorching or overly arid conditions. With its beautiful cushion-like habit and small size, 'Fenna' is ideal in a pot on a balcony or terrace, as well as in the garden, as a border or foreground plant in flower beds. Use it as a ground cover along a pathway or even in a rock garden. Pair it with dwarf roses, with Potentilla fruticosa 'Double Punch Pastel', in front of miniature shrubs like the Dwarf Manchurian Lilac 'Miss Kim' or Weigela 'Nana Purpurea'. Also accompany it with other spireas (Spiraea betulifolia), the Purple Willow, Salix purpurea 'Nana'.
