1 E. cuniculi are carried in the blood to other parts of the body, particularly neural tissue. 2  Spores from infected urine can remain in the environment for a month. 3  The parasites can infect and be shed by many other animals but seldom cause clinical disease in other animals.
Most annual flowers will die when fall brings frost. Marigolds, zinnias, petunias, delphinium and many other common flowering plants are examples of plants that frost will kill. In more northerly climate zones, it's difficult to get anything to bloom in the harsh winter months.
Marigolds will grow in nearly any warm to temperate climate. They do not survive well in colder climes. They prefer to be planted in full sun, approximately eight to 16 inches apart in moist, well-drained soil after the danger of frost has passed.
