O. Bolòs et J. Vigoe distinguish Convolvulus tricolor ssp. pentapetaloides (L.) O.Bolòs & Vigo, found in the Balearic isles, from the type subspecies (Convolvulus tricolor ssp tricolor) by flowers that are smaller (7–10 mm), and both the calyx and the capsule having few or no hairs.[4]

Common on cultivated land, dry open habitats, sandy places and roadsides. Soil must be warmed to at least 64 °F to grow without any issues.

This flowering plant is native to the Mediterranean Basin, particularly the south, but it is occasionally seen in other areas of similar climate. In Spain it can be found in the Balearic Islands,[4] and Andalusia, especially in the Costa del Sol.[5]

Convolvulus tricolor is usually cultivated for ornamental purposes. The species[6] and the cultivar 'Blue Ensign'[7] have both received the Royal Horticultural Society's Award of Garden Merit.
