I planted tansy to keep ants out of my garden. It did not work. Now it is a booger to get rid of. Invasive!

I do not grow this plant, information only.

Originally a European plant, it has escaped from gardens and in some parts of the country, as already noted, it can become quite invasive.

It made it into our alpine beds where it sent long tap roots down between the rocks, which made it impossible to pull out without taking out the small alpine plant growing in that space.
What a nightmare!

This is a beautiful, fast growing, hardy plant. The flowers are very attractive and it grows well here in West Texas. This plant shares m...Read Morey herb garden with yarrow, sage, germander, daisies and rosemary, (however it grows _away_ from the rosemary for some reason)

From my personal experience, please be aware that overdosing on this plant can be fatal, especially to dogs. Acording to Poison Control Center, there is no antidote known for Tansy poisoning, and we lost a 4 month old teething German Shepherd pup who decided to chew on the stem and root stalk. In small amounts, however, it is beneficial, as previously written, and I do use it sparingly, but since we lost the pup, it is now fenced well off from our other dogs.

Do not use Tansy when pregnant. Tansy is a herb to be used in moderation only as it can be toxic in large doses. It may also irritate sensetive skins.

The leaves were once used to preserve corpses from corruption. It was used as a strewing herb in public areas as a form of disinfectant and insect repellent. It deters flies and a bunch of flowers and leaves hung up in a room will keep them away (will keep most things away including any visitors with a sense of smell if too much is used). Fleas also dislike Tansy smell and can be rubbed on a dogs coat to repel them.

It has a culinary use, bearing in mind not to use much of it, in salads, eggs, some cakes and puddings. It was also used as a digestive aid in very low amounts.

Tansy's medicinal uses, in times past, was to rid stomach worms from children, treat jaundice, hysteria (it has stimulant properties), nervous conditions, as a rub on varicose veins, muscle sprains and rheumatic joints. It was also used to treat epilepsy but it can cause a fit as well as alleviate them.

The leaves are full of potassium and a valuable addition to the compost heap, this is good because if you grow Tansy you are going to have a lot of it.
