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.
Farmers and gardeners have long known that marigolds make important companion plants all over the garden. Not only does the scent of the marigold (Tagetes spp.) repel animals and insects, but the underground workings of the marigold will repel nematodes (microscopic worms) and other pests for up to 3 years. They are especially helpful as deer-resistant plants.
