mesiangervo

Mesiangervo is the Finnish name for Spiraea, a genus of flowering plants in the family Rosaceae. This genus comprises about 80 to 100 species of deciduous shrubs native to the temperate and boreal regions of the Northern Hemisphere. Spiraea species are widely cultivated for their ornamental value, particularly for their attractive flowers, which can be white, pink, or red, and often appear in dense clusters. The name "Spiraea" is derived from the Greek word "speira," meaning coil or spiral, possibly referring to the shape of the fruit or the arrangement of the leaves.

These shrubs vary significantly in size and habit, ranging from low-growing groundcovers to taller, more upright shrubs. They typically have simple, alternate leaves, often with toothed margins. The flowering period varies by species, with some blooming in spring and others in summer. Many Spiraea species are quite hardy and adaptable, thriving in a variety of soil types and sunlight conditions, although many prefer full sun for best flowering. They are commonly used in landscaping for hedges, borders, specimen plants, and mass plantings. Several species are native to Finland, contributing to the local flora.
