Heliotrope Plant Fungus
Heliotropium arborescens, the summer annual that blooms in shades of purple and blue, is resistant to many diseases including fungus. Yet, common heliotrope or heliotropium europaeum can be a noxious weed and can be kept under control by introducing a rust fungus. And garden heliotrope , also known as valerian, is susceptible to white mold. Does this Spark an idea?

Blue Heliotrope
-
Heliotropium arborescens is a fragrant addition to your garden and one that blooms in shades of blue and purple. The scent of vanilla comes from the flowers. This plant prefers full sun in the morning and afternoon shade, especially in the heat of summer. It's deer resistant and also resistant to pests and disease.
Common Heliotrope
-
Common heliotrope is a weed that is toxic to cattle and is a widespread problem in Australia. Unlike blue heliotrope, the flowers of the common heliotrope are white with yellow throats. In order to combat this variety of heliotrope, the Australian government has introduced a rust fungus with the hope that it will control the spread of common heliotrope.

Garden Heliotrope
-
Garden heliotrope or valerian is sensitive to white mold. This mold is caused by a fungus called Sclerotinia sclerotiorum and rots plants quickly. This fungus spreads through a garden bed when weather is moist and cool with little to no air circulation among plants.
