Rich, butter-yellow blooms peeking out of a chocolate mottled throat. This vine is one of the rarest of its kind, capturing gardeners attention everywhere. The cultivation of Aristolochias is undemanding. Sun lovers that appreciate some shade in hotter inland areas, they adapt to any soil that drains well. Any pruning necessary to contain or shape the plants should be done in late winter or early spring. Cultivation is easy, and growth can be tamed.
