A medical sign is an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination or by a clinical scientist by means of an in vivo examination of a patient.

They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as Ipomoea muricata, are night-blooming flowers.
