Description
Isotope petraea is an erect, spreading, perennial or annual herbaceous plant with smooth branches that typically grows to a height of 0.2 to 0.6 metres (0.7 to 2.0 ft). The smooth leaves are narrowly egg-shaped to elliptic, 3–7.5 cm (1.2–3.0 in) long, 1–3.5 cm (0.39–1.38 in) wide, petiolate on lower sections sessile toward the branch apex, sharply lobed, unevenly spaced teeth and ending in a point. The blue-purplish flowers are borne singly on a wiry peduncle 8–25 cm (3.1–9.8 in) long. The flower petals are narrow-triangular, pointed, 5–12 mm (0.20–0.47 in) long the corolla a narrow light green tube 14–20 mm (0.55–0.79 in) long.[4]
