They named one of those plants after that property Heliotropium, meaning "sun turn".

Hopkins' bioclimatic law states that in North America east of the Rockies, a 130-m (400-foot) increase in elevation, a 4° change in latitude North (444.48 km), or a 10° change in longitude East (two-thirds of a time zone) will cause a biological event to occur four days later in the spring or four days earlier in the fall.

[3] The energy to facilitate this growth comes from reserves of carbohydrate stored in roots and wood of the vine from the last growth cycle.
