About Tropaeolum peregrinum L.
Tropaeolum peregrinum L. is a climbing plant that reaches 2.5 meters in height by scrambling over other vegetation. Its leaves are 2–5 cm in diameter, palmately lobed, with three to seven lobes (most often five). The leaves are subpeltate: the leaf stalk attaches within the leaf blade, not at the edge, but close to the edge. The flowers are 2–4 cm in diameter, with five frilled petals. Petals are bright pale yellow, matching the color of canaries, which gives the species its common English name; petals often have red spots at their base. Each flower has eight stamens and a 12 mm nectar spur at the rear. In cultivation, it is a frost-tender perennial that is widely grown as an annual ornamental plant in cool temperate regions around the world.
