I've been told that tiger lilies should not be planted near Asiatic lilies. Is this true?
Many lily enthusiasts don’t grow tiger lilies (Lilium tigrinum) because they are often infected with lily mosaic virus. Lily mosaic virus causes little harm to tiger lilies. Oftentimes, you can’t tell that they have the disease. However, aphids and other sap-feeding insects may carry the virus from the tiger lilies to other types. Many hybrid lilies infected with lily mosaic virus produce distorted foliage that is streaked or mottled. Also, infected plants produce fewer flowers and those flowers that do form are often deformed. Lilies exhibiting lily mosaic virus symptoms should be promptly dug up and discarded.
