Suurtetõruõis

Suurtetõruõis is the Estonian name for the flower of the greater bindweed plant, Convolvulus sepium. This species is a common climbing or trailing herbaceous perennial plant belonging to the morning glory family. The flower itself is typically trumpet-shaped, large, and prominent, often with a white or pale pink color. The petals are fused to form a funnel or cone shape. Suurtetõruõis opens in the morning, hence the common association with morning glories, and usually closes by the afternoon.

The plant is characterized by its vigorous growth habit, with vines that can reach several meters in length. It is found in a wide range of habitats, including hedgerows, fields, gardens, and roadsides, often considered a weed due to its invasive potential. The leaves of the greater bindweed are typically arrow-shaped or triangular. The flower of suurtetõruõis, while attractive, is ephemeral, blooming for a single day before wilting. Despite its temporary bloom, the profusion of flowers throughout the summer can make the plant a noticeable feature in its environment. The root system of the greater bindweed is extensive, contributing to its resilience and ability to spread.
