The petals of the Houndstongue (Cynoglossum officinale) are pink to red in color at first, but do not fade as they wither, instead turning dark purple. Other members of the Boraginaceae family do the same, such as forget-me-nots.
Other common names are Houndstooth, Dog’s Tongue or Gypsy Flower.
The flowering time of Cynoglossum officinale here in Central Europe can last from April to July. It grows biennially, in the first year only a rosette leaf appears, from which a flowering shoot grows after overwintering.
Houndstongue can be found along roadsides, on playgrounds and sports fields, in meadows, on dams, embankments, as well as in rubble areas. How tall it grows depends on the location. In nutrient-rich soil, it can reach up to one meter in height.
