One of the biggest problems with passionflower is the fungus that causes fusarium wilt. Fusarium wilt is a soil-borne disease that can be fatal. The first signs are yellowing of the leaves, followed by dieback and leaf drop. After this, the branches and trunks split and pull away from the bark. Finally, the roots discolor and die. Again, growing passionflower vines on a yellow-fruited subspecies rootstock helps control this problem. Viruses, like cucumber mosaic, can affect passionflower. It is usually transmitted by cucumber beetles and aphids. The virus can also be spread between plants or by infected seeds.
