Put the sunflower container in a nice sunny part of your house, garden or on the veranda (porch) if you prefer. A sunflower should be positioned so that it gets full sun all or most of the day; no sunflower can handle shade for most of the day. If you have the sunflower growing indoors, choose a sunny room but avoid placing it too close to a window because air near windows is often hotter or colder than the room temperature and this can be harmful to the plant.[4] Try to keep the container away from extreme rain.
