Yes, she is giving a wrong gardeners tip!
The article should say that the plants are tender perennials,
which are grown as annuals in northern climates.
This year I am over wintering coleus and pelargoniums.
One year I did over winter a basket of petunias.
I might try over wintering centradenia?
It is with the coleus which died off in the hail storm.
The centradenia never did flower outside.
The problem becomes room under the windows!
And sometimes some of the tender perennials can be encouraged to over winter where they are out in the garden if they are mulched. Snapdragons sometimes will, and this year there are Eklonis daisies which I might try mulching? They are more tender so?
