Tropaeolum leptophyllum

Quick Characteristics:

Tropaeolum leptophyllum G.Don is a species from Chile (around region V). It is said to be closely related to Tropaeolum polyphyllum. Some sources state both hybridize, but unlike that species, it is a true climber. The shoots appear in early spring, and soon after flowering in late spring or early summer, they go back into dormancy. The bright yellow flowers have a fine pattern of red lines on the upper petals.

Pictures by Martin Bohnet show a plant cultivated in a container together with Buddleja globosa, which shares the same geographic origin. Since that species survives planted out in southern Germany, chances are Tropaeolum leptophyllum would also, as the deep digging tubers don't really like to be pot bound.
